3M Radial Bristle Disks

The 3M small Radial Bristle Disk has a flexible bristle design that can be used for cleaning, pre-polishing, semi-finishing, blending and texturing. They are excellent for use on gold, silver, copper, pewter and brass applications. Radial Bristle Discs are especially good at removing the oxides from jewellery without having to use messy compounds. They are great for cleaning hard to reach areas and fine detail.

 

  • Colour coded to help selection of the proper grit.

  • Flexible bristles conform to the workpiece and clean without removing the base material.

  • Uniform concentration of abrasive mineral provides a higher cut rate than wire brushes.

  • Provides a faster, more uniform finish and lowers operational costs.

  • Discs can be mounted individually or stacked together.
