3M Radial Bristle Discs 400 Grit

3M Radial Bristle Discs 400 Grit

Use this grit after 220 grit or equivalent. Remove all traces of 220 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 400 grit to smooth and blend. These work best when stacked at least 4 to a mandrel (6 is ideal). Order 1 screw mandrel for each grit. Stack at least 3 discs per mandrel (6 is maximum) so the bristles sweep in a clockwise direction. Bristle discs last a long time and can be used right down to the nub. See our selection of miniature mandrels to fit your flexible shaft or rotary tool. Mandrels sold separately. Use with 1/8" or 3/32" screw mandrel.
