Product Details

The 3M Radial Bristle Disc Master Kit gives professional jewelers and metalsmiths a complete range of miniature radial bristle disc wheels in all three sizes — 1", 3/4", and 9/16" — along with mandrels, in a single comprehensive set. These long-lasting discs work like natural bristle brushes but require no added polishing compound; the abrasive is built directly into the bristles. Simply stack individual discs onto the included pin hole mandrels — four to six discs make an effective brush — and you are ready to work. The flexible bristle construction runs cool, helping prevent heat damage, while delivering a uniform, easy-to-control finish across all stages from aggressive stock removal through final high polish.

Features

  • Built-in abrasive compound — no separate polishing compound needed
  • Stack multiple discs on a single mandrel to build desired brush width
  • Cool-running design helps prevent heat buildup and workpiece damage
  • Long-lasting bristles deliver a consistent, uniform finish
  • Covers the full finishing sequence from coarse stock removal to final polish
  • Includes mandrels for both 9/16" & 3/4" discs and 1" discs
