Radial Bristle Discs 400 Grit

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 screw mandrels to fit your flexible shaft or rotary tool. Mandrels sold separately
