It is the most affordable type. It is intended solely for use with metal utensils. In the mass, make them abrasive. They can be used to cut sheet metal, sheets, angles, channel. If we consider the most popular in the home grinder with 125 millimeters, it should be noted the wide variety of circles, which offers us the market. You can find both domestic and foreign models. But despite this diversity, the cut-off wheel for metal should be used exclusively for this material. If you try this ROM to work with stone, in the best case it just wear out quickly. But it is possible that it will collapse and will cause certain harm to the person.

Slightly different from the abrasive diamond disks. Here should pay special attention to their labeling. The letters indicate that was used in the manufacture. Next to them are digital designations. They indicate the grain size. If the numbers are large – that drive was created to cut black metal. Small – he focused on the color. If the numbers are actually tiny, then this suggests that the circle was created to cut steel.

Disk Drives of various companies

The Choice of the circle depends on the amount of work and financial opportunities. On the market are widely represented products of the CIS countries, the European Union and China. Special attention is given Luga abrasive plant and its products. The most successful and at the same time it is comfortable and the are the following products:

2. Hitachi.
3. "Russland".

For products of other countries it should be noted that slightly quality behind manufacturers from the European Union. The least successful range we are offering China. When you select a drive, ensure that it had information according to GOST, as well as were specified the legend scope. Avoid those circles, where the manufacturer indicated the European Union, and is not country specific. The presence of the mark suggests that you Chinese (read - low quality) fake. But to avoid unpleasant moments, it is recommended to focus on the domestic samples. They are very cheap (which makes them unattractive forgery), to the same are of high quality. But how much is a cutoff wheel? The price of the abrasive is from 20 rubles/piece (speaking about "Hitachi" and "meadows") and can easily exceed the mark of 50 rubles (and if you buy a more expensive model or Resellers, do not be surprised of the cost of a few hundred). Diamond are more resilient with use, so their average price is estimated at 3-4 thousand rubles, and to the best, you need to add another zero.

Change drive

Periodically, the circles should be changed, as their operation. It is easy to do using a special key. Look carefully at the sander and locate the button by clicking on which is fixed the axle. Click on it and hold, start to Unscrew the nut with a wrench. You should then remove the used disc and install in its place another. Press the nut and tighten it with a key.
