Angle grinders


Electric angle grinders are ideal for larger areas, while the pneumatic grinders are used for small jobs and are easier to use. The application of these types of tools is for cutting and grinding operations on various materials.

With the use of appropriate accessories, one can even sharpen the knives. It is easy to overheat the metal blade grinder. Overheated metal will not stay sharp for long. To avoid overheating, apply light pressure and do not turn off the grinder. Also, it is desirable to have a bucket of water and a sponge beside to soak the metal from time to time if it gets too warm. Unlike a drill that has a speed of 700 to 1200 rpm (revolutions per minute), grinders have 10,000 to 11,000 rpm. They are quite fast, so one should be very careful.
