Universal tools include angle grinders with adjustable spindle speed. They are suitable for cutting workpieces, fine grinding, and cleaning surfaces from rust or scale. The grinder is used to work with materials such as wood, metal, stone, plastic, concrete. The best foreign and Russian manufacturers offer their products to domestic consumers. Sanders differ not only in price, but in performance, level of safety, and ease of use. The choice of tool should be approached responsibly; expert advice will help you find a reliable and durable model.

Recommendations for choosing an angle grinder

Power type

. The most popular models in everyday life, in warehouses and construction sites are electric angle grinders. There are two varieties in this category.

1. The network tool still occupies a leading position in terms of sales volume. The main reasons for its popularity are the wide price range, variety of models, reliability and high performance. The only drawback will be the connection to the outlet.
2. Cordless angle grinders are not yet as popular as screwdrivers or saws. Although they are superior to their networked counterparts in maneuverability and mobility, the operating time on a full battery charge is limited to 2-3 hours. In addition, the battery makes the structure heavier.

Speed ​​adjustment.

When choosing an angle grinder, it is important to determine the speed adjustment range for yourself. It all depends on the specifics of the operations that will be performed using the tool.

1. If the grinder will cut metal, then the optimal speed range should range from 7000 to 11000 rpm.
2. It is better to cut stone or concrete with a frequency of 5000-7000 rpm.
3. It is more convenient to sand wood at a speed of 2000-4000 rpm.
4. It is better to process metal surfaces with a frequency of 2000-3000 rpm.

Specifications

. The grinder has several important parameters that potential buyers should pay attention to.

1. The set of characteristics depends on the maximum diameter of the equipment (disc or circle). In everyday life, a compact tool with a disk size of 125 or 150 mm is most often used. The larger the equipment is installed, the more powerful the motor should be.
2. An important characteristic of a network angle grinder is power. It is expressed in watts and varies from 800 to 2000 watts. The higher the indicator, the longer the tool can work without overheating.
3. The strength of a cordless sander depends on the parameters of the battery. It is considered optimal to use 18-volt current sources with a capacity of 4-5 Ah.

Equipment.

To increase operator safety, extend tool life and comfortable operation, angle grinders are equipped with a number of options.

1. Powerful models are equipped with a soft start, thanks to which the unit starts up softly.
2. When it is important to adhere to a given speed limit, a speed stabilization system under load will be useful.
3. A serious danger for the operator is the jamming or snagging of the equipment. The problem is solved by installing an electronic clutch.
4. To prevent accidental activation of the tool, a double trigger button is installed.
5. Keyless replacement of equipment will be relevant when frequently replacing discs or wheels.

Only 12 variable speed angle grinders made it into our review. You can purchase them in specialized stores across the country. The editors of simplerule magazine distributed positions based on the conclusions of experts. At the same time, the reviews of Russian masters were taken into account.

Which grinder to choose

When buying an angle grinder, you need to look at the following parameters:

• rotational speed;
• availability of additional functions;
• power;
• disk sizes that fit the device.

An indispensable device in everyday life is a grinding machine. It is compact in size and very easy to work with. It will only take 15 minutes for a person who has never worked with an angle grinder to fully master the principle of working with it.

If you need to buy a household grinder, then you should take into account the fact that it is not intended for daily and long-term use. The technical performance of such devices is much lower than that of a professional device, which can be used for a very long time without overheating. Professional angle grinders are also equipped with special brass inserts, as well as a metal body.

This is necessary in order to use the grinder in extreme conditions, such as:

• excavation;
• pipeline laying.

For such work, it is necessary to purchase a tool that will be maximally protected from moisture and dust. That is why in no case should you use ordinary household grinders in such work, since they will very soon fail.

Rating of the best angle grinders with speed control

What to consider when purchasing

If you want to buy a grinding machine, you should first study all the technical indicators of the model you like. It is best to buy a device with a soft start. In this way, you can protect yourself and others from possible jerks while working with a power tool.

You need to know that when the speed decreases during operation, the load on the machine system increases. In such situations, overheating will occur. You need to buy an angle grinder that is equipped with modern sensors, as well as a speed controller for overload and overheating. The more complex the device, the higher its class, and accordingly, the more expensive it is. But at the same time, the amount of work that can be performed using such equipment will also increase.

Under no circumstances buy the first car you come across. You must first decide what tasks will be set for it. If you need to work with equipment for a very long time, then it is advisable to buy professional equipment that will not overheat with a lot of work.

An angle grinder with variable speed control is perfect for both production and home use. In skillful hands, the device can perform a large number of jobs. You just need to choose the right angle grinder with speed control. Therefore, always read the instructions and all the characteristics before purchasing.

Types of angle grinders

Angle grinders are one of the most popular types of power tools, both at home and in production. In terms of popularity among buyers, they are second only to electric drills and screwdrivers. Every man who does anything with his own hands is simply obliged to have a grinder in his arsenal. This fairly versatile power tool is capable of performing a number of jobs, including: cutting, grinding, and cleaning various materials. The grinder can handle with equal success: stone, wood, metal, plastic, slate, drywall, etc. That is, almost any material used in construction.

Unlike some other power tools, grinders are not particularly diverse. This is explained by the rather simple design of an angle grinder, consisting of a cylinder-shaped body, often with a side handle (less often with two), inside which there is a universal commutator motor. On top of the body there is a attachment point for attachments, thanks to a large selection of which the tool is famous for its versatility. Therefore, answering the question of which grinder to choose is not so difficult, because you have to choose, first of all, between different manufacturers and the power of the tool. Although angle grinders can be divided, quite roughly, into two groups.

Household

Obviously, this group includes a tool that is not intended for intensive work in industrial production conditions. Household grinders have less power and size. The last criterion is especially important when you have to decide how to choose an angle grinder for your home, since the size of the attachment attachment directly determines what diameter of the circle is suitable for the selected tool. So, for home, not too frequent use, a grinder with a minimum circle diameter of 115 mm is quite suitable, but a professional will probably choose a large tool (up to 230 mm), not only because of its power, but also because those who came to change Nozzles with a larger diameter will fail much less often.

In addition, household angle grinders are not characterized by high productivity, since due to a lack of power and design simplicity, they quickly begin to overheat and when working with them, you have to take frequent pauses to cool them down.

Professional

How to choose an angle grinder for work on a construction site or for industrial production? The simplest answer is to choose a large angle grinder. The rated power of such a tool starts from 1.5 kW, which allows it to be used in intensive mode for a long time. Overheating of large and powerful angle grinders, unlike household tools, is practically excluded. In addition, professional angle grinders have higher wear resistance of parts, which significantly increases the service life of the power tool.

The body of the professional angle grinder is made of high-strength materials, which well protects the tool from various types of mechanical damage. Finally, the professional tool has more advanced features that make it easier to use. But professional-type angle grinders also have significant disadvantages. Firstly, it is heavy, which is due to both the large size and the presence of additional components. And secondly, the price of a professional tool can be several times higher than the price of an angle grinder for household use.

Grinders also differ in the presence of one or two handles. Everything is clear here. Large and heavy angle grinders with a power of more than 2 kW are equipped with two handles. For household mobile grinders, one handle is enough to hold them securely during operation.

The best cordless angle grinders with speed control

When you have to work away from the electrical network, cordless angle grinders come to the rescue. They are also used in cases where it is necessary to make a couple of cuts. Several tools have caught the attention of experts.
