These aluminum-oxide miniature brush burs are used to buff and remove scratches or other damage on your jewelry projects, or spot-refining stone finishes.
Use these small aluminum oxide rotary brushes in your Foredom flex-shaft handpieces or Dremel compatible with a 2.35mm shank. Please note that the 12mm brushes have a smaller than usual shank measuring 2.3 mm thick, 15 mm length, so it will need to be securely inserted in your handpiece before use.
Rotary brush burs are also available with silicon carbide, diamond abrasive, crimped brass or steel wire, or less abrasive cloth and synthetic materials.
