How to choose an angle grinder? The recommendations given in the article will help you choose a tool.

What parameters are important when choosing an angle grinder?

Scratch disk size

The diameter of the disc is the main indicator of the grinder’s ability to perform certain operations.
The larger the size of the cutting wheel, the more powerful and faster the grinder should be. The diameter of the hole in the circle (fitting size) is standard: 22.2 mm. For angle grinders, five standard types of disks are produced, differing in size:

• Disc diameter 115 mm. Designed for cutting thin materials and for processing (grinding, polishing) small surfaces. The maximum cutting depth is about 30 mm.
• Disc with a diameter of 125 mm. One of the most popular sizes for household use. The cutting depth is about 40 mm. A large number of different attachments and additional equipment are available for this size.
• Disc with a diameter of 150 mm. Most often used in installation work as an auxiliary tool. Running size for cutting metal and plastic pipes for plumbing and electrical work.
• Disc with a diameter of 180 mm. Semi-professional size. Assumes work in non-stop mode. The cutting edge is 50 mm. Widely used in repair and construction work.
• Disc diameter 230 mm. Used in professional angle grinders with a power of up to 2.5 kW. It is practically not used for domestic needs - the devices are too bulky.

There are dozens of circles on sale for various types of work.

Angle grinder motor power

The greater the engine power, the greater the force the tool develops, the more dense materials it can cut. As power increases, the weight of the device increases. The industry produces tools with motors from 0.5 to 3 kW. For home and garden use, it is recommended to choose an angle grinder with a motor power of 0.8 to 1.2 kW. A more powerful mechanism is more difficult to hold in your hands and consumes more electricity during operation.

A professional tool is designed for long-term use and has a longer service life. If large-scale construction is planned at the dacha, cutting steel bars, assembling formwork, you can use a tool with a motor of up to 1.5 kW.

Disk rotation speed

In grinders, the rotation speed of the working shaft varies from 2.5 to 12 thousand revolutions per minute. The operating range is from 3000 to 6000 rpm. As a rule, the manufacturer sets the optimal rotation speed for his machine depending on the engine power, and sets this parameter at the design stage.

High-end angle grinders are equipped with a speed controller for the working shaft. This adjustment is especially important when changing discs frequently. For example, when a disk with a diameter of 230 mm rotates at a frequency of 10 thousand revolutions per minute, it will be very difficult to hold the tool in your hands.

Additional features

Additional features offered by the manufacturer will make working with the angle grinder convenient and safe:

• Smooth engine start. A very useful feature - the disc spins up to operating speed smoothly, without an “explosive” jerk at the start.
• Automatic disk balancing. Reduces vibration of the tool in your hands. It is especially helpful when using an unevenly worn disc.
• Number of handles. For household grinders, as a rule, there are two threaded holes and one handle that can be rearranged. This is very convenient if you need to change hands while working to get to a narrow place.
• Rotation speed adjustment. The electronic circuit maintains a constant speed of rotation of the motor shaft, regardless of the load on the disk. The work goes faster, the motor and gearbox will last longer.
• Availability of a dust protection system. An important function for working on concrete - the gearbox and shaft are protected from the ingress of cement particles, increasing the service life of the tool.
• Possibility of connecting a construction vacuum cleaner. Along with personal protective equipment - a respirator, goggles and gloves - it increases the comfort and safety of work. The workplace will remain clean.
• Fixing the start button. During long periods of operation, such as grinding or polishing, the operator does not need to hold the button pressed in the working position.
• Automatic power off. If the lights are turned off during operation, the machine de-energizes the tool so that it does not start on its own when the power supply is restored.

How to choose the right grinder for your home or cottage

In order to make the right choice of a grinding machine that meets all the necessary requirements, it is necessary to determine the tasks that will be assigned to it. Most importantly, determine what you will cut with the angle grinder and how often.

As practice shows, household grinders with a working disk size of 125 mm and a power of up to 1.5 kW are best suited for home and garden use. Such machines are light in weight and dimensions, easy to use, and equipped with additional capabilities. Many additional attachments have been produced for a circle diameter of 125 mm, turning the grinder into a universal tool.

The table shows the comparative characteristics of some brands of angle grinders from different companies represented on the market of electric tools.

Basic parameters of grinders

The main component of any power tool is the engine, and its main parameter is power. The higher this value, the easier it is for the angle grinder to cope with its responsibilities. Even under high loads, the electric motor must spin quickly. The recommended average value when working with various materials is at least 1-1.5 kW and above. At home, you can be content with a less powerful device.

The maximum diameter of the installed disk is important if you need to cut through the material to a greater depth. It should be noted that the larger the diameter of the circle, the more difficult it will be to work in awkward positions and it will not always be possible to crawl into some hard-to-reach places.

Quick-release nut

The number of revolutions of the circle depends on its diameter. Small circles spin up to 12 thousand revolutions per minute. Many professional grinders allow you to adjust that value. As a result, the user can configure the tool to perform various jobs:

• Cutting workpieces - maximum speed is required, this increases the speed of work and reduces the likelihood of the wheel biting
• Cleaning work - a rough (grinding) wheel is used. Very often, after welding products, it is necessary to smooth the seams, and after cutting the workpieces, to align the ends. The speed can be set to either maximum or average
• Polishing – this operation cannot be performed at high speeds: the surface of the product will burn. Typically, flap grinders or special polishing discs are used and the rotation speed is set to low.

Additional useful options and features:

• Quick-release nut – allows you to quickly change wheels without using a special wrench
• Soft start - available on most modern angle grinders. When turned on, the motor smoothly picks up speed and does not twitch in the owner’s hands
• Automatic shut-off is also present on almost all angle grinders. Even if the button is locked, if the tool falls to the ground, it will turn off
• Battery operation – the tool is autonomous, which allows you to work far from electrical sources
• Vibration-absorbing handle - makes it easier to work with an angle grinder during operation

Tips for choosing cutting blade size

It is the diameter of the disc that is the key factor that determines the scope of work performed by the tool. It is worth noting that the seat diameter for circles has a standard size of 22.2 mm. But, the larger the diameter of the cutting wheel, the higher the rotation speed and power of the grinder. The minimum diameter is 115 mm, the maximum possible is 230 mm.

The diameter of the disc is selected depending on the thickness that will need to be cut. Based on the fact that not the entire part of the circle, but only the part protruding beyond the tool, can be used as a working part, it is necessary to pay attention to the size of the body. For example, if the case is about 60 mm wide, then when using a 125 mm disk it is easy to understand that only half of its surface will work. That is, it will be possible to cut through material no more than 35 mm thick, and in reality even less - 30 mm. After some time, the cutting surface of the disc will wear off, which will significantly reduce this indicator. Using these simple calculations, the required disk size is selected. But it is strongly recommended not to use circles with a larger diameter than allowed by the technical documentation.

To make it easier for you to navigate, let’s look at the types of grinders in more detail, based on the size of the disc:

• An angle grinder of 115 mm is the minimum size for the simplest work. It is most often used for grinding, since cutting at this size is very inconvenient. A smaller diameter means less weight, which means less power. The weight is in the range of 1.5-3 kg, and the power is no more than 1000 W. But the “small” grinder has a maximum speed of 10-11 thousand rpm. It is possible to grip with both one and two hands. The size of the tool does not affect the price, and such a compact tool can have low cost, and vice versa. There are models equipped with many additional functions for professional use.
• 125 mm grinder is the most popular model. It has sufficient power, optimal weight and size for ease of use, and an affordable price. Any store has the most extensive selection of grinding or cutting wheels with a diameter of exactly 125 mm. This is the optimal tool for home use if you do not plan to cut too thick parts.
• Bulgarian on 150 mm – unlike the previous model, it is not in such demand, although it is an excellent alternative option for home use if you need a model that is not small, but not large either. It is convenient to perform both grinding and cutting work. But many argue that a more convenient solution would be to buy separately a small one – 125 mm and a large one – 180 mm. This tool has an average power of 1000-1500 W, an average rotation speed of 8-10 thousand rpm and an average weight of 3-5 kg. "Golden mean" for home craftsmen.

• 180 mm grinder is a suitable option for construction work. The depth of the cut will make it easy to cut bricks (however, you still need to cut on both sides), thick pipes and other elements. This means that doing smaller jobs with such a tool may not be entirely convenient.
• 230 mm angle grinder is the maximum provided by the manufacturers. They call her the “big” grinder. It has a more significant weight - 5-8 kg, a powerful engine - 1500-2000 W, speed - 6-8 thousand rpm. They are equipped with two handles - rear stationary and side with the ability to be installed on different sides of the body. They are expensive, which is justified by the number of built-in functions. With its help, they perform rough work where the use of force is necessary, for example, cutting metal pipes, gating walls for wiring, etc. Such models are absolutely unsuitable for small jobs; even grinding seems unlikely. But for major repairs or construction work, they will come in handy.

Having analyzed the five possible sizes of this tool, it is clear that each has its own advantages and disadvantages. If you are engaged in construction work at a professional level, then the optimal solution for you would be to purchase two grinders. Small – 125 mm for precision work and medium – 180 mm. If you have to do repairs or construction, then a 150 or 180 mm tool is suitable.

Safety precautions when working with an angle grinder

A priori, repair equipment cannot be absolutely safe: therefore, before starting operation, you must read the instructions in order to avoid unpleasant and even traumatic situations.

The most common cases are:

• Electric shock;
• Injuries from parts of the treated surface flying out from under the tool disk;
• Dust getting into the eyes, respiratory system, skin;
• Disk rupture as a result of it getting stuck in the surface being processed or strong vibrations of the angle grinder.

When working with an angle grinder, it is necessary to protect your face and body: be sure to wear a protective mask, headgear, thick gloves, clothing and shoes made of rough materials. This way you can avoid injuries from particles of the material being processed, or hair or clothing getting caught in the device.

The second thing you should pay attention to is the cord; it cannot come into contact with hot objects, chemicals or petroleum products

List of things you should absolutely not do:

1. Change the disk without disconnecting the device from the network;
2. Use an angle grinder without a disc guard;
3. Allow the cable to bend closer than 5 cm from the device body;
4. Carry the grinder by the cable;
5. Process materials containing asbestos, chalk or abrasive substances;
6. Operate angle grinders in rooms with high humidity or in rooms with the risk of explosions;
7. Work with replacement discs that have expired;
8. Operate a device with defects;
9. Use angle grinders on unstable surfaces, inside power sources;
10. Leave the device plugged in unattended.

If you follow basic safety rules, working with an angle grinder will only bring positive results and will not harm the health of the owner or his family.

Angle Grinder Safety

For many craftsmen, it will probably be news that in the sad statistics of accidents when working with power tools, it is “grinders” that confidently hold the first place. And the point here is not at all about the increased danger of the tool - the cause of most accidents is non-compliance with safety precautions.

To avoid accidents, you should firmly adhere to the rules of working with angle grinders and pay attention to a number of options:

Starting current limitation

provides a gradual increase in speed when the grinder is turned on, reducing the load on the engine. This not only allows you to extend the “lifetime” of the tool, but also increases its safety - an angle grinder with a soft start will not twitch or pull out of your hands when turned on.

Overload protection

reduces the load on the engine when the nozzle jams. This option can prevent engine damage and avoid excessive jerking when jammed. Overload protection can be implemented in various ways: mechanically, using a coupling or other design; and electrically, by monitoring current consumption.

Engine brake

speeds up the disk stop after turning off the tool, which increases its safety. Some professional models are equipped with a release clutch and a disc brake that stops the disc immediately after turning off the angle grinder.

Only the future owner can choose the instrument for himself - excessive weight will affect the duration of the procedures performed, and the lack of protective mechanisms can cause injuries in places remote from the hospital: at the dacha or in the village, etc.

When purchasing, you should pay attention to the year of manufacture of the equipment and markings so as not to purchase an outdated model.

Angle Grinder Selection Options

If you are looking for a universal tool for everyday use, pay attention to models with a maximum diameter of 125 mm - they are light, compact, and it is not a problem for them to find any type of attachment.

For construction work, for frequent cutting of pipes and rolled metal, a “grinder” with a maximum disc size of 180 mm would be a good choice.

When working with metal structures and thick-walled large-diameter pipes, you may need a tool with a large disk size - from 230 mm.

Rating of Bulgarians by reliability

Taking into account the characteristics described above, it becomes clear that choosing a really good angle grinder among the variety of offers is not so easy, because depending on the tasks, it must meet various requirements.

A powerful, heavy professional grinder cannot be considered the best model, nor can a tool intended for rare home use. It is imperative to take into account the operating features of each device, without forgetting the cost. This parameter can also help the buyer in choosing the ideal model for himself.

Many buyers, even after familiarizing themselves with the key characteristics that should be taken into account when choosing, often turn to reviews from real users, because their opinion is much more objective than the ratings of popular models. Based on them, we can distinguish the following types of grinders that our compatriots buy more often than others:

1. Metabo WEV 10−125 Quick;
2. Makita BGA452RFE;
3. Bosch GWS 12−125 CIE;

Metabo WEV 10−125 Quick

Criteria for choosing a good angle grinder

Before choosing an angle grinder, you should familiarize yourself with the main characteristics

When choosing, they take into account: suitability for home use, diameter of the circle, speed and intensity indicators, availability of types of protection. To choose the optimal, cost-effective model, you need to find out the amount of electricity consumption

Discs are consumables. They come in different diameters: 115, 125, 150, 180 and 230 mm. The latter can cut thick metal.

Engine power

The continuous stable operation of the tool depends on this indicator. For use in the country and at home, a cordless angle grinder with a power of 600 to 900 watts is suitable. If you have a complex and lengthy amount of work to do, you need to choose an angle grinder, the power of which starts from 1.5 kW.

For each specific job, a specific disk size is used

Disk rotation speed

This indicator influences the choice of disks. Speed ​​is directly related to the power of the grinder and the largest diameter of the disc. Small angle grinders have a power of 600-1100 W and a spindle speed of 10000-11000 rpm, large ones - 2500 W and 7000 rpm.

Low-speed discs cannot be installed on a high-speed grinder. A 230 mm wheel will not have enough safety margin if the speed is exceeded. If you install a 7000 rpm disk on a tool with 10,000 rpm, then due to the development of a speed not intended for it, it will shatter into pieces.

Speed ​​adjustment

In good grinders, equipped with a special regulator, you can control the operating modes.

This option is needed when:

• Use of diamond-coated discs. Thanks to this function, overheating and damage will be avoided. Workpieces are processed at low speeds.
• Replacing a circle of one size with another. Here you have to adjust the speed.
• cutting fragile materials.
• Stone processing. For each type you need to select your own speed.

Unintentional start protection

It is a device that blocks pressing the start button. To start the engine, it is first unlocked. If there is such an option, then in any unforeseen situation, the button will not be pressed.

Motor overload protection system

During operation of the angle grinder, the electrical wire experiences an unstable load. At some points it is significantly higher than calculated. In order to protect the motor from overload, the tool is equipped with a special system. Its task is to forcefully stop the supply of electricity.

There are 2 ways to protect angle grinders from overheating: by temperature and current. In models with current protection, the device turns off when the electronic module detects exceeding the limit values. In other devices, a temperature sensor is installed on the motor. When the value goes beyond certain values, it breaks the power circuit.

Jam protection

Thanks to the option, a running engine instantly stops. If the blade accidentally jams during cutting, the operator is protected from kickback.

Smooth start

The function increases the number of rotations of the circle gradually. This helps to reduce the load on the network when starting the grinder.

Soft start block for angle grinders

Restart protection

This option is useful in case of a power outage. Even if the start button is activated, the angle grinder will not turn on when the light appears.

Dust removal system

Expensive models are equipped with it; inexpensive instruments do not have such a system. Thanks to its presence, the operator does not need to look for how to connect a vacuum cleaner to clean the dust that is generated during operation.

Operating principle and scope

An angle grinder is an electric hand tool that is designed for cutting, sanding and grinding materials such as various types of stone, including concrete, metal, wood and others. The construction of an angle grinder is not particularly complicated. However, it is necessary to navigate this issue in order to be able to carry out repairs or preventive cleaning yourself. The durable plastic case contains the following basic elements :

• Speed ​​control wheel;
• Engine;
• Start button
• Frame;
• Quick disk replacement button:
• Safety coupling;
• Protective cover;
• Working disk clamp nut;
• Gear housing;

The principle of operation itself comes down to the conversion of torque, which comes from a spindle connected to the engine via a gear drive. It is to the spindle that various attachments necessary for this or that type of work are attached. The body of the tool is made of high-strength plastic that can withstand impacts. Simply by using different types of attachments, or rather, different types of abrasive wheels, you can perform completely different tasks, which significantly increases the scope of application of this tool.

The grinder is used when necessary:

• Trim or cut out tiles;
• Cut metal sheets or rods;
• Cut grooves in a brick or concrete wall for laying electrical wiring or water pipes;
• Remove rust from a car body or a layer of old paint;
• Sand wooden or metal surfaces to a high degree of smoothness;
• Clean the welds;
• Dull sharp edges with chamfers.

Its engine operates at a power of 2.6 kW and the speed is 6600 per minute. The handle here is rotatable, and it can be placed in 7 positions.

Along with the advantages, there is also one negative point - the high cost, which is not affordable for every person, although it is intended more for professionals.

Power consumption

From 700 to 2600 Watts.

The power of an angle grinder shows how productive the tool is and how well it carries the load. If the motor is weak, then you need to cut or grind carefully, without strong pressure, otherwise you can overload and overheat the motor. A powerful grinder can be loaded to its full capacity (without fanaticism, of course). This will allow you to complete the task faster. Small angle grinders have a power from 700 to 1500 W, large ones - from 2000 to 2600 W. At the same time, the most powerful (in their class) angle grinders are equipped with a large number of options. Please note that the specifications indicate the watts consumed. The power output will be significantly lower.
