Nozzles and discs for concrete for grinders
There is special equipment that allows you to facilitate the repair or construction, especially for those who produce all these processes on their own, without the involvement of specialized workers. In this article we will talk with you about one of these tools - manual grinder, tell you about the amenities and all the possibilities.

The appointment of an angle grinder
Anyone who has ever encountered construction or repair work knows how convenient it is in all respects to own a universal tool, rather than a set of specialized ones.
This greatly simplifies and simplifies the relocation from object to object, reduces the cost of additional costs by:
- Purchase of spare parts, additional equipment and accessories.
- Service and repair tools.
Perhaps the most popular and sought after, both among professional builders and a simple man in the street, who does everything with his own hands, something there is always building and rebuilding in his own possessions, we can safely call the Bulgarian. So it is called in simplicity, among specialists this tool is called an angle grinder. (See also the article How to drill a concrete wall with a drill: features.)

Instructions for this tool recommends using it in several ways:
- Cutting materials of any strength.
- Grinding of various surfaces.
- Shuffle.
- Polishing.
- Sharpening
A wide range of use of the grinder due to the many nozzles of different nature used on the basis of this tool. It is about them that will be discussed in this article.
Attachments for the grinder
Most often, the grinder is used for cutting materials into parts, shaving in monolithic and prefabricated structures of any type for laying engineering networks, cutting expansion joints in the road surface. For these purposes, use of cutting discs, the most common and known to almost everyone - interchangeable cutting attachments on the grinder.

Cutting discs
Cutting discs различают по сфере использования:
- Concrete.
- By metal.
- By tree.
- Stone.
- On glass.

Note! The price of diamond discs is higher compared to others and varies from a few dozen to thousands of rubles, depending on the materials from which it is made and the size. You can purchase accessories for any grinder, in the same place where angle grinders and other similar tools are sold.
For each individual material should be purchased specifically designed for him cutting diamond discs. They come with a solid edge and discontinuous with slots of a certain character. Cutting discs also vary depending on the fraction of diamond deposition.
For example, a disk on the grinder on the concrete should have a diamond coating of the fine fraction and a transverse groove over the entire diameter. The diamond disc, on the contrary, for processing stone has a continuous edge.

Of course, it is more appropriate to use a diamond disc for cutting concrete with a grinder for materials of similar strength:
- Porcelain stoneware.
- Stone (artificial and natural).
- Reinforced concrete.
- Tile (here plays a role not so much the strength of the material being processed, as high demands on the accuracy and accuracy of the cut).
In addition to the scope of use, all cutting discs are classified by size (diameter and thickness).
The outer diameter of the disk dictate the dimensions of your equipment:
- Small.
- Average.
- Large tool.
Depending on this, the following types of cutting tips are produced.
- Disc on concrete for Bulgarian 125 mm.
- 150 mm.
- 180 mm.
- 230 mm.
The thickness of the cutting disc can be from 1 mm to 3.2 mm. Small diameter discs are available in any thickness, large discs are only thick.
Cutting discs по дереву оснащены зубьями разного калибра. Наиболее точной порезки можно добиться с мелкозубчатым диском.
Attention! Cutting nozzles for wood are considered the most dangerous in work. Therefore, working with them, as, incidentally, cutting of reinforced concrete with diamond circles should be carried out with the utmost responsibility to observe the safety instructions for conducting such work. In no case should not remove the protective cover from the grinder.

Grinding wheels for concrete
From the name, the purpose of grinding and as an analogue for thinner work of polishing discs is quite understandable.
Depending on the requirements for the nature and degree of processing, a nozzle is installed on the grinder with:
- Sandpaper the desired number.
- Felt.
- Sponge
- Cloth.
For rough grinding use finely abrasive grinding wheels. Grinding discs for grinders are used with the same success for rough removal of irregularities on a concrete or stone surface, and for the final polishing of a car body in a car repair shop.
Grinding discs are classified according to the degree of grit in the following order:
- Disks with a grain size from 40 to 80 are used for the initial coarse processing.
- Disks with a grain size from 100 to 120 level the surface.
- Final grinding is performed with discs with a grit index of 180 to 240.
Tip! When purchasing tips on the grinder, carefully read the accompanying papers or consult a consultant, since the visually detachable discs look almost monotonous, and an unknowing person may make a wrong choice.
Sharpening and grinding nozzles
The functionality of the grinder significantly expands through the use of an additional class of nozzles:
- Abrasive grinding wheels.
- Diamond roughing.
- Twisted cones.
Using these nozzles, you can sharpen tools, clean welds, remove old paint, dried concrete or cement mortar. Diamond drilling of holes in concrete, which is possible only with the use of a specialized tool, also deserves particular attention. Of course, you can drill and make holes in the plates and ordinary drills, but the hole may not turn out even and neat.

Conclusion
Now you understand that the so-called Bulgarian is not a terrible, but a very useful tool that can be used to carry out many different processes. Be careful, you must choose the nozzles strictly according to the recommendations for the work that you are going to produce.
