Die Grinder

A die grinder, also known as a rotary tool, is a simple hand held power tool used for grinding, sanding, honing, polishing, or machining material (typically metal, but also plastic or wood).

The tool works by rotating a grinding nose at speeds measured in RPM or rotations per minute. The grinding mechanism makes use of an abrasive or a burr to smooth out or polish rough edges.

The air monitor and bearings uses compressed air to power the tools as the moisture in compressed air will rust the air motor, hence the motor should be lubricated daily but do not lubricate tools with flammable or volatile liquids such as kerosene, diesel or fuel.

The most universal safety precaution in die grinder use is to protect one's eyes by wearing safety glasses. Other common personal protective equipment to be used  in die grinder includes  safety gloves, face shield, ear plugs / head phones and simple paper masks.

When not in use tools should be cleaned fully assembled and then stored in a dry location to reduce rust.
