Choosing attachments for an angle grinder for wood processing - types and characteristics

The most popular tool for sanding wood is the grinder. This device has many advantages compared to other equipment designed for wood processing. The grinder is characterized by high productivity, provides high speed and excellent grinding quality. Using an angle grinder, you can perform the entire range of wood sanding operations: from roughing to surface polishing. The required effect can be achieved by attaching an attachment to a grinder for sanding wood. There are a lot of attachments, and those uninitiated in the intricacies of the work can make a mistake in their choice, which will inevitably affect the quality of grinding. What attachments exist for wood processing, how to choose them and use them correctly, we’ll talk about this.

Wood sanding attachments

Special attachments have been developed for the grinder, which allow for brushing, peeling, milling, and other work. It is necessary to select the right tool in accordance with the material and type of work. The grinding attachment on the grinder is used depending on the degree of processing of the material; they differ in shape and size.

Peeling attachments

Peeling type attachments are used in most cases to remove the top layer from a surface or paint coating. Various types help to carry out work in accordance with the required technical parameters.

1. The end of the product is ground down using an attachment with crumbs and spikes, and an abrasive grinding emery wheel.
2. Thanks to a variety of spiked attachments, it is possible to process surfaces of different heights and grind off the required layer.
3. Their twisted wire attachments are used for rough cleaning of wooden products and have various modifications.

It is important to understand that using coarse wire or peeling attachments for an angle grinder can be unsafe; during operation, it is possible to catch a nail or a thick rod, which will lead to the tool flying out of your hands

Grinding and polishing attachments

Various surfaces, including wood, are sanded using a special type of attachment. The kit is secured by using a bolt, which is screwed onto the shaft and tightened with the bolt. It is often equipped with a special device that secures it to the drill.

Felt discs are used instead of a wheel for sanding wood; the structure is attached with Velcro, which allows you to replace the used tool without removing the grinder from the shaft. The petal disc has become widespread in wood processing. The name is taken from the shape and location of the processing surfaces.

The use of a grinder or grinder depends on the specific situation. For applying regular paint, a wood sanding attachment for an angle grinder is suitable; deeper processing with an angle grinder is not allowed, because After painting you may notice scratches. A longitudinal belt sander moves in one direction and uses different grits of sandpaper.

What you need to pay attention to when choosing an attachment for an angle grinder

Some grinders come with a small diameter of the installed nozzle; as a result, craftsmen remove the protective casing, which is very dangerous when working with wood. It is necessary to take a break when working with the tool, because... Wood chips can clog the cooling holes in the case. The grinder is used only for processing wood; a special machine is used for cutting.

Other grinding accessories

Another tool used for sanding wood is a Dremel. This is a mini universal device. With its help, you can perform a wide variety of woodworking tasks with high precision: grinding, polishing, engraving, milling, drilling. It is used extremely rarely for grinding large parts, but if you need to apply a drawing or engraving on a wooden surface, then it has no equal in this work.

When sanding wood with a grinder or drill, marks from the sanding discs often remain on the surface in the form of lines, grooves, and depressions. Very often this happens due to inept handling of the tool and when working at high speeds. It is quite difficult to get rid of these marks; you have to sand the surface again by hand.

For manual grinding, you can use a simple device that our ancestors used to grind - a sanding block. It can be made from a rectangular wooden plank. The board must be wrapped in sandpaper and secured with nails or screws.

During grinding, a lot of dust is generated, which settles not only on the surface, but also enters the respiratory system. A log sanding mask, which is made from a special fabric that does not allow dust particles to pass through, will help protect your nose and mouth from dust.

Milling

Milling attachments are produced in various designs; a distinctive feature is the size of the abrasive grains. According to their intended purpose during work, such attachments are similar to rasps; the use of an angle grinder allows you to increase the speed of processing the material. Craftsmen use these devices for final processing of wood.

Special cutters are produced, there is an abundance of assortment on the market, each tool differs in purpose and features. Main areas of application:

• preliminary alignment of edges;
• sawing or cutting out a bowl from small-section blanks;
• groove sampling.

When working with milling and grinding attachments with a grinder, it is prohibited to remove the protective device - the tool casing. Each tool has a technical purpose and instructions, which clearly describe the materials suitable for use and the operating modes of the tool.

Let's look at attachments for various types of sanding wood products

Cord brushes

Designed for rough sanding and leveling the surface of wood. With the help of such a tool, the workpiece is given its final shape.

End discs

Designed for leveling the end of the workpiece. Most often, this need arises when making bevel cuts. The operation of this disk resembles a file, only the performance is an order of magnitude higher.

Flap sanding attachments

The most common segment of accessories for grinders. Can be used to process any materials, including wood.

Depending on the size of the abrasive, either the uneven layer is quickly removed, leaving the surface rough, or all unevenness is smoothed out without removing a large thickness. Correct use is a consistent transition from coarse-grained fraction to finer processing. Thanks to the rigid base, they allow great pressure to be applied to the workpiece to increase efficiency.

Structurally, they consist of trapezoidal petals of sandpaper, overlapped with a three-quarter overlap. Due to this, when erasing the edges, the next layer works. The wear of the nozzle is quite slow. For cleaning wooden products with complex relief shapes, a petal nozzle with a radial arrangement of sandpaper strips is designed.

The tool requires certain skills

If handled carelessly, protruding parts of the workpiece can easily be “chipped off.” Before use, it is recommended to practice on unnecessary pieces of wood.

Grinding wheel with Velcro

Most angle grinder owners associate this particular attachment with the concept of a grinding disc for wood. It is difficult to imagine a more universal device for sanding wood. Round sandpaper with a special coating is attached to the work surface, and you can begin sanding surfaces of any area. It is enough to purchase such an attachment once, and all that remains is to change the sanding wheels with any grit.

The work efficiency is many times higher compared to a conventional manual grater. With the proper skill, such a disc can process edges no worse than with a molding cutter. And for updating furniture with cracked varnish or paint, you won’t find a better tool. Surfaces can be cleaned with virtually no reduction in thickness. After painting, the product will look like new.

Without a special polishing machine, you can use this attachment to scrape parquet. True, it will be necessary to take care of removing dust and sawdust. And after varnishing, the floors can be polished using the same angle grinder and special polishing attachments.

Attachment for grinder for sanding wood - types and application

The most popular tool for sanding wood is the grinder.

This device has many advantages compared to other equipment designed for wood processing.

The grinder is characterized by high productivity, provides high speed and excellent grinding quality.

Using an angle grinder, you can perform the entire range of wood sanding operations: from roughing to surface polishing.

The required effect can be achieved by attaching an attachment to a grinder for sanding wood. There are a lot of attachments, and those uninitiated in the intricacies of the work can make a mistake in their choice, which will inevitably affect the quality of grinding. What attachments exist for wood processing, how to choose them and use them correctly, we’ll talk about this.

What you need to pay attention to when choosing an attachment for an angle grinder

When choosing a grinding disc, you need to take into account the power and size of the grinder.

For devices of different sizes, circles are selected that are designed for a certain rotation speed.

The main rule when choosing attachments for an angle grinder is that the wheel for sanding wood must have a certain thickness; the use of wheels of small thickness is not allowed.

What parameters are decisive when choosing a disk:

1. External diameter. The larger the size, the higher the processing speed and the longer the service life.
2. Landing diameter. To attach a larger circle, use a special adapter for an angle grinder, which has a mounting hole of the required size.
3. Disc thickness. The larger it is, the longer the nozzle will last.
4. Grain. The size of the fractions is selected in accordance with the type of processing.

When working with an angle grinder, you must take precautions; inept and improper handling of the tool can lead to injury.

High rotation speed and heavy load on the device can cause the disc to break into pieces, which can injure a person. Before work, you need to check the correct position of the circle and the strength of its fastening.

All movements of the grinder should be made smoothly and softly without vibration.

The processing of a wooden house takes place in stages: first, rough surface treatment is carried out, then finishing, and at the final stage, finishing sanding is performed. Accordingly, the nozzles presented on the market today are divided into varieties that differ in purpose, shape and material of manufacture.

Coarse attachments

There are several types of attachments used for roughing wood. Their main purpose is to remove large inclusions, bark and knots from the wood surface.

1. Grinding wheels structurally consist of a disk with soldered metal wires. The steel bristles can be positioned parallel or perpendicular to the tool. The wheels do an excellent job not only with rough processing, but also with peeling off old paint or varnish.
2. Cord brushes are a disk with metal fibers, horizontal. An abrasive brush is suitable for rough sanding and surface leveling.
3. End discs are used for processing bevel cuts and leveling the ends of logs.
4. Metal brushes consist of bristles made of stiff wire, which are positioned perpendicular to the tool. Used for initial treatment and removal of old paintwork.

Attachments for gentle grinding and polishing

1. Flap attachments for angle grinders are the most common. They consist of many trapezoidal petals made of abrasive material, which overlap each other. Thanks to this design, the nozzle wears out slowly. Depending on the degree of processing, you can choose discs with different grain sizes.
2. Grinding wheels are made from sandpaper, felt, sponge, thick fabric and are usually sold in a set.
   The discs are equipped with Velcro, with which they are secured to the plate attachment. The set for sanding wood consists of five circles made of the same material. They are very convenient to use; the worn disk is easily removed from the main nozzle, and another abrasive is placed in its place. Velcro wheels are used for fine and finishing sanding. You can polish wood with soft fabric and felt discs by applying a special wax-based polishing paste to the surface.
3. The cup attachments are a nylon brush consisting of many bristles of abrasive nylon. Used for fine sanding of wood.

Grinding machines

In addition to the grinder, other equipment is used for abrasive grinding. Today there is a wide range of different grinding machines:

1. Belt machine for sanding timber. The machine performs grinding using an abrasive belt that constantly rotates on two rollers. The rotation speed depends on the power of the device. The machine has high productivity and copes well with large volumes of sanding flat surfaces. Great for roughing and removing old paint.
2. Eccentric sander for rounded logs. The machine can work on both flat and curved surfaces. It is equipped with a round sole on which the abrasive is attached with Velcro. Used for fine sanding and polishing of wood.
3. The vibrating machine for grinding log frames has a rectangular base. The machine can work on a flat surface, and it is also convenient to process the corners of a log house. Features high quality grinding.

Drill for sanding wood

To sand a wooden house, you can use a regular drill. With this tool you can quite easily and efficiently perform a small amount of grinding work.

However, it is not recommended to use a drill for large areas. The drill is also equipped with grinding wheels, in the center of which there is a pin for installation in the chuck.

There are several types of drill attachments for grinding:

1. Flat, made in the form of a circle on which sanding paper is glued. The attachments are either rigid with Velcro or flexible with a rubber base.
2. Petal type, consisting of abrasive petals, similar to attachments on a grinder. You need to be careful when working with them. If handled carelessly, petal attachments can leave transverse lines on the wood that will appear through the varnish coating.
3. Drum nozzles are cylindrical in shape. The sanding belt is attached to the nozzle using a bolt. The drum is mainly used for grinding the ends of wooden workpieces.

Other grinding accessories

Another tool used for sanding wood is a Dremel. This is a mini universal device.

With its help, you can perform a wide variety of woodworking tasks with high precision: grinding, polishing, engraving, milling, drilling.

It is used extremely rarely for grinding large parts, but if you need to apply a drawing or engraving on a wooden surface, then it has no equal in this work.

When sanding wood with a grinder or drill, marks from the sanding discs often remain on the surface in the form of lines, grooves, and depressions.

Very often this happens due to inept handling of the tool and when working at high speeds.

It is quite difficult to get rid of these marks; you have to sand the surface again by hand.

For manual grinding, you can use a simple device that our ancestors used to grind - a sanding block.

It can be made from a rectangular wooden plank.

The board must be wrapped in sandpaper and secured with nails or screws.

During grinding, a lot of dust is generated, which settles not only on the surface, but also enters the respiratory system.

A log sanding mask, which is made from a special fabric that does not allow dust particles to pass through, will help protect your nose and mouth from dust.

Self-grinding mistakes

Most home craftsmen sand a wooden house with a household-grade grinder, which is not easy to use, has little power, and overheats quickly. A household appliance is not capable of sanding wood at a good quality level.

Professional equipment is expensive, so not everyone can afford it.

But even if you buy such a model, you need to know how to use it, otherwise, if handled ineptly, high-quality grinding will still not work.

Many people make the mistake of working at high speeds, pressing hard on the tool, which leads to damage to the surface.

The wrong choice of nozzles also does not lead to anything good. In the best case, the surface will simply be poorly polished, and in the worst case, cases of injury cannot be ruled out.

Attachments for processing stone surfaces

Polishing of marble and granite is done with professional-type attachments, which are used only by professionals. The main application is in processing, finishing polishing of marble monuments, the appearance is like a turtle.

It is necessary to carry out work at low speeds, so a grinder with adjustable shaft rotation speed is used. Polishing and processing of stone surfaces is carried out with different grain parameters, from 30 to 2000-3000. There is a special attachment marked BUFF, which allows you to polish products to a perfect shine and get a mirror effect.

Important aspects when working with an angle grinder

The appropriate attachments must be selected for each tool model . Before starting work, you must ensure that the disk is properly secured. The movement of the tool along the surface should be smooth. In this case there should be no vibration.

When sanding wood with an angle grinder, you should use thick discs. Due to the high rotation speed and the resulting load, the circle may break, which, in turn, leads to injury.

There are various types of assistive devices. Each specialist will be able to choose the tool that is right for him. Thanks to this, the work will be done efficiently, quickly, without using much effort.

Grinder cutting wheels for wood materials

Operating an angle grinder in tandem with a cutting disc for wood necessarily requires compliance with safety precautions. Work should be carried out in special protective clothing, and the workpiece to be cut should be firmly fixed in a vice or clamp

It is important to hold the tool with both hands to prevent it from being knocked out of your hands. Preference should be given to an angle grinder that has a speed regulator

Manufacturers produce discs for grinders on wood of four main types, which we will learn about in detail:

1. Circular or serrated - appeared the very first, but did not gain widespread popularity due to their kickback effect.
   The disk has an external (end) arrangement of large teeth. Manufacturers produce wood cutting discs for grinders with a maximum diameter of up to 180 mm. The teeth can be equipped with special brazings made of carbide materials. Although such circles are the most common, they are the most dangerous attachment in action. If possible, avoid using it. It should be noted that such discs can only be used on grinders if the tool is used as a stationary circular saw
2. Chain - they look like a disk, only along the outer circumference instead of teeth there is a chain, like on chainsaws.
   This type of attachment is safer and can be used to cut medium-density wood chips. With wheels of this type, the risk of jamming and kickback is minimized. This is achieved due to the special design of the nozzle, which is similar to a chainsaw bar. The circle consists of two parts, and there is a groove on the end side. The saw chain is located in this groove, moving due to the force of inertia. This design prevents the disk from jamming, and is thus a safer option compared to the first type. It is strictly contraindicated to saw wood with nails. At the same time, the teeth quickly become dull and fail
3. Universal - received this name due to the fact that it allows not only sawing wood, but also cutting metal, as well as making grooves.
   The universal type nozzle has the appearance of a regular steel disk, but with three additional teeth in the form of grooves. The teeth are tipped with hard metal, which increases the service life of the cutting attachment. The advantage of a universal cutting disc for an angle grinder lies in the fact that it is as safe as a chain wheel, and at the same time costs 2 times less. Produced by Graff, which is why it got the name “count”
4. With a tungsten carbide edge, manufacturers do not stop there and are constantly improving their products.
   Another type of cutting disc that is completely similar to a concrete cutting attachment. The only difference is that on the end part of the circle there is a tungsten carbide coating (diamond coatings are also found). The disk is equipped with slots with holes that serve to dissipate heat when working with dense materials, such as wood. Wheels with a tungsten carbide edge are effective not only for cutting wood, but also other materials - plastic, metal, etc. It is better not to use such an attachment for cutting one metal, because it will quickly fail. The wheel does an excellent job of sawing wood that contains nails, screws and other metal objects.

Now it’s not difficult to choose saw blades for wood for an angle grinder, knowing what types there are. For housework, it is recommended to use a wood saw blade with a universal or tungsten carbide edge. They are not only considered effective, but also safe. Circles with a saw chain are more expensive, but they are also safe when cutting wood with a grinder. The most dangerous are circles with teeth. They are recommended to be used only in situations where a stationary circular saw is made from an angle grinder.

On a note!

Wood processing also means its cutting (sawing). Sometimes, when manufacturing piece parts, you have to adjust them to the installation site even before you start grinding the sample. Some “craftsmen” (and there are many of them among friends and on the Internet) advise using circular saw blades for such operations. Strictly prohibited! Here are just the main reasons why this should not be done.

• “Bulgarian” is a high-speed machine. And although the metal from which the cutting discs are made is durable, it does not withstand this mode for long. More precisely, cutting edges (teeth), which are fixed by soldering. During intensive work, they fall off and fly apart, and with great speed. The consequences are easy to predict.
• Not all discs in size (primarily, outer diameter) are suitable for installation on angle grinders. This means you will have to dismantle the protective casing. The same thing - you can forget about employee safety.
• The structure of wood (even hardwood) is quite loose. Therefore, there is a high probability that the saw blade may jam due to constant vibration. How the “grinder” will behave in such a situation, given its power and speed, no one can predict. But it’s clear that it can easily escape from your hands.
• Constant changes in mode (for the same reason - the viscosity of lumber) lead to systematic overheating of the angle grinder engine. If used this way, the grinder will not last long.

That is why wood processing with its help is carried out only superficially - rough stripping, sanding, brushing. And for cutting you should use sawing tools and mechanisms (hacksaw, circular saw, electric jigsaw, and so on).

Working with an angle grinder for wood processing, what rules must be followed?

An angle grinder is used to process various materials, and no matter what is being processed, metal, plastic, concrete, brick or wood, safety precautions must be observed. Below is a list of recommendations that you need to heed when processing wood with an angle grinder in order to reduce the likelihood of injury.

1. Before installing the attachment into the tool spindle, it is necessary to disconnect the latter from the electrical network
2. Work must be carried out with a protective cover on the tool. Some craftsmen remove the casing not only in order to facilitate and speed up the work, but also in order to secure in the spindle a nozzle with a larger diameter than that intended by the manufacturer
3. You need to work with gloves, safety glasses, headphones and special work overalls
4. It is strictly contraindicated to use powerful angle grinders for wood processing. The best option is a tool for 125 mm circles
5. Do not use attachments with large teeth. The larger the teeth, the higher the likelihood of pinching and kickback.
6. The presence of a speed controller is a prerequisite if the tool is used for working with wood. If there is no speed regulator, you can use a special device to reduce the voltage
7. When working, the tool must be positioned strictly at right angles to the surface being cut. A slight tilt increases the load, and thereby increases the likelihood of it being torn out of the hands of the master
8. The tool start button must be controlled by the master, and it cannot be fixed, since if the tool is pulled out of the hands, the angle grinder will continue to work and can cause serious injuries
9. Do not use wood cutting attachments that have defects or signs of heavy wear.

In conclusion, it is necessary to summarize and note that an angle grinder is a universal tool that any home craftsman simply cannot do without. Regardless of what materials are processed by the tool, the main thing is that before purchasing the appropriate attachments, a person should be aware of the dangers of their use. If you do not have sufficient experience when working with angle grinders, it is better to use hand or specialized tools.

Choosing the right device

First you need to decide on the tool (grinder - the correct name is a chain angle grinder) with which you plan to cut the wood. It is known that discs are made to standard grinder sizes. The smallest diameter is 115 mm, but this tool is used in rare cases. A wide range of power tools on the market are designed to facilitate various types of manual labor. If specialized equipment is simply necessary when working in the professional sphere, then in everyday life it is not always rational to spend money on expensive hand tools.

To operate the machine with wood, you need a special drive . Abrasive, diamond, and carbide wheels are absolutely contraindicated for cutting. This will not help cope with the task, but rather will lead to destruction or overheating of the device.

When choosing woodworking universal accessories, you should know that there are not only cutting discs, but also grinding wheels. To clean the wood, use a circular saw blade. The working surface of such a device consists of several layers of sandpaper, which has varying degrees of roughness. The lower the roughness, the softer the grinding. Flap wheels allow for polishing that varies depending on the level of detail.

Grinding wheels and a milling cutter for an angle grinder must be of high quality, which affects not only the quality of the work performed, but also the safety of the technician. Processing wet wood is prohibited, as the result of such manipulations can be unpredictable.

For roughing operations, which are often used as initial processing, special cleaning agents are used. They are necessary in order to remove a layer of paint from a painted surface.

Milling with a grinder

Another dangerous tool, but permitted for use if precautions are taken, is a wood cutter for angle grinders. Using such a cutter you can make grooves, roughly level an edge, cut out bowls for a log house, and even saw workpieces

The design eliminates jamming and throwing of the tool on non-uniform wood. Before use, be sure to read the instructions, especially the sections about maximum speed and direction of rotation relative to the position of the angle grinder

Using such a cutter, you can make grooves, roughly level an edge, cut out bowls for a log house, and even saw workpieces. The design eliminates jamming and throwing of the tool on non-uniform wood. Before use, be sure to read the instructions, especially the sections about maximum speed and direction of rotation relative to the position of the angle grinder.

The range of cutters for an angle grinder is not inferior to the choice of attachments for a hand router. Of course, you won’t achieve the same exact processing, but you can choose a suitable attachment to give the workpiece any shape.

Safety Recommendations

You need to follow the rule: the larger the rasp disk, the lower the speed. In addition, manufacturers protect the user as much as possible by releasing discs with high (sometimes double) strength. But if the disk is used more than necessary, all these measures become meaningless.

Important tips on what to do:

• working with a protective casing;
• protect your face and head;
• check lumber for nails and screws;
• hold the device firmly by hand;
• use an additional handle (many people hold the device with one hand);
• Do not allow the instrument to heat up, avoiding the risk of smoke.

In addition, if there are no plans for large-scale work with an angle grinder, there is no need to buy a lot of disks “as a reserve” - since the humidity in the air begins to affect the bakelite. The bond strength is noticeably reduced. It is better to get the necessary wood discs for an angle grinder (grinder) immediately before work.

Metal brushes

Many craftsmen believe that metal brushes are used to remove rust and oxides only from steel products. In refutation of this fact, products made from brass wire are popular in wood processing. The relatively low price and increased service life make the brush a direct competitor to abrasive attachments.

The main purpose is to remove paint and varnish from the surface of the material. It should be understood that the top layer of paint can be removed by exposure to temperature; a brush is used when working in hard-to-reach places. It is also possible to brush wood using a grinder with a brush. The process involves artificial aging of surfaces in the production of unique interior products. The surface is processed with soft particles of wood, irregularities and temporary rings stand out against the general background.

Choosing a suitable grinder for cutting and processing wood

If you have to cut wood material, then you can do it with a grinder, but taking into account the correct choice of tool. Grinders are produced in different sizes and power, which determines the possibility of using attachments with a diameter of 115, 125, 150, 180 and 230 mm. An angle grinder for 115 mm cutting discs for wood is not the best solution. This is due to the following disadvantages:

• A small disk is installed on the tool, which is practically impossible to saw or process anything
• Inconvenience of working with a small grinder when processing large surfaces

The best solution for cutting wood with a grinder is a tool for circles with a diameter of 125 mm. It not only allows for efficient cutting of material, but is also considered to be as safe as possible. However, they are not so safe that they can be used even by beginners. It is better not to use tools with 150, 180 and 230 circles for cutting wood, since the high power of such grinders requires a lot of effort.

This is interesting!
An angle grinder is not a chainsaw or an electric saw, so it should not be used for cutting wood without proper skills.

The safest option is considered to be an angle grinder for wheels with a diameter of 125 mm. This is the type of machine that should be used when you need to use a tool for sawing woodworking materials. Before you buy an attachment with teeth for cutting wood, you need to take into account not only its outer diameter, but also its inner diameter - the mounting hole. For modern standard tools, discs with a diameter of 22.2 mm are available.

Important Tips

Finishing work begins only after the appropriate preliminary work has been completed on the workpiece. The result largely depends on which attachments are used to perform a given task. The grinder can be used as a cutter, polishing or grinding device. Thanks to attachments, the functionality of the equipment used is enhanced.

What kind of discs for a wood grinder may be required when carrying out polishing and grinding types of work? To successfully complete the task, you can use the following tools:

1. Cord brush. This tool is perfect for rough sanding solid wood. Possible leveling of the material is assumed, ensuring optimal shapes of the product.

   

2. End discs can be used to grind workpieces without much effort. This is mainly necessary when there are bevel cuts. The movement of the end disks is similar to the interaction of a saw with wood.

   

3. The flap sanding attachment is the most popular option among the consumables used. The characteristics of the tools determine the possible processing of any type of wood. When cleaning difficult wooden objects, you should use only wooden strips.
4. Felt wheels allow you to achieve minimal roughness on the workpiece. It is made from pressed wool, fine-wool, semi-coarse-wool and coarse-wool types. Using a felt working tool, high-quality processing of wood or other materials is achieved, and also gives the most smooth surface, similar to a mirror.
5. Chain discs for wood are one of the most sought-after tools, offering high performance and providing rough ways to process natural materials.

When choosing equipment, it is important to attach importance not only to the diameter, but also to each accompanying informative designation. The inscription allows you to determine the purpose of the tools and comply with operational requirements. Taking into account the markings on discs, wheels and attachments for angle grinders is a guaranteed successful result.

Modern types of grinders are convenient and effective models of the tool. For high-quality work, it is necessary to use special attachments and discs that will allow you to effectively process wood, metal and other types of materials.

What kind of circles are there for cutting wood?

Processing wood with a grinder is a safe process, unlike cutting. The process is very dangerous, the tool is not intended for cutting wood

Soft woods are processed with an angle grinder attachment with extreme caution, because the tool may jam and be torn out of your hands

The cutting process at high speeds implies a high temperature effect on the disc material, as a result of which it can simply shatter into small pieces.

Despite the fact that the grinder is not suitable for cutting wood products, manufacturers offer various cutting discs for use. It is recommended to use the grinder as a stationary station when sawing wood.

Circular saws

Circular saw attachments are dangerous when using an angle grinder. The diameter of the circle must be selected based on the parameters and dimensions of the tool in order to be able to use a protective casing.

There are more expensive modifications of circular nozzles; they have anti-jamming protection. The design has teeth set in different directions, smaller in size, the price of such a device is different, but you should not save on your health.

Chainsaws

The chain type of nozzles has a safer design. The sawing disc, which uses a chain from a chainsaw, eliminates jamming of the tool and reduces the risk of injury during work. The design has a system that allows the main element, which is attached to the angle grinder, to continue rotating, and the chain can remain stationary.

Chain disks come in many different modifications, with the help of which it is possible to carry out gardening work or use it for collecting small firewood. A disk of a chain design can be used instead of a peeling disk for cutting out cups in a log or removing a layer of bark.

Saws with few teeth

Increased safety when working with wood is achieved by using discs with a small number of teeth. Small discs usually have 3 teeth, those with a diameter of more than 180 mm - 4 teeth. This type of cutting disc is used for cutting both along and across the grain of wood. The saw wheel makes it possible to cut grooves and make tenons of various shapes.

It should be understood that when working with an angle grinder, you must adhere to technical regulations. There is no need to install larger diameter discs bypassing the protective casing; smaller discs can be used without loss of cutting properties.

Tungsten carbide discs

Tungsten carbide cutting discs have been produced relatively recently and are popular when working with an angle grinder. The universal tool is not equipped with teeth; instead of cutting elements, there are cutouts in the disk. The operation of the tool is most safe when cutting wood; it eliminates jamming when nails or thick rods of wood hit. The appearance is similar to a diamond blade for cutting concrete, the purpose is indicated on the packaging or instructions.

The price of such a disk is high, but it is justified. It is worth overpaying for a modified tool rather than going broke on the sad consequences of using a regular saw blade.

Main characteristics of cutting wheels

Depending on the material of production and design features, there are three main types of circles:

1. An abrasive disc
   for an angle grinder on wood, used when working with different surfaces. Depending on the thickness of the wheel, you will like the cutting and grinding wheel.
2. Diamond blade designed for working with stone, concrete and other building materials. Such circles are divided into segmented and solid. The first type, through better removal of the stump through the slots and more efficient cooling, ensures the highest productivity. Such discs are used when cutting thin metals.
3. An ordinary circle for a circular. But it should immediately be noted that it is not recommended to use it for cutting wood products without work experience, because there are many cases where, when clamping a disk in an array, people received quite serious injuries. If you are able to perform such work, it is better to use other equipment, for example a jigsaw, chainsaw, etc.

Types of discs for grinders

Today the entire range is divided into three main areas:

1. Saw blades. They resemble a regular saw, but are made from completely different materials. Until recently, such specimens could not be found, but now they are sold completely freely. The most preferred option is tungsten carbide.
2. Diamond coated disc. The most popular variety. In turn, it is divided into solid and segmented. Their scope of application is different, but they have a common feature - high-quality and accurate results of work on concrete, metal or stone.
3. Abrasive. Universal consumable, suitable for any type of surface. It cuts, grinds and polishes well.

Of the listed disks, the first and second are not suitable for wood. Natural wood has a very dense structure, and if you use a diamond disc, the grinder will overheat to the point of breaking.

The products also vary in diameter. The most practical ones have a diameter of 125 mm; in rare cases, a compact disk is needed - 115 mm. There are specimens up to 230 mm, but they are not suitable for wood. Their use may cause injury.

Abrasive discs for grinders

As mentioned earlier, abrasive wheels for grinders are divided into cutting wheels (up to 3 mm thick) and grinding wheels (thicker). Despite the fact that the classification is very conditional, there is another significant difference between the discs - the reinforcement of cutting wheels

It is usually carried out in 2 layers, and sanding in at least three.

Discs for milling and grinding on an angle grinder, purpose and types

The capabilities of angle grinders do not end with cutting, sanding and polishing wood. To expand the range of tool capabilities, manufacturers produce grinder attachments for milling and peeling wood materials. Stripping attachments are designed to remove bark and remove the paint layer from wooden surfaces. Peeling circles are available in different types, and differ in design, shape and purpose.

1. With an edge - their main purpose is to remove the top layer of wood, as well as grind the end part of wooden products.
   The applied edge made of carbide materials ensures a long service life of the nozzles. After processing wood with such attachments, you will need to additionally grind and polish the surface.
2. Studded - and they are divided into products with large and small spikes.
   Nozzles with small spikes are designed for removing the paint layer from the surface of wood, and with large spikes - for leveling. If a wooden floor has a defect in the form of a different arrangement of boards in height, then sanding discs with large spikes allow you to quickly and effectively smooth the surface
3. With a working part made of wire or brushes
   - such attachments are used not only for processing metal, but also wood. A cup-shaped disc with an angular wire arrangement is used to remove paint layers from large surfaces. A nozzle with an end wire arrangement is used to remove the paint layer in places with limited access, for example, in the grooves of processed wooden structures. Another type of attachment that craftsmen use to work with wood is a brush with a thin wire. Used for finishing roughing of wooden surfaces
4. A disc plane is an alternative replacement for a conventional manual or electric plane.
   The disadvantage of the first option is that it takes a lot of effort and time to complete the work. It is rational to buy an electric planer only when large volumes of work are being carried out to remove the surface layer. Special discs for grinders, replacing electric planers, came to the aid of the home craftsman. The attachment is a massive circle with three flat knives. It is intended for removing bark from a tree, and the end result is achieved very quickly. Dull knives can be sharpened

A special class of attachments for grinders are milling wheels. Special disks, driven by the spindle of the angle grinder, are used for sawing and cutting grooves of different widths. It is also worth noting that the use of milling attachments on an angle grinder is not safe

Every year the number of options for cutter wheels for grinders increases, but you need to work with such attachments with extreme caution. Let's look at the popular options for milling wheels for angle grinders:

1. The wheel rim has the appearance of a thickened circle with cone-shaped spikes located on the end part.
   Used for making grooves in wooden workpieces. The nozzle has teeth along the base, the main purpose of which is to obtain clean grooves without chips
2. Serrated toothed disc - used for making shallow rectangular grooves in woodworking materials
3. Toothed disc with additional tenons over the entire surface - allows you to make deep grooves in wood workpieces

The production of various attachments for grinders for the purpose of wood processing can significantly expand the functionality of an indispensable tool in the household. The grinder today replaces most hand and electric tools, so every master must have at least one type of this tool.

Grinding and polishing wheels for angle grinders - varieties

Working with wood involves not only cutting it, but also other types of processing. These types of work include polishing and grinding. Before you begin such work, you will need to prepare the material. The wood being processed must be dried, otherwise it will negatively affect the quality of the work. The following attachments are used for polishing and sanding wood with a grinder:

1. Petal wheels are a type of wheel for an angle grinder, consisting of a metal round base with glued strips of sandpaper around the circumference.
   Flap discs are suitable not only for sanding wooden surfaces, but also for polishing them. It is also important to understand that flap wheels are produced not only for processing wood, but also metal, and they differ in the type of abrasives used on sandpaper

   

2. End - needed to adjust the dimensions of the part.
   Sheets of sandpaper are glued to the end side of the disk, as in the photo below. The attachments work on the principle of a file. End discs are characterized by such a parameter as roughness, which depends on the nature of the work performed. The higher the roughness index (that is, the abrasive particles are small), the softer the grinding operations can be carried out with the nozzle. They are often used for restoring furniture and removing paintwork.

   

3. Polishing - for final processing of wooden surfaces.
   The products have different degrees of grain, as well as a simple design. The basis of the nozzle is a backing with a sticky part. Replaceable polishing attachments, which are made of soft abrasives, are attached to the Velcro part. The advantage of such products is that they can be quickly changed if necessary to switch to a different grain size. Polishing discs are used on an angle grinder to finish cleaning a wooden surface.

   

Depending on the type of wood work planned, it will not be difficult to choose the appropriate type of polishing or grinding attachment for an angle grinder.

Rough processing of wood using an angle grinder

However, it is possible to process wooden workpieces using an angle grinder. You just need to use special factory-made attachments and strictly follow safety precautions when working with an angle grinder.

Using an angle grinder as a plane

When roughing logs, for example for building a log house, special plane disks are used. This is a relatively safe way to process wood, subject to operating rules. It is a mechanized replacement for the carpenter's axe.

The nozzle is used without a protective casing, since it cannot be destroyed during operation. It is prohibited to use such a disc with it facing up. When working on a grinder, be sure to install a handle to hold the tool with both hands.

Since during stripping of wood, large chips fly out from the working area, it is necessary to have tight overalls and protect not only your eyes, but also your face. A positive side effect of this tool is that you can easily chop shavings and large sawdust for a home smokehouse.

Roughing discs

To remove bark from logs and give them the shape of a primary workpiece, there are special peeling attachments for angle grinders.

Using such a chain wheel, you can not only strip the trunk of bark and branches, but also give the workpiece the required shape for subsequent processing with a more precise tool. Such a device can easily replace an ax for cutting out a bowl in a log when building wooden log houses.

You can use this disk as a cutting wheel, but the cut will be torn and the loss of wood is too high; the thickness of the cut is several centimeters.

Diamond cutting wheels for grinders

Depending on their purpose, diamond discs can be divided into several types:

1. Concrete. Circles of this type can easily cope with monolithic structures, including concrete and reinforced structures.
2. Granite. Such discs are used when working with particularly hard stones.
3. Asphalt. Cutting wheels are best used when processing concrete and, accordingly, asphalt.
4. Construction Materials. Discs of this type can be used for cutting ceramics and bricks.

Diamond cutting wheels from some manufacturers are also color coded:

• Green is granite.
• Blue - concrete, marble.
• Yellow - plaster, tile.
• Gray - ceramics.

Segmented diamond cutting wheels are used for cutting materials using the dry method. When using solid discs, wet cutting (water cooling) is used. This is primarily due to the very high heating of the continuous surface of the cutting wheel.

There are models that have partial segmentation. These are so-called turbo discs, in which the slots are located in the body of the circle (they do not extend to the outer edge). Such products can be used at higher speeds than fully segmented ones.

So, by choosing the most suitable cutting disc for a wood grinder in all respects, you can perform any work efficiently and safely.
