Mounted on a 3/32" mandrel, three 3M radial bristle discs deliver fast, superior results! The unique, three-dimensional abrasive/flexible bristle design provides a uniform finish. Use them for heavy cleaning, for removing firescale and light oxide, and for pre-polishing, semi-finishing, blending, texturing and polishing. Discs provide the convenience of a pre-charged abrasive but don't generate the heat associated with rubber wheels.
Remove oxides from jewelry without using messy compounds. Clean and maintain hard-to-reach areas and fine detail. Embedded Cubitron mineral abrasive is much harder than most metals.Recommended handpiece speed is 15,000rpm.
