3M Cubitron II Hookit 6 Inch Clean Sanding Discs

3M Cubitron II Clean Sanding Discs have a precision-shaped grain for a super-fast cut that sands cleanly and wears evenly, so it lasts longer than conventional ceramic discs.

These high-performance abrasives reduce heat buildup, prevent discoloration, and provide superior dust extraction while shaping rough body filler, removing paint, doing fine feather-edging, or final prep work. Hookit Hook-and-loop style attachment makes disc change-outs fast and easy

Choose from six grades (grits) that range from Coarse to Medium: 40+ (25/box), and 50 discs per box for 80+, 120+, 150+, 180+, and 220+.
