Attachments for the grinder: a variety of tools for the ear

The grinder, which is also called an angle grinder (USM), is a universal device. With this tool, you can perform various types of processing, such as cutting, grinding, polishing, strobing, etc. USM is suitable for working with stone, metal, as well as wooden blanks. The effectiveness of the device depends on the correct selection of the nozzle on the grinder. In order not to make a mistake when choosing the right product, you need to study its types.

Processing of almost any material is carried out with the help of angle grinding equipment with a variety of nozzles

What are the nozzles for the grinder: main characteristics

On the modern market, you can find many varieties of circles for earwax. A huge number of modifications can confuse an inexperienced person. Each type of nozzle has its own operational features that determine the design of the product. Differentiation of such instruments occurs according to the following criteria:

purpose;

The purpose of the nozzle on the grinder is determined by its marking

material of manufacture;
size.

Today you can find a lot of circles on the grinder, which are used for processing metal, wood or stone parts. The purpose of the product is determined by its marking. It is worth noting that some types of nozzles are universal. For example, a stone circle is often used for cutting ceramic tiles, concrete and brick products.

However, most disks are suitable only for highly specialized work. Metal nozzles should never be used when cutting wooden logs or boards. And the circles that are used for roughing steel are not commonly used for stainless steel.

Useful information! Why is a Bulgarian called a Bulgarian? The answer to this question is very simple: in the USSR, the first samples of this device appeared in the 70s. They were delivered from Bulgaria, so this name was fixed for the device.

The nozzles on the grinder are divided according to the class of processing, the degree of rigidity and roughness

Angle grinders are used for cutting and grinding materials. If desired, you can choose a circle for processing glass, plastic or marble slabs. All tools for USM are divided into types according to the class of processing, as well as according to the degree of rigidity.

Classification of attachments on the ear, depending on the type of work

Nozzles that are used for cutting various materials can be used to perform many operations. Each device has unique properties and design. Depending on the purpose of the nozzle there are:

cut – off;
saw blades;
stripping;
stripping (grinding);
to perform stitches;
polishing.

Cut-offs. Such circles are used when it is necessary to cut or cut the material (rough). The cutting nozzle for the ear has the shape of a disc equipped with a cutting edge. In some cases, such circles are equipped with a solid cutting part, and sometimes with a segmented one.

The cutting part of the saw head for the grinder has sharp teeth

Saw blades. According to the name, it is clear that such products are used for cutting various wood parts. The peculiarity of these nozzles is that their cutting part has teeth. Such discs are widely used for cutting wood, drywall, chipboard and fiberboard. With the help of a saw wheel, you can perform an even cut of ordinary and laminated boards. It is worth noting that the teeth of the saw blades for the grinder may differ in shape, which affects their operational purpose.

Stripping. Such nozzles are used for grinding metal, concrete and wooden blanks. Using such a disk, you can easily remove an old layer of paint or varnish from the surface. Grinding wheels are also used to eliminate the primer. If necessary, grinding is carried out with the help of these products.

Stripping. Stripping nozzles are classified as a stripping group. They are circles whose edges contain metal wire. Stripping discs are used to remove rust from metal surfaces, as well as to eliminate other types of persistent contaminants. Most often they are used to prepare pipes for painting.

Cutting wheels are used when it is necessary to cut or cut the material

One of the most common types of cleaning nozzles is a petal circle. This product is used for processing workpieces made of metal, wood and plastic. The petal circle is a disk, along the edges of which small pieces of sandpaper are fixed. Depending on the nature of the work, the granularity of the working components is selected. On the modern market, you can find varieties of petal disc:

end faces;
batch;
having a mandrel.

A stripping (grinding) nozzle for a grinder with a mandrel is used when it is necessary to ensure high accuracy of work. Many products belonging to this group are used to eliminate burrs after cutting metal and plastic pipes.

Useful information! With the help of stripping wheels, the finishing treatment of welds is carried out.

Polishing nozzles for the grinder are: felt, felt, and sandpaper

Suture nozzles are used to organize stitches in stone products, concrete, as well as asphalt pavement. Suture circles have a special design that allows you to perform such work.

Polishing. These products are used for polishing surfaces. Most often they are used after grinding. The following types of discs can be attributed to this group: felt, felt, as well as an emery wheel. Velcro is used to fix them on the tool, so they are very easy to change.

Nozzles for the grinder: classification by material

Various materials are used for the manufacture of nozzles that are used while working with USM. All of them are highly efficient, and are also manufactured taking into account safety regulations. For example, many metal circles have special slots filled with copper to prevent overheating of the disk during operation. Let’s consider from what materials it is possible to purchase circles for the ear.

Diamond discs are used for processing metal, stone products, concrete, ceramics and glass

Diamond circle. Such products include two components. The first of them is a steel base, and the second is diamond spraying. Such discs are used for processing metal workpieces, as well as products made of stone, concrete, ceramics and glass. The diamond wheel for the grinder is characterized by high efficiency and accuracy of work. With the help of it, the thinnest cut of the workpiece is performed.

“Turtle”. Such a nozzle also has a diamond coating, but the base in this case is represented by flexible rubber, which is characterized by high strength. The disc got this name due to the corrugated structure. Diamond-coated circles are fixed to the base by means of Velcro.

A carbide disk. For the manufacture of such devices, metals are used, the alloy of which forms a strong connection. The edges of such circles contain solder, which includes high-carbon molybdenum steels. Chromium and nickel impurities are also included in the solder, which increases the resistance of the product to adverse operational factors. Such discs are used for cutting metal (less often wood).

The “turtle” nozzle has a grooved structure, and diamond-coated circles are fixed to the base with Velcro

Abrasive. Such a circle is made of latex paper, the main characteristics of which are density and resistance to moisture. Similar devices for earwax include a special reinforcing mesh in their structure. An abrasive layer is applied to such a base. Circles of this type used for grinding may have a polymer base.

Cleaning. This disc includes a metal wire, with the help of which paint, varnish and heavy dirt are removed from the treated surface. The diameter of such a wire is selected depending on the nature of the work.

Pay attention! Separately, it should be said that the nozzles used for earwax include support plates. Such products are made of polymer materials or durable rubber. They are used in combination with some grinding and polishing tools.

Cutting devices for the grinder: their features

Cutting a wide variety of materials is the most popular operation for which USM is used. A very important point necessary to perform this task is the competent selection of the nozzle. The choice is made depending on which material will be processed. For example, cutting wheels are used for metal cutting, for the production of which a crystalline mineral – corundum is used.

Competent selection of the nozzle is carried out thanks to its markings

All circles for the grinder are marked with color depending on their purpose. For example, it is customary to use discs with blue markings for cutting metal objects. It is important to remember that cutting wheels are recommended to be installed on speed-controlled grinders.

Cutting products for metal processing are also differentiated by size. The basic geometric data of such nozzles include:

outer diameter;
thickness.

Metal cutting discs are available for three types of USM: small, medium and large. The diameter of these products varies from 115 to 230 mm. 125 mm circles are very popular. Products with a diameter of 150 and 80 mm are less common.

The thickness of such devices ranges from 1 to 3.2 mm. Accordingly, large circles are made of greater thickness in order to have sufficient rigidity. And for small nozzles, this indicator can be completely different.

Metal cutting discs are available for three types of USM: small, medium and large

The cutting nozzles that are used to work with stone and concrete are made of a completely different material – silicon carbide. Such an abrasive ensures the effectiveness of USM when cutting white bricks, as well as slate. The most common type of grinder is considered to be the USM 125 (with speed control). This is due to the fact that it is the most functional and has a low weight.

Silicon carbide is not suitable for processing red bricks. In this case, it is customary to use circles with diamond coating applied to a metal base.

Wood disc for grinder: choosing the right tool

Varieties of wood discs for USM: sawing, cutting, stripping, grinding and polishing. Rules for the use of USM for wood.

Such products have a green marking, which allows you to accurately select them for the grinder. Photos of silicon carbide products, as well as other types of disks, make it possible to visually assess their differences.

Pay attention! Different discs are used for cutting wood. This can be a chain circle, along the edges of which a chainsaw chain is installed, or a metal product with teeth (circular).

Circles for the grinder are marked with color depending on their purpose

Experts recommend taking into account the technical characteristics of wood when choosing a nozzle for a grinder. The chain saw is most suitable for working with wooden products. This material has a high viscosity coefficient, so it is the most difficult to process. Before starting work, it is recommended to study the safety rules and take the necessary precautions.

Stripping nozzles for the grinder: varieties

To eliminate paint and varnish materials and rust, special stripping nozzles are used. This group includes several types of disks that differ in the material of manufacture and characteristics. In order to remove the paint layer from the pipe, metal scrapers are used. The Bulgarian is often used for such work. Korschettes can have the shape of a bowl or disk with coils of metal wire around the edges.

In order to select the required processing intensity, it is required to select the desired wire diameter. In this case, there is a certain pattern. For a rougher impact, nozzles with a wire of a larger diameter are used. Accordingly, a thinner wire is used for gentle processing.

To choose the required intensity of processing the material with a nozzle, you need to choose the desired wire diameter

The design of the nozzles takes into account two wire placement options. In the first case, it is collected in bundles of various thicknesses, and in the second – it is located freely. The nozzles for the grinder for removing paint from metal products are very popular. It is worth noting that, in addition to corsets, there are other devices that belong to the group of stripping, such as:

diamond stripping nozzles;
abrasive grinding wheels.

They have a lot in common with each other. However, the location of the abrasive material in this case is different: it is located along the perimeter of the disc. Thus, the processing is performed somewhat differently. It is important to remember that diamond-coated stripping nozzles are not commonly used for metal workpieces. They are used to remove layers of stone, concrete and other materials similar in characteristics.

In turn, abrasive grinding nozzles, which also belong to the category of stripping, are used in working with metal products. With the help of such tools, you can perform rough processing of the workpiece. There are many options for using such products. Their design is great for grinding metal. Attachments for this type of grinder are used for processing welds, as well as for sharpening knives. The thickness of these products may be different, but it should not be less than 5 mm.

Abrasive grinding nozzles are used in working with metal products

Useful information! The versatility of the USM has influenced its widespread use. The Bulgarian is used in almost all areas of construction. This tool is used for cutting, grinding, polishing and other processing options for a variety of materials.

Grinding nozzles for the grinder: rough and gentle processing

Grinding is one of the most popular processes for which USM is used. With the help of such a tool and a set of attachments, rough and gentle processing of metal, stone and wooden surfaces can be carried out. As a rule, grinding precedes polishing of workpieces. The nozzles that are used in this case may consist of sandpaper or felt material.

A petal disc for a grinder has become widespread. This tool consists of a circle (base), along the edges of which the petals of sandpaper are fixed. They may have different grain sizes. This indicator is selected depending on the nature of the work.

The use of a petal circle allows rough processing of blanks from different materials. With the help of it, you can also perform finishing grinding. Fine-grained petals are used for finishing.

The petal disc for the grinder consists of a base, along the edges of which sheets of sandpaper are fixed

Today you can find another kind of grinding discs for a grinder. Some abrasive products are fixed to the base by means of a special Velcro. To use such a circle, it is necessary to screw it onto the tool spindle.

Polishing is the softest wood treatment. For polishing works that relate to the finishing stage of grinding a particular material, special felt discs are used. And also on the market of tools you can find circles, the working part of which consists of dense fabric. The nozzles on the grinder for polishing are very popular when working with wood, since their use allows you to bring the surface of the material to the smoothest possible condition.

Nozzles on the grinder for rough processing of various materials

For rough grinding of various surfaces, special discs are used, which have their own characteristics. Rough processing of wood is aimed at eliminating knots, as well as a layer of bark. The use of such nozzles for metal workpieces allows you to remove paint and rust.

With the help of a special nozzle on the grinder, you can perform rough processing of the workpiece

Today it is possible to distinguish several types of nozzles for grinding on a grinder. For example, stripping discs are very popular. Among them there are products that are used for processing stone and concrete (diamond) and abrasive wheels used for metal parts.

Stripping products are often used to remove an old layer of paint. In some cases, they are used to remove the varnish. Another common variant of the nozzle on the grinder is the korschetki. The design features of these elements are reflected in their effectiveness. The disc, which has a metal wire, is able to quickly remove paint from the metal surface.

Pay attention! On the market of building materials, you can find end circles for the ear. Such products are used when it is necessary to align the cutting line of the board. The alignment of the ends with oblique sawing is done quite often, so this tool can be called indispensable.

We should also mention the nozzles for polishing cars. For rough processing of paintwork (LCP) machines use special woolen discs. The material in such a circle can be arranged freely or twisted into dense threads.

Felt and felt discs are very popular for polishing cars

Also, abrasive discs are used for rough processing of cars, which are characterized by high functionality and a longer service life.

Today you can find other attachments on the grinder for polishing cars. For example, felt and felt discs are very popular. Vulcanite nozzles are used for finishing the car’s paintwork, the main material of which is rubber.

Nozzles on the grinder for grinding: gentle treatment

For non-rough grinding of certain materials, petal nozzles are used first of all. They, as already mentioned above, consist of petals located close to each other and having an abrasive coating (sandpaper).

The grain size of the petal nozzles can be different. It is selected depending on the nature of the work. It is worth noting that the design of this grinding nozzle allows it to serve for quite a long time, which is an undoubted plus. In shape, the individual petals resemble a trapezoid.

The nozzles on the grinder for grinding are made of sandpaper, felt or dense fabrics

The second type of nozzles, which belong to the group of soft ones, are grinding wheels. They are made of sandpaper, felt or dense fabrics. Discs of this type are fixed by means of Velcro on a plate base. As a rule, they are sold in a set.

A set is used for processing wood, which includes 5 disks. They all duplicate each other. In case of wear of one circle, it will not be difficult to replace it with a new nozzle. Similar products are used for finishing wooden surfaces. There are other nozzles on the ear, which are used for grinding wood. For example, wood cutters for a grinder are very popular.

Felt circles, as well as products that include dense fabric in their design, are used for wood processing. It is important to remember that to carry out grinding with the help of such circles, it is necessary to use a special wax paste. It is applied to the surface of the part before starting work.

Another type of nozzles, which is used for finishing wooden surfaces, is cup products. They consist of nylon villi, which together form a fairly dense coating.

Cup products are used for finishing wooden surfaces

Which discs for grinding concrete and metal are used most often

For grinding concrete, two types of nozzles are used on the ear: diamond and abrasive. It is important to remember that its effectiveness depends on the diameter of the circle. The larger the disk, the more load it is able to carry.

Pay attention! Discs of this type are actively used in the installation of concrete screed. Its grinding makes it possible to significantly improve the strength characteristics. At home, a grinder equipped with a special nozzle is quite enough to perform such an operation.

The nozzles for the grinder for grinding concrete can be purchased on the market, in a hardware store or place an order online. To date , there are two methods of grinding this material:

dry;
wet.

The tape file for the grinder is ideal for grinding in hard-to-reach places

In the first case, the operation is performed using special disks. Dry grinding of concrete is highly efficient, but it also has some disadvantages. The main disadvantage is abundant dust formation. Before starting dry sanding, it is necessary to prime the surface, which will increase its strength.

Wet (or wet) grinding of concrete differs from the previous method in that it involves the use of water, and this avoids the formation of dust. This type of grinding is considered to be of higher quality, however, when using a grinder, it is impossible.

It is important to remember that grinding and polishing with a grinder are two completely different processes. When polishing, the surface of the material is processed to make it smooth. In turn, grinding is necessary to level the surface.

Grinding of metal products is carried out using special discs. They include the following materials: silicon carbide, electrocorundum, etc. And also in the composition of such circles there are special fiberglass nets.

Dry grinding of concrete is highly efficient, but has a serious disadvantage – abundant dust formation

For grinding metal, various brushes are used, which consist of a wire located on a metal base. In addition, today you can buy other, more technological attachments for the grinder. The tape file is a direct confirmation of this. It is used for polishing, grinding and rust removal. It is worth noting that the grinder should have a smooth speed adjustment, which is a prerequisite for the use of such a nozzle.

Grinding discs for metal are used for the following operations: tool sharpening, finishing of welds, as well as cleaning the surface from rust and paint. When choosing metal nozzles, it is necessary first of all to be guided by the amount of work you have to perform.

Nozzles on the grinder for grinding wood: features

Petal and round nozzles are used for grinding wood surfaces. In the first case, the sandpaper is fixed around the perimeter of the disk. In turn, round discs provide for the attachment of sandpaper circles with Velcro. Both options of nozzles for wood processing are quite convenient. In some cases, such tools are equipped with a special adapter that allows you to use the disk on the drill.

On the petal nozzles, sandpaper is fixed around the perimeter of the disk

Useful information! The nozzles for the grinder for grinding wood may have different grain sizes. Her choice depends on the type of work. Coarse–grained products are used for rough, rough processing, and fine-grained products are used for finishing.

Which tool is more suitable for grinding wood? This operation can be performed with the help of a USM or a special grinder. The choice of tool depends on the purpose for which the surface will be treated. If grinding is necessary in order to prepare the wood for painting, then you can use a special disc on the ear.

For varnishing wood, it is best to treat it with a grinder. There are several varieties of this equipment. Devices of the longitudinal type are so called because of the direction of movement of the emery tape. In turn, in the vibrating variety, circles are used on which an abrasive material is applied.

Coarse–grained nozzles are used for roughing, and fine-grained ones are used for finishing

Metal Grinder Brushes for Rust cleaning and Wood Processing

Many people believe that only steel products can be cleaned with the help of brush attachments that are used for earwax. However, such tools are also used when it is necessary to process wooden parts. Brass wire nozzles are used for wood.

Brushes have some advantages over abrasive discs. They have a long service life and a lower cost. They are used when it is necessary to remove rust or old paint from the workpiece. Separately, it should be said that brushes are indispensable tools when processing hard-to-reach places.

Brass nozzles on the ear for wood processing allow you to remove the paint and varnish material as efficiently as possible. Brushes are used not only for cleaning surfaces. This tool is also used when it is necessary to artificially age the wood. This process is called brushing.

Brushing is used to create unique interior design items. Using the USM, it is possible to process small objects. On an industrial scale, such a tool is not used. The brush attachment on the grinder allows you to highlight such elements of wood as rings and various irregularities.

Metal brushes for the grinder are used when it is necessary to remove rust or old paint from the workpiece

Metal brushes are able to quickly and effectively remove old paint from steel pipes, eliminate rust and plaque. When choosing such nozzles, it is necessary to pay attention to their rigidity, since the operational efficiency of brushes depends on this indicator.

Stroborez nozzle on the grinder: recommendations for choosing

To use such a nozzle, it is necessary to have a USM, which provides for the possibility of installing a second saw blade. And it is also necessary that it has an outlet for connecting a vacuum cleaner. When stroblenie forms a fairly large amount of construction debris. To protect the master during work, a casing for the ear is used.

Pay attention! The nozzles for crushing are not suitable for all Bulgarians. The device must be powerful enough to provide the desired result. The minimum USM value in this case should be at least 1500 watts.

Before buying discs, you should pay attention to the length of the shaft. This element must necessarily have a sufficient length necessary to install an additional circle. The second disc is needed to form the opposite wall of the groove.

To use the stroborez nozzle, it is necessary to have a grinder, which provides for the possibility of installing a second saw blade

The dimensions of the disk itself also play an important role. This is due to the fact that the diameter of the circle affects the cutting depth and work efficiency. Safety is also an important point, depending on the dimensions of the nozzle on the grinder for crushing.

Such a design affects the nature of the load: it becomes more uneven. Therefore, when choosing a tool, it is necessary to pay attention to which type the bearings belong to. Conventional ball parts fail much faster. Experts recommend to use for crushing of USM with roller bearings. Needle products are also suitable for such work.

During the work, the crushing circles should act in one direction – towards the master. Otherwise, the tool will push off from the work surface.

Before starting work, it is necessary to attach a nozzle for a vacuum cleaner grinder to the ear. A tube is fixed to it, which is required to remove dust and larger particles. During operation, it is necessary to hold the tool firmly in order to exclude the possibility of discs jumping off.

Experts recommend using a grinder with roller bearings for crushing

Bulgarian nozzle for a chainsaw: recommendations for choosing a tool

If necessary, the grinder attachment can be installed on a chainsaw. It is not difficult to purchase such a product in any store that specializes in the sale of gasoline tools. Its installation is described in detail in the instructions, so there should be no problems.

Some chainsaws are simple in design, so it is much easier to install a grinder on them. For example, the chainsaw Calm is very popular. The grinder nozzle on the saw may be suitable for some models, compatibility with which is not specified in the technical documentation of the tool. In order to choose the nozzle correctly, experts recommend comparing the diameter of the crankshaft of the saw with the same indicator of the hole of the grinder.

The variety of attachments on the modern market makes it easy to change the purpose and operational characteristics of the device. However, not everyone knows about the possibility of converting a chainsaw into a cutting and grinding tool. Most people are familiar with the reverse option – a saw attachment on a grinder.

It is easier to install a grinder on chainsaws that are simple in design

Pay attention! When buying such a saw head, one important point must be taken into account. The selection of a grinder is carried out for a specific model of a chainsaw.

The nozzle pulley, which is the leading one, can be of different types. Before buying, it is necessary to evaluate the compatibility of the main star of the chainsaw and the pulley of the nozzle. If the tool does not fit in size, then it is impossible to install it instead of the clutch.

Varieties of pulleys attachments of Bulgarians for a chainsaw

It should be noted right away that there is no official classification of pulleys of this type of attachments. Let’s consider the most common variants of pulleys. The first of them belongs to the chainsaw Calm 180. It has some design features. Such a pulley looks like a closed bowl. Such an element is not collapsible and is used in the following modifications of the saw Calm: MS 180, MS 250 and MS 170.

The grinder attachment to the chainsaw Calm 180 can be installed on the drive sprocket of the saw without removing the clutch. In this case, there is a lack of a bowl at the pulley. There are several variants of this design, which are classified depending on the step of the asterisk. The main advantage of this type of nozzles is that they are very easy to mount. And it is also worth noting their reasonable cost.

The grinder attachment to the chainsaw Calm can be installed on the leading sprocket of the saw without removing the clutch

Professional-type chainsaws differ in that they have a clutch, the sprocket of which can be replaced if necessary. Special pulleys are used for such devices. The cost of this tool is more, however, its quality characteristics will be better.

The grinder attachment for chainsaws Calm, Partner, Taiga, etc. is used when it is necessary to perform an even cut on wood or metal. During operation, you need to be careful, and before starting it, you must check the correctness of the installation of this nozzle.

Rating of Bulgarians of 2018: the best models in terms of cost and quality

To date, there is a huge variety of Bulgarians, which differ in the manufacturer’s company, technical characteristics and cost. Some models are very popular, as consumers note their advantages over standard devices. Before purchasing this tool, it is recommended to pay attention to the USM rating, which contains the best representatives who have certain advantages.

Bulgarian Bosch GWS 20-230 H of a well-known German manufacturer, is distinguished by high quality of assembly and its components

Interschool USM-125/1100E. This model of the Interskul brand belongs to the budget segment. Its distinctive feature is the largest capacity among inexpensive Bulgarians. Many users note another advantage of this device – a soft start.

The cost of this tool is only 3900 rubles. Of the minuses, only a large mass of the product can be noted. It is used for disks with a diameter of 125 mm. For circles of 230 mm, there is a heavier model from the company Interskul – USM 230.

Makita GA5030. Such a Bulgarian costs about 4000 rubles, so it is also referred to the budget segment. The main advantage of this device is the minimum number of vibrations during its operation, which affects the convenience of operation.

The Makita GA5030 angle grinder has a fairly small power (only 720 watts). However, this is quite enough to work with metal pipes, ceramic tiles and wood. The weight of the device makes it easier to work with it. The weight of this model is 1.4 kg.

The Bulgarian Makita GA5030 costs about 4000 rubles, so it belongs to the budget option

Bosch GWS 20-230 H. A Bulgarian of a well-known German manufacturer, which is distinguished by high quality of assembly and components. The cost of the model is approximately 7,200 rubles. Such a device belongs to the middle price segment.

Useful information! Many users note that the Bosch earpiece of this series is one of the best options for home use. It is also worth noting that an additional handle and 8 different circles are included with the device itself.

Hitachi G18SS. An effective device that has a very affordable price (6000 rubles). The advantage of this model is that it has a large reserve of endurance and has protection against overheating. The Hitachi Bulgarian is a great option for use at home.

Safety precautions when working with discs for the grinder

The use of any construction tool has its own nuances. Before using the grinder, it is necessary to study safety precautions in detail, since improper operation of it can lead to serious injury.

Before you start working with a grinder, initially it is necessary to assemble and equip it correctly

The safety of the USM operation is primarily ensured by the protective casing. In case of a split disk, this element protects the master from fragments. In no case is it recommended to remove the casing from the grinder.

The direction of rotation of the disk is also an important point. It is impossible to allow situations in which the movement of the circle will be reversed from the master. This can lead to the fact that the Bulgarian will break out of your hands. The direction of movement of the disk should always be in the direction of the person working with the ear.

For use at home, it is recommended to purchase a speed-controlled USM. This is due to the fact that different materials require different speeds of rotation of the circle. One of the most important rules: it is strictly forbidden to operate disks that do not correspond to a particular material.

And, finally, the last thing to remember is that you can not use USM for other purposes. The passport of the device clearly indicates what a particular grinder can be used for, as well as the limits of its functionality. If all the above rules are observed, working with the grinder will be as safe as possible, and the tool itself will last for more than one year.

For use at home, it is recommended to purchase a speed-controlled USM

USM is a very common tool that can be purchased on the market, in a store or ordered online. This device has many use cases precisely due to the possibility of changing the nozzles. Before purchasing a grinder, it is necessary to take into account what it will be used for and study the range of discs. Choosing the right nozzle will allow you to do the job quickly and efficiently, and most importantly – safely.
