Matchless Non-Woven Buffing WheelFor blending and satin finishing on flat or contoured metal parts. Very fine (~320 grit) aluminum oxide non woven material. Four ply airway buff is less aggressive than full disc wheels. Can be used to produce decorative finishes. Recommended for cleaning up welds and in areas where conventional sanders cannot reach (e. g., rim water channels) prior to polishing. Buff will need to be raked prior to initial use. Does not include a centre reducer plate.
