How to choose an angle grinder. Options

If you want your tool, in addition to the obligatory on / off function, to have additional features, and you are ready to fork out for this, then it will be useful to know before choosing an angle grinder, which tool manufacturers can please you by making work with it more comfortable and safe.

Soft start system. This option allows you to slowly pick up speed by balancing the inrush current. This compensates for the current surge when the instrument is turned on. Smooth start-up not only prolongs the service life of the angle grinder, but also protects other devices connected to the network from power surges that could damage them.
Control of the speed of the disk. A very useful function, especially when sanding. This system helps to select the optimal rotation of the nozzle, which significantly extends the life of consumables and saves energy.
Anti-recycle system. Avoids incidents where suddenly turning on the tool after being forgotten to turn it off, for example, due to a temporary power outage, could result in serious injury. The presence of the system requires the obligatory pressing of the start button to re-enable the angle grinder.
Automatic disc balancing system. With uneven wear of the disc, vibration of the tool occurs, which leads to rapid wear of the spindle parts. To avoid such undesirable consequences, a balancing system is installed on some models of angle grinders, which quickly and effectively stabilizes vibration.
Speed control. It is also an extremely useful function and before choosing an angle grinder, an angle grinder for the home, it is advisable to make sure it is available. Setting the optimal number of revolutions before each job and for different types of materials to be processed means not only to reduce wear of the nozzle and avoid overheating of the tool, but also to protect yourself from possible injuries in the event of a sudden destruction of a circle that cannot withstand too high revolutions. In addition, with some types of processed material, it is undesirable to overheat its surface and reducing the speed of the nozzle simply and effectively solves this problem.
Anti-jamming system. Automatically shuts off the tool in case of jamming of the nozzle, which not only protects the wheel from destruction, but also prevents the brushes of the electric motor from burning.
Quick disk change. Some models are equipped with an improved attachment attachment design, which makes it possible to change wheels faster.

Household

Obviously, this group includes a tool that is not intended for intensive work in industrial conditions. Household angle grinders have less power and dimensions. The last criterion is especially important when it is necessary to decide how to choose an angle grinder for the home, since the size of the attachment point for the attachments directly depends on which circle diameter is suitable for the selected tool. So, for home, not too frequent use, an angle grinder with a minimum circle diameter of 115 mm is quite suitable, but a professional will certainly choose a large tool (up to 230 mm), not only because of its power, but also because to change worn-out nozzles of a larger diameter will have to be much less often.

In addition, household angle grinders do not differ in high productivity, since due to the lack of power and structural simplicity, they quickly begin to overheat and when working with them you have to make frequent pauses to cool them down.

Types of angle grinder

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

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

Nozzles

The scope of its application directly depends on which nozzle is installed on the angle grinder. For each type of processed material and the nature of the work performed, there are different attachments. Their main types are discs or circles and various kinds of brushes, fixed perpendicular to the body of the angle grinder on the spindle using a threaded connection. Both those and others have a fairly large number of modifications and types. So, the circles differ from each other primarily by the type of materials being processed.

There are different circles for: steel, stone, paving and ceramic tiles, various alloys, and so on. Although there are universal cut-off wheels that apply, if not to all, then to most materials. Cutting wheels also differ in diameter, as mentioned above, as well as in thickness. In addition to cut-off wheels, there are flap discs and abrasive discs that require a separate attachment or flange. In the latter case, the nozzle is screwed to the spindle, and already to it, with the help of the so-called velcro, is attached a grinding disc.

The brushes used on angle grinders also depend on the material being processed. So, you can distinguish brushes, the bristles of which are made of steel, used mainly for cleaning rust and paint from metal surfaces. Brass brushes have approximately the same scope. They are softer than steel and fail faster, but they do not spark and leave less scratches on the metal surface. There are brushes with nylon bristles. Their area of application is mainly wood. In addition, the brushes are divided into bowl and disc.

Models and manufacturers

How to choose an angle grinder angle grinder from a huge number of different manufacturers? First of all, it should be remembered that any power tool is equipment that can threaten the life and health of the user due to the high voltage used as a power source.

In addition, angle grinders have open, high-speed rotating parts that can also cause injury to a person. Therefore, the choice of the manufacturer should be approached with all responsibility, you should not tempt fate and buy a tool made by someone who knows where and who knows who, from random sellers, even if the offered price seems very attractive. To understand which angle grinder to choose for the home, it is best to look at the products of the domestic company “Interskol”, whose tools are of high quality, and a wide range of models will give the best possible answer to the question “how to choose an angle grinder“.

Professional

How to choose an angle grinder for construction site or industrial production? The simplest answer is to choose an oversized 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 impossible. In addition, the professional angle grinder has a higher wear resistance of the parts, which significantly increases the service life of the power tool.

The body of a 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 work with. But the professional-type angle grinder also has significant drawbacks. Firstly, it is heavy, which is associated with both the large size and the presence of additional nodes. And secondly, the price of a professional tool can be many times higher than the price of an angle grinder for household use.

The angle grinder is also distinguished by 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 angle grinders, one handle is enough to hold them securely during operation.

Choosing an angle grinder for the home. Main criteria

What characteristics of an angle grinder should you pay attention to before buying? Obviously, first of all, the choice will depend on the type of proposed work. If it is not clearly clear which angle grinder to choose for the home, that is, to choose a universal tool, then you should pay attention to the following characteristics:

Diameter of the applied nozzle. As noted above, a fairly simple selection criterion is used here. the more powerful the tool, the larger the nozzle. In turn, it is obvious that the larger the diameter, for example, of a circle for cutting metal, the thicker the workpiece you can cut.
Rated power. Here the choice depends on the field of application of the tool. The range of this parameter is quite extensive: from 0.6 to 2.7 kW. So if you are buying an angle grinder for simple sanding of wood surfaces, for example, then there is no point in buying a large, powerful tool. Firstly, because it costs much more, and secondly, a heavy professional tool will not be able to reveal its capabilities. And in this case, it will be inconvenient to manipulate a large, heavy apparatus, which will only lead to quick fatigue. Conversely, if you are going to cut concrete or metal workpieces, then you will need a powerful angle grinder with a large circle diameter.
Rotational speed. The spindle speed range of the angle grinder ranges from 2800 to 11000 rpm. In more expensive models, it is possible to adjust the speed, and if there is no such regulator on the instrument, then the principle works: the larger the disc, the lower the speed. The fact is that at a high speed of rotation of the nozzle, its destruction is quite likely, which can lead to injury.
Additional functions. We will dwell on this selection criterion in more detail in order to understand which angle grinder is better and to make an informed choice.

Choosing an angle grinder for work and home

Choosing an angle grinder does not at all mean finding a life partner from a solar angle grinder or voting for an angle grinder beauty at the next beauty contest, and this is how a foreigner can understand the intention of a person from a post-Soviet country if he translates this phrase literally from Russian. After all, he is unaware that in the countries of the former Soviet Union, choosing an angle grinder means choosing an angle grinder or an angle grinder, which it is, in fact.

Mains powered

Networked are some of the most popular power tool options. In this case, the angle grinder is powered by a socket.

Pros:

variety in terms of dimensions, capacities allows you to supply abrasive wheels of all sizes;
low, in comparison with other types of angle grinder, price;
lighter than other models, weight;
many attachments for different jobs.

Possible complaints:

if the electricity is turned off, it will not work;
the user’s movement is limited by the length of the wire;
failures with voltage drops.

What is an angle grinder

angle grinder is the popular name for an angle grinder (angle grinder). It can be used to cut materials (metal, brick and stone, wood), grind and clean surfaces.
It is named angular due to the fact that the axes of the motor and the grinding disk are placed at an angle of 90 ° in relation to each other. This is realized thanks to the gear train. This arrangement is the main difference between the device and straight grinders, where the wheel is on the same axis with the engine.

How to choose an angle grinder for home use. 10 main criteria

Need a quality angle grinder for home use? How to find a good option for your home and not overpay, the article suggests.

Nut retainer

To change a worn circle, you must first fix the spindle, and then unscrew the nut with a wrench.

If the nozzle rarely changes, you can do with the standard method described above. But if the work is different and it often needs to be replaced, then buying a device with an SDS nut, which is unclenched without an additional tool: replacing a disc takes a few seconds.

Gasoline

Devices that run on gasoline are large in size, since the design, in addition to the engine, is also equipped with a fuel tank. To hold such a massive device, manufacturers supplement the tool with a frame-handle, an additional handle. This type of angle grinder, like the previous one, makes it possible to cut concrete, stone in places where power is not supplied.

Note: To cut hard material, you need a special circle.

Why are they good:

Impressive power figures.
The ability to install large drives.
High productivity: cutting large structures takes less time.
Autonomy.
The possibility of refueling allows you to work for a long time.
Often supplied with a stand, which makes it possible to use the device as a cutting machine.

Disadvantages:

additional fuel costs;
loud noise;
harm to the environment;
work will have to be stopped from time to time to cool the engine.

Disc diameter

The abrasive wheel cuts, is responsible for cleaning and grinding. The front of work available to the tool depends not only on the material for making the circle, but also on its size.

Important: when choosing an accessory, you need to take into account that it is capable of cutting to a depth of no more than ⅓-of its diameter.

When choosing, it should be borne in mind that a small diameter wheel is suitable for large angle grinders, but not vice versa: large sanding discs are not compatible with compact angle grinders.

All discs can be divided into five classes. The features of each of them are in the table.

Types of angle grinder

In addition to the fact that the angle grinder is divided into household and professional, the angle grinder is distinguished by the principle of operation. The difference between the two is only in what is inside and in the power source. Given these features, you can choose the appropriate option for certain operating conditions.

What is an angle grinder for: what you can do an angle grinder

Its main purpose. cutting various durable materials. metal, concrete, stone and the like, as well as their cleaning, roughing and grinding. The angle grinder is often used during construction work. If necessary and in the absence of other special devices, the angle grinder can also be used for sharpening cutting tools. knives, axes, chisels, etc.

Recent replenishment. cordless angle grinder. They will allow you to work comfortably in any conditions, and a powerful engine is capable of working with high torque.

The entire line of power tools comes with a three-year warranty.

Attachments and additional functions angle grinder

In fact, an angle grinder can have a ton of features that make it easier to work with. But what are they? Among the accessories for the angle grinder and the additional functions of the tool, the following can be distinguished:

Ergonomic body and handles

Since the angle grinder is a hand-held tool, comfort and weight are not the last factors when choosing. Particular attention should be paid to the convenience of the handle-holder, because it is with its help that you will control the process of cutting and grinding. Also, the handle will take on most of the vibration, so many manufacturers are trying to make it anti-vibration.

How to choose an angle grinder: an angle grinder for home and work

An angle grinder (angle grinder) is a hand-held electric tool that is designed for cutting, cleaning and grinding hard materials such as metals, stone, concrete, etc.

The name “angle grinder” stuck to the tool in connection with the first models of angle grinder, which were imported to the USSR from the angle grinder. Abroad, the grinder is called “flex” after one of the first manufacturers.

Still, how to choose an angle grinder? We will analyze it in more detail in this article.

Choosing an angle grinder for home use

The simple household angle grinder for home use is designed for infrequent, short-term and low-effort use. As a rule, the choice of an angle grinder for home use does not cause difficulties, because they differ in minimal characteristics:

Affordable price;
Lightweight body, weight up to 2.5 kg;
The tool does not overload the power supply;
The minimum power is 500-900 W;
Minimum size of replacement discs 115. 125 mm for simple jobs.

You can find a suitable model for home use on the website dnipro-m.ua.

What is the RPM of an angle grinder: rotation speed

Most angle grinders allow you to adjust the spindle speed depending on the size of the disc used. For this, a special regulator is used, through which the speed of the angle grinder increases or decreases. Note that the rotational speed of large-diameter discs is lower than that of their smaller counterparts (the logic is extremely simple: the higher the disc diameter, the larger the circumference, and the longer the length of the working surface of the tool the workpiece will come into contact with during one spindle revolution).

Dust removal system

The function, thanks to which the operator does not have to think about how to screw a construction vacuum cleaner to the tool, its cable is simply connected to a special nozzle on the tool. This add-on will be extremely useful for professional builders. Correct dust removal during work will save the angle grinder itself, the cutting disc (will increase its service life by at least two times), improve the convenience of work and protect your lungs.

How To Choose an Angle Grinder

Pneumatic angle grinders

Although electric angle grinders are in the first place in popularity, pneumatic angle grinders are also in demand.

In order for the tool to function as efficiently as possible, it is necessary to choose a high-quality compressor for it. It is selected depending on the pressure and efficiency indicators. The efficiency of machine operation depends directly on the quality of the compressor. The peculiarities of interaction with a pneumatic drive include the fact that the air must be cleaned of all kinds of oils, impurities and moisture. If the pneumatic angle grinder weighs less than the electric model, then this advantage is offset by the weight of the hose. However, every experienced craftsman will take this as a small compensation for the high quality of work.

Angle Grinder Safety

Working with an angle grinder requires great attention, care and the necessary safety precautions. The angle grinder must be equipped with a special protective cover, with which the operator is protected from dust, sparks and the ingress of any small particles. The angle grinder cover is the main protective element.

To ensure smooth operation of the tools, take care of protective equipment. glasses and gloves.

Availability of a soft start system

The angle grinder is a fairly powerful power tool, therefore, when it is switched on, the mains can be subjected to extremely heavy loads. The smooth start system of the angle grinder helps to avoid such peak loads. over, the smooth start-up of the grinder significantly reduces the physical wear of parts and the likelihood of damage to the processed material. With such a start, the likelihood of injury is also reduced, since the mechanical jerk when turned on is eliminated.

In the line of the angle grinder Dnipro-M there are two models with a soft start system. MShK-2300P and MShK-2700. These are rugged power tools built for the toughest jobs.

Size and Weight Selection Angle Grinder Angle Grinder

The greater the weight and size of the angle grinder, the more difficult the tasks it will have to perform. And vice versa. If you need a tool for everyday tasks of average difficulty, it is better to choose an angle grinder with 115 mm. Cutting with such a small circle will definitely not be convenient and these types are often used for grinding.

angle grinder 125 mm. the most popular tool among the people. Such devices are small, not heavy, convenient, have decent power characteristics and, importantly, inexpensive. Such an angle grinder is convenient for both grinding and cutting. Disc size 180 mm. this is already a lot for cutting, and such an angle grinder is suitable for construction work. This size can be used to cut both thick pipes and bricks.

angle grinder 230 mm. this is the maximum that can be found by the diameter of the circle. Bricks, tiles, boards, pipes can be cut with such a tool without much effort, but it is better not to use it for grinding.

Attachments, discs and discs for an angle grinder

When working with an angle grinder, you should also pay attention to the diameter of the cutting disc (or grinding wheel), since the thickness of the material depends on it, for which you can use a particular tool.

Angle grinder cutting discs have diameters from 115 to 230 mm. Here you can notice the following feature: the more power the angle grinder is, the larger discs it can work with. That is, the maximum wheel diameter is directly proportional to the power of the grinder. Note that the most popular are angle grinders, the disc diameter of which is 125 mm. Such a hand grinder. the most suitable option for most household needs.
