Do-it-yourself casing for an angle grinder for a vacuum cleaner

Any specialist who has worked with an angle grinder (“grinder”) for its intended purpose knows what kind of cloud of dust this tool creates during operation. Dust interferes with high-quality work, not only complicating visual inspection, but also severely contaminating the tool and nearby surfaces. Vacuum cleaners are used to remove dust from the work area. However, even the industrial version of the vacuum cleaner is a “point” device, and for it to work effectively, the suction tip must be brought exactly to the point of work. This task is accomplished by an attachment on a grinder for a vacuum cleaner, homemade or factory-made.

Purpose of the dust collector for angle grinders

Modern construction technologies provide for a large number of works that are performed with the help of an angle grinder.
Cutting metal parts does not present any particular difficulties, but there are other technological processes that produce a lot of fine dust. Special attachments for an angle grinder will be needed when carrying out the following types of work indoors :

Grilling floors or walls. In this case, a lot of dust is produced, regardless of the type of material. The greatest difficulty is that such work is mainly performed at high altitudes. In addition, debris falling from above settles evenly throughout the room. For these works, it is better to use a powerful bosch wall chaser.
Cutting tiles . This is the most common dust process. Dust from ceramic tiles is considered the finest and most harmful to human health.
Sanding wood floors. This is a very voluminous work that is performed over a huge area. That is why a lot of dust and small debris is released.

To successfully combat the formation of dust, manufacturers of angle grinders offer factory-made solutions to this problem. For example, it is recommended to install a protective cover for an angle grinder with a dust extraction under a Bosch construction vacuum cleaner. However, such a product is more suitable for large construction companies, since its cost is quite high. The home craftsman should make a homemade device that will be suitable for all types of work.

Causes of dust formation

The grinder is a universal tool. With its help, using various attachments, you can cut metal, stone, porcelain stoneware and tiles, process wood and other materials. But one of the disadvantages is the formation of a huge amount of dust.

Work that causes the formation of large amounts of small debris:

Grooving grooves on walls. The work is carried out using plaster, and cement and sand have a fine fraction. The height of the passage of the channels is at the level of one and a half or two meters. From such a height, dust settles evenly over the entire area of the room.
Sanding of wooden structures. Before painting or varnishing, wooden products must be removed from the cellulose fibers that form during the sawing process. Cellulose is thin, light and hangs in the air for a long time.
Removing old paintwork. Before applying fresh paint, the old paint must be removed. A flap sanding wheel is used. The paint it removes is fine.
Cutting floor and decorative ceramic tiles. Sintered ceramic has a fine grain structure and it penetrates everywhere.
Sanding parquet or wooden floors. Floor leveling occurs by removing the top layer. The irregularities have different heights and therefore, in addition to shavings, a lot of wood dust is formed.

Upon completion of the repair, dust must be removed from all possible cracks and cavities. To protect adjacent rooms from construction dust, protective screens made of polyethylene film or light fabric are installed in doorways. Special devices are also used that you can make yourself.

Homemade casing from a saucepan

In some cases, it is worth using a welding machine and making your own casing for an angle grinder for a vacuum cleaner from a thin metal sheet. This design will turn out beautiful and durable, but requires welding skills and expensive materials. If you have an old aluminum pan in your workshop, you can make a high-quality casing without using a welding machine.

For this work you will need the following materials and tools:

aluminum pan;
Bulgarian;
measuring instruments;
dye.

First, the main part of the dust collector is cut out.
It is necessary to carefully fit the casing to the electrical device. It is worth immediately accurately calculating the maximum penetration depth of the cutting disc, because the cutting height directly depends on this. mounting axis is cut out of the other part for mounting on an angle grinder. The diameter of the exhaust product is measured directly at the angle grinder. Its size must be as accurate as possible so that the homemade casing does not jump off due to high vibration during work. Experts advise using a strong tightening clamp when securing the device.

Using the same method, a universal pipe for the hose of a household vacuum cleaner is assembled. All edges of the product are very carefully curved inward along a single line to attach the side walls. Durable walls can be made from any type of material, for example, from a metal sheet. It is worth giving the device an aesthetic appearance, cleaning the joints and painting it with paint.

Complicated method

The second option will require an iron or aluminum pan. All actions take place in stages and do not require special skills in making additional equipment for the ushma. However, some tools are worth buying in order to do everything as accurately and efficiently as possible. And I wouldn’t want a hand-made protective element to cause injury.

Cutting out the shape for the angle grinder casing according to pre-measured dimensions

It is important to remember the saying: measure seven times and cut once. Why? It is unlikely that the spouse will be happy if, in order to save on equipment for ushma, she has to spend money and buy a lot of new dishes. From the remains of the pan, teeth are cut to the size of the grinder's torque sleeve

It is tightly secured to the grinder with a special clamp purchased in advance from the store. A cone is made from the same pan according to the size of the vacuum cleaner tube so that it can be tightly attached to the shape of the casing. It is worth recognizing that this may require considerable effort. It is necessary to cut a plate that exactly follows the shape of the future casing. And, accordingly, connect all the parts into one design.

The advantages of a casing made from a saucepan include the fact that there is no need to spend a lot, and you also do not need to have special welding skills. The negative aspects of this option include the scrupulousness of assembling the entire structure and, again, the inability to adjust the depth of the cutter.

Canister device

Home craftsmen have developed a more economical option for upgrading an angle grinder with a casing for a vacuum cleaner. In any workshop there will always be an unnecessary plastic canister for technical fluids. Such containers hold their shape perfectly, are quickly processed and have a factory outlet pipe of the required size.

To make such a product, you will need the following tools and materials:

plastic canister;
stationery knife;
fastening materials.

First, fitting is performed, the main criterion of which is to ensure the required immersion depth of the cutting blade.
Use a utility knife to cut out the required through holes. Their sizes are selected taking into account further preservation of the maximum rigidity of the product. Both mounting holes are cut out on both sides of the canister so that you can change the direction of rotation of the cutting disc. The hose of a household vacuum cleaner is attached to the neck of a plastic container and secured with a clamp. Next, you need to attach the casing to the angle grinder using a strong clamp and a special adapter ring. The assembly of this part must be treated with extreme care. The hole in the canister is closed with a lid, which can be moved to the opposite side when changing the direction of rotation of the cutting disc.

Such homemade dust collectors cost almost nothing, but are very useful. A construction angle grinder with dust protection allows you to perform any type of work in rooms with the least emission of fine dust. To sand floors, the shape of the nozzle should be slightly changed, but this will not require a lot of time and effort.

Cutting ceramic tiles without dust

It is very difficult to cut ceramic tiles using a factory dust extractor, because the cover covers the cutting area, and the builder needs absolute control over the work. For this purpose, it is worth making a homemade dust collector from transparent materials, for example, from a large plastic bottle.

This fixture is secured using the factory protective cover. The neck of the bottle fits very well under the socket of a household vacuum cleaner. This homemade transparent nozzle will help you complete the most difficult jobs. The master will also be able to control the insertion of the cutting disc into the ceramic tile. Upon completion of work, you just need to throw the garbage out of the bag.

Wet cutting technology for concrete

The use of water allows you to cut concrete with a grinder without dust and overheating of the tool. The technology allows us to solve several problems at once:

One way to ensure a continuous flow of water is to secure the hose so that the liquid flows onto the disc. If there is no running water in the work area, you can involve an assistant in the process. He will use a primitive device made from a plastic bottle to wet the circle. At the same time, the incision site is moistened with liquid.

This must be done carefully so that water does not pour into the instrument.

The method is not very applicable in multi-storey buildings, since there is a risk of flooding the neighbors from below.

Making a casing for an angle grinder to connect a vacuum cleaner

When cutting metal with an angle grinder, sparks occur, and when processing concrete, stone, granite and other similar materials, dust is generated. If you cut wood with a grinder, a large amount of shavings will appear during the work process. In order to process concrete and wood with an angle grinder with minimal clogging, you will need to make a casing for an angle grinder for a vacuum cleaner. You can buy such an attachment for cutting power tools, but making the device yourself will help you avoid costs.

Popular models

Protective covers for vacuum cleaners for angle grinders are available in a huge range.
Moreover, each type can differ not only in design, but also in functionality. Several models of attachments are extremely popular among craftsmen. Bosch 2605510224. This casing is suitable for angle grinders of various brands with 115 and 125 mm discs. It is equipped with a special ring brush, which allows you to perform work with a fiber attachment and a grinding wheel. The size of the nozzle is 200×190×80 mm, its weight is 0.3 kg. The cost is low.

STOMER 98299441. This device is made in the shape of a semicircle. It is installed on angle grinders with 230 mm discs. The main advantage of the nozzle is the presence of a guide, which is responsible for adjusting the depth of the storm. The casing size is 320x160x240 mm, weight is 2.71 kg. It can also be purchased at an affordable price.
Mechnik Air Duster. This option is suitable for tools with diamond blades with diameters of 125 and 230 mm. It is distinguished by its low price and the ability to connect to medium-power vacuum cleaners (up to 1.6 kW). The casing is lightweight and easy to install.

Blastrak. This is a professional protective cover for a vacuum cleaner that can be attached to sanding tools with 125 and 180 mm discs. The attachment has variable elasticity, is more rigid in the places where it is attached to an angle grinder and is soft at the edges in contact with the floor.
Metabo GED125. This casing deserves special attention. It is recommended to purchase it for processing concrete and stone. The nozzle is equipped with a special pipe that allows you to attach it to a vacuum cleaner.

Every craftsman, whether he is a professional or an amateur, cannot imagine his work life without an angle grinder, or popularly “grinder” or “ushma”. It is practically the main power tool in most jobs and many people try to buy it first. An angle grinder is not the safest type of tool, so its operation requires knowledge of safety regulations and special parts.

They are designed to ensure the personal safety of the worker himself and those around him, as well as to quickly and efficiently complete assigned tasks. What is meant by the phrase "special parts"? Various types of protective covers with dust extraction.

When purchasing an angle grinder, you can find a protective cover included, but this accessory, if you can call it that, will not be able to protect the room where the work is being done from dust. For this reason, many people buy or make a casing for an angle grinder under a vacuum cleaner.

When purchasing this attachment, you will need to familiarize yourself with information about what type of work it is intended for and what size disk the casing is made for. The advantages of such a purchase include adjustability of the depth of penetration of the disk, reliability and durability of the casing. The downside is that this accessory is by no means cheap.

What is the casing for?

Before you start working on concrete and wood, you will need to have a good idea of what the end result will be. When cutting with a grinder, dust is generated, which settles not only indoors, but also enters the human respiratory system. That is why work with the tool should be carried out exclusively in a respirator and safety glasses. To protect the room from excess dust, you will need to carry out work using a special attachment to which the hose from the vacuum cleaner is connected.

The attachment should be used on an angle grinder in the following cases:

When chipping concrete, brick, cinder block, slate and other similar materials. If gating is carried out during the construction stage, then the settling of dust in the room is not as dangerous as during repairs. When cutting durable materials, they are crushed, which causes the formation of dust that settles throughout the room
Cutting tiles and ceramic tiles - when processing these materials, dust is also formed, which is especially dangerous to human health. Tiles can be cut with special tile cutters, and no dust is generated, but if the work is done with an angle grinder, it is better to install a special attachment
Wood processing - when sawing wood, not only dust is formed, but also sawdust, which can be eliminated very easily and quickly using a casing mounted on the grinder

Manufacturers make special casings for angle grinders with disc diameters of 125, 150 and 230 mm. These are the most common types of cutting tools, which is why manufacturers produce special housings for dust removal specifically for them.

Craftsmen and specialists do not even doubt that a casing is needed on an angle grinder, since it is enough to try cutting concrete once to be convinced of the need to purchase or manufacture a dust collector. What is better, to buy or make a cover for collecting dust on an angle grinder with your own hands, everyone must decide for themselves. After all, the protective casing is relatively inexpensive, but in order to avoid costs altogether, you should make the nozzle yourself.

Purpose of the casing

As you know, any angle grinder has a standard protective cover. Its main task is to protect the operator from particles flying from under the tool and from flying debris in the event of a possible disk failure. If you make an angle grinder casing for connecting a vacuum cleaner with your own hands, then the standard casing is either used as a supporting base or removed from the machine.

The casing for connecting a vacuum cleaner to an angle grinder is used in many cases.

In construction:

“cutting” a groove in concrete;
sanding the rough coating of walls or floors for subsequent finishing;
cutting finishing tiles or building stones (brick, cinder block);
sawing wood or other non-sparking materials.

In metalworking:

When cleaning surfaces from rust;
Removal of old paint and varnish coatings;
Sanding the material before painting.

Both lists are incomplete, and the need to simultaneously use an angle grinder and a vacuum cleaner is determined when planning the work.

How to make a casing for an angle grinder for a vacuum cleaner - the best ways

The advantages of making your own nozzle are as follows:

There is no need to spend money on purchasing a device
Possibility to make a device according to your requirements
No need to travel around looking for the right device

There are many options for making a casing for an angle grinder for a vacuum cleaner, and when making it yourself, it is not at all necessary to make the kind of equipment that has already been invented. It all depends on personal abilities, capabilities, as well as the available material from which the nozzle is planned to be made. To make the work of making casings easier, let’s consider several options for converting an angle grinder into a vacuum cleaner.

About the Sander Guard

So, a casing for a grinding machine is a kind of equipment that allows you to ensure safety when working on such angle equipment. The operator is freed from constantly monitoring the work process and this makes his work much more efficient. To install such a casing on a grinding machine for protection, you need very reliable and, accordingly, special fastenings.

Such equipment has several functions: protective, and it is this kind of protection that helps to avoid not only human injuries, but also damage to the material itself, for example, any cracks or chips.

Functions of the grinder attachment:

Usually, when sold, such protective equipment comes complete with an angle grinder. Why can working with a grinding machine be dangerous without life-saving equipment? The thing is that when the work process is underway, all the cutting and grinding discs begin to collapse, turning into small residues.

We make a dust extractor from a plastic canister ourselves

The easiest and most economical option to make a casing for an angle grinder under a vacuum cleaner is to use a plastic canister as a base. To implement this version of the casing, you will need to take a canister of the appropriate volume. Usually a one- or five-liter canister is enough, but it all depends on the size of the tool itself.

The principle of manufacturing the casing is quite simple, and to implement it you first need to prepare a drawing according to which the dust removal nozzle is made. When manufacturing, the following factors must be taken into account:

The size of the nozzle is taken into account, which depends on the depth of immersion of the cutting disc. The larger the size of the nozzle, the shallower the depth of the resulting cut.
Holes of the required diameter are cut depending on the size of the bushing to install the device on the shaft of the power tool and secure it
A hole is made on one side to secure the device to the shaft of the power tool. On the other hand, it is not at all necessary to make a hole, since dust can leak through it, which will reduce the effectiveness of the nozzle
The neck of the canister is used as a bracket for connecting the hose from the vacuum cleaner. To connect the neck of the canister with the hose from an industrial vacuum cleaner, use a tie or clamp

To make such a device, you will need a minimum of time, effort and money. The result should be a device for removing dust when cutting concrete, tiles and wood.

Nozzles for grinders for grooves

The wall-cutting attachment for the grinder should include:

The basic conditions for the functionality of such an attachment are as follows. The grinder must have a sufficiently powerful drive (at least 1500 W), and the length of the shaft on which the main saw blade is installed must be sufficient for mounting an additional disk, with the help of which the second wall of the groove will be formed.

The diameter of the saw blade itself is also important, on which the safety of work and the depth of the cut groove depend.

The type of bearings on which the shaft rotates is also important: the presence of a second disk increases the unevenness of the load, so conventional ball bearings, the permissible axial force on which is small, will fail very quickly, with a corresponding jamming of the shaft and failure of the equipment. A tool with needle or roller bearings is required.

Finally, when the shaft rotates, the movement of the saw blade should be towards the worker, and not away from him (in the latter case, the total torque will push the grinder away from the groove obtained with its help).

A purchased wall chaser attachment for an angle grinder is prepared for work like this. The protective casing is removed from the gearbox. An additional bushing is mounted on the main shaft, which securely compresses the shaft using a clamp fastening.

The first diamond disk of the required diameter is installed on the shaft - from 150 to 230 mm; larger sizes will lead to an increase in the cantilever load on the bushing. It is not recommended to replace the diamond disc with another one, especially if grooves need to be made in concrete. A support washer is placed on the sleeve (usually, professional nozzles come with several such parts of different thicknesses, which determine the width of the groove).

The vacuum cleaner attachment is secured to the dust extraction cone using regular tape. The grinder gearbox is attached to an extended control handle. It should be noted that any wall chaser attachment for an industrial grinder has a seat for a removable handle, which is unified with a standard handle from the same manufacturer of the main tool. This is a limitation of the design under consideration.

After this, check the alignment of both disks, attach the housing to the lever support, set its stroke, and check the reliability of fixation of all elements of the nozzle at idle, and then during the working stroke.

Dust extraction from an old saucepan

If sheet steel is available, then it can be used as a basis in the manufacture of a dust extractor for an angle grinder. When carrying out such work, you will need a welding machine. If you don’t have a machine, you can make a nozzle from an old aluminum pan. The principle of making a device from an aluminum pan is as follows:

The basis is taken from a part of the pan with the bottom. The bottom acts as one side of the nozzle, and the other side is made by bending the sides of the pan
It is recommended to use rivets to connect sheet aluminum
A hole of the appropriate diameter is drilled in the wall of the dust collector for fastening to the shaft of the power tool
To secure the hose from an industrial vacuum cleaner, you will need to make a hole on the outside of the side wall to which to attach the neck of a plastic canister, bottle or plastic tube. It can be secured to the aluminum base using threaded connectors with washers
The reliability of the connection between the hose and the nozzle is ensured by a metal clamp

How to make a casing for a vacuum cleaner for grinding with an angle grinder

If a grinder is used not only for cutting, but also for grinding, then to prevent the formation of dust in the room it is necessary to make a protective casing that will have a special design. Such a casing is somewhat more difficult to produce, but it is quite possible. As a base, you can use a five-liter plastic bottle, a CD container or a plastic bowl of a suitable size.

When making a casing for an angle grinder for a vacuum cleaner for grinding, the following factors must be taken into account:

The working area will not be at the bottom of the tool, but at the side. To do this you will need to make a device with an open side part
Make a reliable bracket for connecting the device to a power tool
Connect the hose from the vacuum cleaner to the homemade workpiece
To ensure contact of the sandpaper with the surface being treated, the walls of the device must be shorter than the protrusion of the abrasive nozzle

When performing work, you will need to use a hot glue gun. With its help, the production of ideas is not only simplified, but also accelerated several times. The result is an attachment for a grinder for grinding wood, metal and other similar materials. The entire process from A to Z for making a cover for grinding is described in the video material.

Canister

If you don’t have welding skills or your wife flatly refuses to give permission to damage the pan, then there is a third option, how to make a protective casing with a dust extractor, which also miraculously connects to the vacuum cleaner tube. What will you need for this?

Find a canister in your garage, closet, or at your neighbor's. Using a construction knife or an ordinary knife, you will need to cut out constructive holes from it, in accordance with the shaft of the grinder and the location of the disk on it. It would be good to remember about safety precautions. Why? Trivial - to preserve the integrity of the hands

Moreover, it is important to choose the right knife. It should have a high-quality handle and fit well in your hand without slipping out

Afterwards, you need to attach the vacuum cleaner tube to the neck of the canister so that it becomes like a nozzle. How? Cut the neck lengthwise and put on a clamp so that you can then tighten the vacuum cleaner tube with it.

It is important to remember that in order to achieve good suction of the vacuum cleaner, it is necessary to ensure that all parts of the casing fit snugly against each other

Application of cover for cutting tiles

The manufacturing options for the casings under consideration are suitable for removing dust when processing concrete, brick, cinder block and wood. When cutting tiles, one important condition must be taken into account - the accuracy of the cut. When working, you need to see the mark along which the power tool is guided, thereby making the cut. It is impossible to see the disk through steel or plastic casings, so when using a device for tiles or ceramics, it is important to make it from transparent materials. The easiest option for this is a plastic bottle.

It is not difficult to make a casing from a plastic bottle, and to do this you will need to make one hole in the wall for installation on the shaft, and connect a hose from a vacuum cleaner to the neck. It does not matter for which brand of angle grinder the device is made - Bosch, Interskol, Makita, Diold and others. All tools from different manufacturers have a similar design, so the manufacturing principle is the same for all.

Through the transparent cover you can control the movement of the rotating diamond disk. Moreover, it is recommended to use solid discs for ceramics, since segmented ones contribute to the formation of chips, and as a result the material may be damaged. Moreover, cutting must be done in one pass, otherwise the cut of the tile will turn out uneven. Having made a homemade casing for an angle grinder under a vacuum cleaner, you can test it in action, making sure of the usefulness of such a device.

Grilling walls with a grinder or the effectiveness of this tool

You can make a channel with a grinder in walls made of materials such as brick, concrete, cinder block, tiles, tiles, and other types of materials. To crush these materials, specialized attachments are used—diamond-coated disks. The process of how to make a groove with a grinder consists of the following steps:

Marking is the most important part of the work, which consists of drawing lines with a marker or pencil on the surface of the wall. To apply markings you will need a pencil, a tape measure, and a rule or water level. When applying markings, you need to make the lines bolder so that when you move the cutting tool, they can be seen. Cutting a groove involves “passing” the tool along the drawn lines. The tool must be held firmly and moved slowly

In this case, it is important to wear special protective equipment, such as goggles, a respirator and gloves. Making a channel - after cutting the lines with a cutting disc, you will need to cut out the remaining concrete. These residues should be removed using a hammer and chisel or a hammer drill.

You can attach two discs to a grinder, just like on a wall chaser. This will allow you to do double the work at once. In one “pass” the tool produces a finished channel. When working to make a neat channel, a large amount of dust is released. To prevent dust from settling in the room where repairs have already been completed, a special attachment is used to which the vacuum cleaner is connected. The vacuum cleaner sucks up all the released dust that occurs during the concrete crushing process.

This is interesting!
In the design of angle grinders, you should use exclusively diamond wheels that are designed for cutting concrete. The use of abrasive and other types of discs is unacceptable. An exception is the use of saw blades with teeth, which can be installed in the spindle of an angle grinder to cut a channel in a wooden wall.

How to use an angle grinder: tips and tricks from experts

The manufactured attachment on the grinder not only eliminates the formation of dust, but also acts as an additional protection for humans from the negative effects of power tools. An angle grinder is a life-threatening tool that is used for a variety of tasks. It is important to follow safety precautions when performing these tasks to prevent injury or injury.

Experts recommend following a number of the following recommendations when working with power tools:

Hold the instrument with two hands only
Use only suitable cutting discs and wheels depending on the materials being processed
Do not get carried away with wood processing using an angle grinder. An angle grinder for working with wood is not the best option
Carry out work in protective clothing - goggles, respirator, gloves, etc.
Pause periodically to allow the instrument to cool down.
When using a casing, it is necessary to ensure that it is tightly fixed to the power tool. If it vibrates, it may fall under the rotating disk and be damaged.

To make a homemade casing for an angle grinder to connect a vacuum cleaner, you will need to show a little ingenuity and imagination. Making a device is not at all difficult, and you just need to choose the right material to use as a basis. It can be not only plastic or metal, but also wood, for example, chipboard or fiberboard. And at the same time, you don’t need to buy a homemade device in order to ultimately carry out one-time work on processing concrete, wood or tiles with an angle grinder.

Features of cutting with a grinder

After choosing the equipment and the circle for it, before cutting concrete with a grinder, you need to familiarize yourself with the recommendations for carrying out the work:

The tool must be held with both hands

In this case, if a reverse strike occurs, it can be held, which will minimize the displacement of the cutting line; Work should be carried out only on a flat surface so that the person’s balance is maintained; The power cord should be located on the opposite side of the drive to prevent accidental damage to it. A cut cord can cause a shock wave from the unit and a short circuit in the electrical network; The tool must be held firmly in your hands until it stops completely; When changing the place of sawing, the grinder must be turned off so as not to accidentally touch surrounding objects; In the event of a power outage, be sure to disconnect the equipment from the network

This will prevent it from turning on when electricity is supplied without operator control.

Cutting concrete along a line

After the grinder for concrete has been prepared, work can begin.

The cutting line is outlined. At the same time, it is advisable to fasten wooden blocks along the line, which will make the cut line more even;
The grinder is turned on and a cut is made with a depth of approximately 5 - 10 mm;
The bars are removed;
A cut is made to the required depth. If the cut is made dry, the procedure should be stopped periodically to allow the instrument to cool.

The video shows in detail how to cut concrete with a grinder correctly. The process is best performed with the tool cooled.

An ordinary spray bottle sprays water directly onto the furrow to reduce the amount of dust;
Water is sprayed directly onto the disk, in the absence of a nearby power source. This will reduce the heating of diamond blades and extend their service life;
If it is not possible to spray liquid onto the disc, cooling can be done with air. Periodically, the circle should be removed from the cut and given the opportunity to work in the air.

The casing (case, attachment) for an angle grinder performs several functions : it serves as protection for the performer, and acts as an element for collecting dust and other debris. Thus, the cover is an essential part of the grinder when carrying out various types of work. This article is devoted to the independent production of casings. In addition, site visitors may be interested in articles about housings for vacuum cleaners and detailed material about all their types.

Types of casings

Sanding attachment housing

The types of equipment for grinders that perform dust collection and removal tasks are quite numerous.

Manufacturers are aware of the problem and solve it by producing special devices for their equipment.

Based on the type of functionality, two options are available:

for cutting discs;
for grinding discs.

The first ones outwardly resemble conventional protection with a closed housing and a pipe for a vacuum cleaner. The second option is a closed lid with an outlet for connecting a vacuum cleaner hose. Both types are installed in the usual way on an angle grinder and do not require special tools for installation. Most users are familiar with the common models:

Stomper SG-230;
Stomper SG-230 R;
BOSCH 1605510180;
BOSCH 2605510107;
BOSCH 2605510224;
BOSCH 2602025285;
Metabo GED125;
Metabo GED125 Plus.

Types of covers for grinders

There are several types of covers for angle grinders:

attachments for vacuum cleaners are used when chipping walls, sanding surfaces and performing other work during which a large amount of dust, particles and other debris is formed;
covers designed for grinders with different disc diameters;
nozzles made of metal and plastic;
with and without fastening;
with slides - special guides;
various brands: Russian and foreign.

How to make a nozzle with your own hands

The following are videos demonstrating the process of making a casing for an angle grinder with your own hands. Craftsmen use various materials and technologies for production.

Homemade for gating, for a vacuum cleaner

Dust extraction covers are the most popular type.

Homemade protective casing for a diamond bowl from a plastic stand, corner and clamp

The base for the cover is a plastic stand for a flower pot.

A hole is made in the center: several cuts are made, the workpiece is heated and the edges are moved back.

A hole is formed at the edge for the PVC corner, which is then attached by soldering to the stand.

It is recommended to cover the rim with thick fabric or foam rubber to trap debris.

Casing made of a plastic bowl, pipes with a diameter of 40 mm. and clamp

To make it you will need a plastic cup and a pipe with a diameter of 40 mm. and a clamp.

A hole is drilled in the center of the bowl using a drill, “petals” are cut, and the edges are moved back by placing a pipe in the hole.

The workpiece is tried on a drill, the “petals” are cut off a little.

Using a clamp, the workpiece is attached to the angle grinder and made smaller in height; unnecessary parts are removed with scissors.

To make a dust extractor, another hole is made. The pipe is attached to the workpiece using wire stitching, and the joint is coated with silicone.

On the inside, the edges of the cover are covered with double-sided tape and door tape, which will keep dust out.

Upgrading the metal casing with a dust extractor and a curtain to adjust the cutting depth

Two plates of a similar shape are welded to the metal casing, thereby providing greater protection to the nozzle.

A hole is formed on the cover, a tube with a diameter of 25 mm is welded, i.e. dust removal is done.

There will also be a movable plate on the bottom side of the nozzle, which is secured using a curtain welded to one of the sides.

On the other side, a plate with holes for a bolt is attached. It is used to adjust the cutting depth.

Peculiarities

A housing for an angle grinder for a vacuum cleaner is a special attachment that allows you to protect the technician from exposure to dust, which flies out from under the disc when working with a grinding tool. Many hardware stores offer respirators for protective purposes, but these devices are ineffective. After a few hours of operation, they begin to clog, which means they cannot cope with their functions. Additionally, respirators are not designed to remove dust from a work area. Therefore, if renovations are being carried out in a residential area that has decorative finishes and furniture, it is necessary to use an angle grinder with a dust extraction.

Most designs of grinders include a dust collector. Thanks to it, dust is immediately collected from under the working surface of the device, without polluting the room. Such models are characterized by high suction power. They protect not only from dust, but also from debris. Additionally, a protective casing made of durable material is installed on the dust removal mechanism. It is able to withstand intense mechanical loads and, during surface treatment, collect different fractions, including small dust particles and pieces of metal or concrete.

The protective casing for a vacuum cleaner performs two main functions.

Since cleaning is performed with a vacuum cleaner connected to the nozzle, when installing the casing, it is necessary to ensure that the diameter of the dust extraction tube and the opening of the nozzle correspond to each other. The nozzle in the form of a flexible hose must fit exactly into the hole and fit onto the casing without any play.

It is recommended to use a housing for a vacuum cleaner in the following cases:

The housing for the vacuum cleaner can be sold either complete with the tool or separately. At the same time, many craftsmen make protective devices with their own hands to protect the work process. A homemade casing is no different in functionality from a factory one, but may be slightly inferior in performance. Self-made casings can protect the craftsman from injury by preventing particles of the processed material from flying away. But if financial capabilities allow, then it is better to purchase finished products, as they are of high quality and allow you to expand the capabilities of the device.

Housing for an angle grinder for a vacuum cleaner

The grinder is not only a popular type of tool, but also easy to use. To use the tool, you do not need to have any special skills, but it is important to follow safety precautions. When working with an angle grinder, dust actively appears indoors when concrete, wood, and ceramics are being processed. Especially in order to avoid the occurrence of dust, casings for the grinder under the vacuum cleaner were invented and manufactured. With this device, working with an angle grinder has become even easier and more enjoyable.

Housing options for angle grinders

You can make housings for an angle grinder for a vacuum cleaner yourself, so there is no need to spend money on a factory attachment. In addition, there are more than enough options for making a homemade casing. Let’s look at a couple of options for making attachments for an angle grinder that will help you carry out work indoors “without noise and dust.” As for noise, the use of such attachments also reduces the noise level, although only slightly.

The first version of the casing involves the use of a pan. You can make a casing from a pan without much difficulty and even without the use of a welding machine. The only condition is the presence of an old aluminum pan. To make such a nozzle, you will need to cut out the casing from the pan, adjusting it to the size of the power tool.

It is important to know! The use of a material such as steel will not be relevant, since welding will be required to make the casing.

Having decided on the depth of penetration of the circle, you should remove the excess part of the pan, which can also be done using a grinder. In the resulting part of the pan, you need to cut a hole for the landing axis. The axle diameter can be measured directly using the grinder itself. The diameter must be as accurate as possible, otherwise the nozzle will slip off during operation.

In the back of the resulting nozzle, make a hole for the vacuum cleaner hose. This hole, called the dust chute, is where the vacuum cleaner pipe should fit into to suck out the dust. The presence of a dust collector or dust extractor allows you to perform the main task, to prevent the occurrence of dust in the room when working with a tool. At the final stage, the edges of the casing should be bent inward, with their help the side wall will be fixed.

The side wall for the protective casing of the angle grinder can be made of any material. It is best to use a thin sheet of galvanized steel or straighten the rest of the pan. A suitable piece of metal should be cut out and screwed to the main product with self-tapping screws. The photo below shows a view of the resulting casing for an angle grinder with your own hands.

You can also make a casing from a plastic canister. This option is also economical and even easier to implement. First you need to find an empty plastic canister, which is sure to be in the garage. We begin to take measurements, since an important condition is to ensure the required immersion depth of the circle.

It is important to know! The size of the required canister depends on the angle grinder. For grinders, a liter can of oil or brake fluid is suitable for a 115 mm disc.

The work of cutting out the casing is carried out with a construction knife. The neck of the canister should be left, as it will play the role of a dust outlet or for attaching a hose from a vacuum cleaner to it. We recommend cutting a hole at the level of the angle grinder axis, the size of the nut securing the working disk. This will make it easier to replace an erased disk.

After the product is ready, you can put it on the instrument and try it in action. It should look something like the photos above and below. Such a casing is not only easy to manufacture, but also does not require any additional costs.

Depending on the material and manufacturer, factory attachments will cost from 600 rubles, but is it even worth buying such a device when you can make it yourself without much difficulty. The above options are especially relevant in cases where you need to perform one-time work indoors, but at the same time you want to reduce the occurrence of dust.

Only a construction vacuum cleaner must be connected to a homemade or purchased casing for an angle grinder; it is designed to operate in this mode. We strongly do not recommend using a home version of a vacuum cleaner, as it will not be able to cope with large volumes of dust. It will very quickly fill (clog) with dust, which can lead to breakdown.

General recommendations for using an angle grinder

When working with a tool such as an angle grinder, safety precautions must be observed. A vacuum cleaner cover for an angle grinder is not only an option to avoid littering the house when doing work. The advantage of such a cover is that it protects the person doing the work from various factors. Working without a casing is like playing Russian roulette: you will be lucky or unlucky.

During operation of an angle grinder, negative consequences such as breaking the wheel are possible, which often happens with abrasive discs, as well as the occurrence of small fragments and stones that can get into the eyes. The danger of dust generated during the processing of concrete and ceramic products is that it can reach the lower parts of the respiratory system. It is strictly prohibited to carry out work cutting concrete or ceramics without a protective casing and a respirator. It is especially important to use a respirator and safety glasses if work is performed without the use of a protective cover.

An angle grinder is an indispensable assistant when performing various jobs. With the advent of such a tool, human manual labor has become much easier, but at the same time the likelihood of injury has increased. To ensure that the tool continues to be the best assistant in the household, design a homemade case for it, protecting yourself from possible serious injuries.

Self-production

Making a casing for an angle grinder for a vacuum cleaner with your own hands requires a clear idea of what needs to be done and why.

An angle grinder is a potentially dangerous tool and can cause serious injury if handled incorrectly.

Standard casing

A version of a homemade device made on the basis of a standard casing, shown in the photo below, was created as follows: two semicircles were cut out of plywood 0.5 cm thick. The dimensions of these parts are selected so that when connecting them into one, a third element can be inserted between them - a strip of plywood, thick paper or plastic. The result is a semicircular box, in the lower part of which a round hole is cut for connecting a vacuum cleaner hose.

The device is mounted on an angle grinder, like a regular standard protection, and the working disk is located inside it. It should be noted that the device can only be used for cutting or sawing materials; it is not suitable for flat grinding.

The idea of making a protective cover for an angle grinder for use in conjunction with a vacuum cleaner, using standard protection, is not new. At the same time, masters use any things at their disposal.

Plastic canister model

The device is created from an old plastic canister of a suitable size. For manufacturing, select a canister of such a size that its width is 1-1.5 cm wider than the working body of the angle grinder. To connect a vacuum cleaner to an angle grinder using such a device, you need to prepare tools and materials.

Plastic canister.
A piece of plastic equal to the size of the side wall of the canister.
1 large clamp for securing the casing to the body of the angle grinder.
1 medium size clamp for fixing to the hose housing of a vacuum cleaner.
4 self-tapping screws of the shortest length, for example, 3x10 mm.
Shoe or segment knife.
Marker.
Ruler.
Screwdriver.

Manufacturing begins with cleaning the container from the remnants of the liquid stored in it. With a marker and a ruler, mark a hole in the center of one of the side walls of the canister with a diameter equal to the diameter of the standard clamping nut of the angle grinder. Cut a hole and transfer its center to the other sidewall. A hole is marked on it, the diameter of which is equal to the outer diameter of the seat of the support bearing of the angle grinder. The end wall of the canister is cut off opposite to the wall on which the neck of the canister is located. For greater strength, you don’t have to cut off the end wall completely, but cut out a “window” in it, stepping back 1-1.5 cm inward from each edge of the end wall.

Attaching a dust collector from a canister to an angle grinder is done like this: after removing the disk and support washer, put the casing on the angle grinder with the side on which the hole for the support bearing is cut. Next, if the height of the support bearing seat allows, a clamp is put on this seat and tightened. The wall of the device is sandwiched between the front plate of the angle grinder gearbox housing and the clamp. If the height of the bearing seat does not allow the “device” to be secured with a clamp, the wall of the former canister is pressed against the gearbox housing and the points of contact with the coupling bolts are marked on it. Having removed the casing from the machine, holes are made in the marked places with a diameter equal to the diameter of the bolts. They unscrew the gearbox bolts, and without disassembling it, put on a new device and, together with it, screw the bolts into place. After securing the device to the body of the angle grinder, put the support washer and working disk in place and secure it with a nut. The hole remaining on the front side is closed with a shield cut from existing plastic, securing it to the dust collector body with self-tapping screws.

A hose from a vacuum cleaner is attached to the neck of the former canister, securing it with a clamp - the tool is ready for work.

Before starting work, you can draw a line on the outside of the device body with a bright marker that corresponds to the line of travel of the working disk - it will be easier to control the evenness of the cut.

Tile cutter attachment

Among homemade devices, special mention should be made of devices for collecting dust when working with finishing tiles. When grinding or cutting a groove, there is no particular need for strict control of the stroke of the working body. Working with a tile cutter requires constant visual monitoring of the evenness of the cut. Dense metal or other opaque casings do not allow this to be done.

The best way out of this situation is to use a regular transparent plastic bottle with a capacity of 5 liters. The neck of the bottle will act as an outlet pipe. Remove the working disk, support washer and protective casing from the grinder. Having attached the bottle with its side wall to the machine shaft, mark on it the location of the cut-out hole for fastening. Then, putting the working disk on the shaft without securing it, mark the height of the future dust collector. It has been experimentally established that it should be such that the working disk protrudes from the body of the bottle to the thickness of the tile being cut plus 1.5-2.0 cm.

Having received the required dimensions, the future device is removed, the excess height is cut off and a hole is cut. The resulting dust collector is installed on the machine in the following order:

put the device on the front side of the angle grinder gearbox;
put on the standard protective casing so that it tightly presses the new structure;
install the support washer, working disk and secure it.

After attaching the vacuum cleaner hose to the neck of the former bottle, the tool is ready for use.

In conclusion, it is necessary to once again recall safety precautions: when working with angle grinders, the use of personal protective equipment is a prerequisite.
