Practically to any used building electric tool it is possible to pick up special nozzles which possess specific characteristics and purpose. Let's look at how to choose a metal disc for a Bulgarian, with what kinds of metal it can work.

Types of cutting wheels

They can be aimed at working not only 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 crumb, gradually during operation, these discs are cut off for the Bulgarians soak. Diamond possesses small elements of industrial diamond, which positively affects the term of their work and production characteristics.

Choose the size

When choosing a cutting wheel for metal, pay attention to its inner and outer diameter. There are nine types of baits. You can install any cutting disc for metal on a professional Bulgarian. Home usually have an external parameter of 125 millimeters, which allows to judge them as the most popular in everyday life. The inner circle is called a small circle, due to which the circle is set on the bulgarian. It is not recommended to overlook these disk parameters from your attention, as they can differ from what is on the device. Although if we talk about a cut-off circle of 125 millimeters, then the occurrence of such a precedent is very unlikely. And if we talk about using a grinding angle machine of a well-known brand with an equally popular pattern of a disc, then the emergence of such a situation - generally from the realm of fantasy.

When do we need a cutting circle for metal and which one to take?

This is the most accessible type. It is designed exclusively for working with metal products. In the mass of their make abrasive. Thanks to them it is possible to cut sheet metal, metal profile, corners, channel. If we consider the most popular in everyday life Bulgar with 125 millimeters, it should be noted a wide variety of assortment of circles that the market offers us.

Next to them are the digital symbols. 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.

Disks of different companies

The choice of a circle depends on the amount of work and financial possibilities. The products of the CIS countries, the European Union and China are widely represented on the market. Luzhsky Abrasive Plant and its products deserve special attention. The most successful and at the same time pleasant in quality are such products:

1. "Luga".
2. "Hitachi".
3. "Russland".

On the products of other countries it is worth noting that manufacturers of the European Union are lagging behind in terms of quality. The least successful assortment is offered to us by China. When choosing a disk, 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 does a 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 from resellers, 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 it is necessary to add one more zero.

Click on it and, without letting go, start to unscrew the nut using the key. Then remove the used disc and replace it with another one. Press the nut and tighten it with the key.
