Use this grit after 400 grit or equivalent. Remove all traces of 400 grit polishing, then proceed to next grit for a mirror polish. 3M Radial Bristle Discs will give you the best possible finish and polish with a rotary tool. Use 6 Micron to polish. 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.
