Polishing Wheels

About polishing wheels

A polishing wheel is a flat wheel of abrasive, or of soft material charged with a polishing agent, that reaches flat and broad surfaces. The FDA names the polishing wheel in its Class I list of abrasive devices and accessories. A polishing agent is defined in a glossary as any material used to impart lustre to a surface; one classical agent is pumice, a volcanic glass used as an abrasive and prepared in various grits.

A wheel rather than a point or cup, so it reaches flat and broad surfaces.
