Description
These 7/8" silicone wheels contain pumice abrasive that will not mar or scratch most stones when polishing. Use for prong and bezel finishing in already set precious or synthetic stones. This wheel is fine grit with 1/16" hole, a knife edge, and the recommended RPM is 7,000-10,000. Pumice wheels can be used with our miniature screw mandrels (BRS-274.00 and BRS-275.00).
