3M Radial Bristle Disc Master Kit

Radial bristle discs work like natural bristle brushes with the abrasive built into the bristles, so a bench can run the whole finishing sequence without adding polishing compound. The 3M Radial Bristle Disc Master Kit gathers all three disc sizes, 1", 3/4" and 9/16", together with mandrels for each, in one set. Stack the discs onto a pin hole mandrel, four to six make an effective brush, and the flexible construction runs cool to help prevent heat damage while giving a uniform, easy to control finish from aggressive stock removal through final high polish. An eighteen compartment storage box keeps the grits sorted.
