Diamond blades for Bulgarians: review, description, specifications and reviews

To be able to perform various repair and construction works, the master must apply the appropriate types of tools. For angular grinding machine (USM), or, as it is called in common speech, Bulgarians, use different nozzles. This allows you to perform many operations. Such equipment is used both for large volumes of work and for home repair.

The largest share of the work performed by the Bulgarian, is cutting. To obtain an excellent result, it is necessary to use diamond wheels of high quality. To choose a suitable variety, you need to use expert advice, user feedback.

General characteristics of the instrument

The Bulgarian, like many other power tools, has removable elements. This allows us to carry out a wider range of works. A diamond disc for a Bulgarian needs sharpening or just a timely replacement. Therefore, from time to time, it is simply necessary to purchase new replaceable attachments.

It should be noted that there are simple and diamond discs for the angle grinder. The last option is stopped more often, since it is a more durable piece of equipment. However, depending on the amount of work, you need to choose the characteristics of the disks.

The greater the load it will be subjected to, the hardier and more expensive the tool. It is also important to initially take into account the conditions under which diamond disks will be used. For each type of material, the appropriate variety is used.

Types of discs by type of edge

Each cutting element of the grinder consists of a cutting edge (diamond) and a steel body. Depending on the type of working surface, there are 3 types of removable elements of the UWB.

Solid cutting discs allow you to do work without losing material. This is important for ceramic tiles, marble. The cut thus becomes equal.

The segmented diamond cutting disc has cutouts for cooling. Therefore, it is used for cutting concrete, brick.

This nozzle produces cooling by a dry or wet method. In the first case, air enters the work surface through the disc chutes. The second option involves cooling with water or special substances.

Combined diamond cutting blades allow dry processing of the material or with the use of water cooling.

Disk Usage

Depending on the type of material, which is processed with the help of the USM, a diamond disc is distinguished for metal, concrete, ceramic tile, wood or even glass. These removable elements can be universal or highly specialized. Therefore, when selecting, the manufacturer's recommendations should be taken into account.

For dense, hard materials, the cutting edge is made of milder steel varieties. This allows the surface to release a new layer of diamond when abrasion occurs.

By the way of application, there are three types of tools. It is a diamond disk for sharpening, cutting and grinding. For each operation, you must choose your own version.

Grinding will allow polishing the surface to be treated. Cutting is most often used to separate ceramic tiles or other materials into parts of the required size. Sharpening is performed only when the grip is fixed. In this case, it is possible to process drills, chain saws, etc. To work as safely as possible, it is necessary to follow the manufacturer's recommendations clearly.

The principle of operation of the disk

The performance characteristics that a diamond segmental disk or solid disc possesses depend on the technology of making the cutting edge. It differs by the principle of application of the substance, its granularity, and also by the binding element.

A layer of technical diamonds should not only be superficial. The entire cutting edge must have this material in its structure. In this case, the service life is significantly increased. This is especially important for the processing of foam concrete, brick.

With a similar treatment, a diamond cutting disc not only cuts as much as the surface sticks. In this case, the working layer is also erased. During processing, the internal structure of the material is exposed. Therefore, it is important that diamond spraying is spread throughout the thickness of the disk.

The technology of applying the diamond segment

Depending on processing conditions, diamond spraying can be applied by different methods. When choosing a disk, this must be taken into account. Otherwise, the incorrectly selected removable element will not work for long.

If diamond spraying is applied to the surface using silver solder, this version of the tool is used exclusively when there is water cooling. Without it, such a diamond disc for Bulgar is quickly destroyed.

If the surface is sprayed with laser welding, the product is considered durable. It is used for dry processing. This is a very durable version of the application of technical diamond chips.

When using a geometric closure, the coating is applied by thermal treatment with a binder. This version of the disc is used for all types of cutting.

What to look for when buying?

First of all, when choosing a tool, it is necessary to pay attention to the dimensions. The internal diameter for the bulgarian is 22 mm. If the diamond disk is cut using stationary equipment, it may be necessary to use a tool with a diameter of 25.4 mm.

External size of the disk is 115, 125, 230, 350 mm. Depending on the type of work you need to choose one or another option.

Having determined the dimensions, it is necessary to establish the accuracy of the processing. For a very accurate cut, a continuous spraying should be preferred. Segment varieties are suitable for concrete. It should also be noted that when processing the material by a dry method, it is necessary to stop the tool every 1.5-2 minutes. Therefore, the process is a little delayed.

Disks for home use

In the conditions of carrying out home repair by your own hands, you do not need to purchase expensive professional equipment. The volume of such work, as a rule, is small. Therefore, dials for Bulgarians, used by domestic craftsmen, may be less hardy.

Their resource is enough to cut a small amount of ceramic tiles or stonecutting a concrete wall. The cost of such a tool will be acceptable to any user.

The diamond disc, the price and quality of which is optimally suited for domestic use, is produced by domestic companies Zubr, Centroinstrument, Spartak. The cost of such products with a diameter of 230 mm is approximately 500 rubles per unit. Products of small sizes (up to 125 mm) will cost the user 200 rubles. As users say, this is quite an acceptable cost.

Professional Equipment

A professional tool is exposed to long and heavy loads. Therefore, higher demands are put to it in terms of strength. Stationary equipment or portable professional models can use a diamond disk for sharpening, cutting or grinding for a long time.

At the same time, the possibility of continuous operation is a priority. With a large amount of work, this saves time and improves the processing performance.

Professional diamond varieties of tools are distinguished by their narrow specialization. Their cost is much higher than the simple domestic removable elements of the USM, but the longevity is impressive.

The most famous manufacturers of such disks are the companies Bosch, Distar. The starting price of their products is 2500 rubles. When carrying out work by professional builders, the cost of such diamond disks quickly pays off.

Exploitation

To ensure that diamond discs are long and productive, it is necessary to correctly process the material. Having selected a suitable variety, it is necessary to observe the rules of labor safety. The Bulgarian, judging by the reviews, is an unsafe tool.

Always wear a respirator and safety goggles. Sharpening is performed exclusively on stationary, fixed types of equipment.

Prior to sawing, it is necessary to mark the place of future processing. Then a guide cut is made. The material is processed to the required depth.

As noted by experienced users, it should be remembered that for dry inserts it is necessary to stop the saw blade every 1.5 minutes, and when wet it is time to bring water to the disk.

After considering the presented diamond wheels, you can purchase the best option. Existing varieties must be selected in accordance with the profile of activities. If you plan to do work at home, it is not necessary to buy an expensive tool. But in the hands of professionals, quality durable discs will pay off very quickly. With proper maintenance, they will last long and productive (reviews confirm this). It is only necessary to follow the rules of work on such an electric tool.
