HEATLESS COOL WHEELS
These are hard, square-edged wheels used for deburring and finishing. The wheel's loose, coarse construction keeps the grinding process cool, so they are suitable for materials such as metal and even plastic. They will produce a heavy, matte-like finish.
Cool wheels are for use with your flexshaft machine. There is a pin hole for use with a screw top mandrel (we suggest 3/32" screw top mandrel #43.128).
The wheels can be trued with a file.
