These 9/16” discs are the smallest size in our 3M™ Radial Bristle Discs line. They are color-coded and have flexible bristles with abrasive particles embedded throughout—no polishing compound needed! Choose from aluminum oxide or pumice (pink) in grits ranging from 80 to 1 micron.
Jewelers will like that the bristles conform nicely to curves and textures and can be used for cleaning firescale, removing scratches, and polishing tasks. Use a single disc to get into tight spaces or stack multiple discs for broader surface coverage (we like three at a time). They are excellent on precious and base metals including gold, silver, copper, pewter and brass.
- Umounted 3/4" discs with 1/16" arbor hole
- Embedded with aluminum oxide abrasive. Pink discs contain pumice instead.
