Techno 15 Pcs Mini Air Die Grinder Kit With Accessories, 22000 RPM Speed (AT 7032 BK)

A hand-held power tool with a spinning spindle that holds a collet and cutting bit is called a die grinder. The purpose of a die grinder is to remove material off a workpiece or surface by rotating it at a very high speed. It is ideal for small sections that are too big for a standard one-handed angle grinder to machine. Air Die grinders run on compressed air.
