The grinder is far from being such a simple and safe tool as it might seem at first glance. If you approach its use carelessly and even more so do not follow safety precautions, then you can easily lose not only your fingers. Before taking on a grinder, it would be nice to know at least about the most common mistakes, which ultimately lead to extremely sad consequences.

2. Cable damage
Working with absolutely any power tool that has a damaged power cord is guaranteed not to end well. The grinder in this respect is never an exception. In the worst case, a damaged wire can cause a fire or simply shock the careless master.
3. Incorrect disc direction
When working with a grinder, it is very important to ensure that the disc is in the correct direction.

4. Lack of protective gear

A special mask will not be superfluous. In addition, the grinder itself must have a protective cover for the disc. Without the latter, it is impossible to start work in principle, since almost half of the most severe injuries as a result of accidents are associated precisely with the scattering of fragments.
