3M 25.4mm Mounted Radial Bristle Disc Assortment

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.
• Maximum is 30,000rpm.
