Radial Bristle Discs 80 Grit
3M Radial Bristle Discs will give you the best possible finish and polish with a rotary tool. Use 80 grit to remove firescale from sterling silver. These larger discs can be stacked 4-6 discs on mandrels for use with flex shaft and micromotor handpieces, and on spindle adapters for the polishing/bench lathe. Bristle discs last a long time and can be used right down to the nub.
