3M Radial Bristle Disc - 3" Diameter
A new design in polishing and cleaning. These 1/16" thick abrasive impregnated discs feature flexible bristles that can be used for cleaning, pre-polishing, blending, and texturing. They can be used on precious and semi-precious metals. The discs are flexible and thin enough to get into crevices and small places. To cover larger areas, stack several discs on a wheel adapter. You should stack 3 to 8 bristle discs together for best results.
Blue discs are 400grit and can be used for light cleaning or pre-polishing.
