Practically to any used buildingelectric tools can be selected special nozzles, which have specific characteristics and purpose. Let's look at how to choose a disc for metal for Bulgarians, with what kinds of them it will be able to work.
They may be aimed at not workingonly with metal, but also with stone, tile, concrete and brick. Conditionally they can be divided into polishing, abrasive and diamond circles cut-off for the Bulgarian. The former are simply metallic or additionally with a cloth coating. Abrasives are made from crumbs, gradually during operation, these discs are cut off for the grinder. Diamond possesses small elements of industrial diamond, which positively affects the term of their work and production characteristics.
Somewhat different from abrasive diamond wheels. Here it is worth paying special attention to their labeling. The letters indicate what was used in the manufacture. Next to them are the numerals. They indicate the size of the grain. If the numbers are large - then the disc was created to cut black metal. Small - it's aimed at color. If the figures are generally miniature, then this indicates that the circle was created for cutting steel.
The choice of a circle depends on the scope of work and financialopportunities. The products of the CIS countries, the European Union and China are widely represented on the market. Luzhsky Abrasive Plant deserves special attention and its products. The most successful and at the same time pleasant in quality are such products:
On the products of other countries it is worth noting thatslightly from the quality of us behind the producers of the European Union. The least successful assortment is offered to us by China. When selecting a disc, make sure that it has information on compliance with GOST, and also indicated the symbols of the scope of application. Be bypassed by those circles where the European Union is indicated as the producer, and not the specific country. The presence of such a mark indicates that before you Chinese (read - low-quality) fake. But to avoid unpleasant moments, it is recommended to focus on domestic samples. They are very cheap (which makes their forgery unattractive), besides they are of high quality. But how much is the circle cut-off? The price for abrasive models starts from 20 rubles / piece (if you talk about "Hitachi" and "Luga") and can safely exceed the mark of 50 rubles (and if you buy more expensive models or dealers, do not be surprised at a few hundred dollars). Diamond is more hardy to use, so their average price is estimated at 3-4 thousand rubles, and to the best one you need to add one more zero.
