3M Radial Bristle Disc 1"

Great for cleaning and maintaining hard to reach areas on platinum, gold, silver, copper, pewter and brass pieces. Embedded mineral abrasive is harder than most metals.

Removes oxides without messy compounds. These discs do not generate the same amount of heat as rubber wheels do. Can be used individually, or stacked.

Note: Bristle brushes up to 1" diameter use with mandrel hole 1⁄16" or 1⁄8".
