Description

The 3M 3" Radial Bristle Disc 6 Ply Brush Kit of 7 provides a complete, progressive finishing sequence in a single purchase. Each brush in the kit is assembled from 6 individual 3M radial bristle discs mounted on a 2-piece plastic tapered spindle mount configured for right-hand use on a jeweler's polishing lathe. The tapered spindle mount is designed to fit the tapered spindles traditionally found on jewelers' polishing lathes, making these brushes a direct, tool-ready solution for bench polishers and metalsmiths.

Moving through the seven grits β€” from aggressive stock removal down to ultra-fine finishing β€” allows for a systematic, controlled surface refinement process on metal workpieces.

Features

  • Complete 7-piece progressive grit kit covering coarse abrading through ultra-fine polishing
  • Each brush assembled with 6 individual 3M radial bristle discs for added body and durability
  • Mounted on a 2-piece plastic tapered spindle mount for compatibility with standard jewelers' polishing lathe tapered spindles
  • Configured for right-hand use on a polishing lathe
  • Color-coded discs for fast, error-free grit identification at the bench
  • Spans a wide finishing range: 80 grit heavy abrasion through 1 micron ultra-fine polishing

Work great on my JoolTool!

I bought these to use on my JoolTool. They are the exact same 3m radial discs and they work great! Perfect for getting into crevices to polish.
I mark the one side with a T and the other with a B to remind me which side should be facing up to ensure that my attention issues don’t cause me to ruin my discs by running them in the wrong direction.
