Use 3M Cubitron II Hookit Clean Sanding Abrasive Disc 737U to remove paint, shape body filler, fine feather-edging, final prep before priming, or even surface structure removal of clearcoats and preparation of blending areas. 3M developed 3M Cubitron II Hookit Clean Sanding Abrasive Discs 737U for superior cut and long disc life during these key stages in auto body repair. It features 3M Precision Shaped Grain technology. This triangular shaped grain cuts 30% faster and lasts at least 30% longer than traditional ceramic abrasives. With its wide range of grades available, the disc is ideal for many sanding applications in collision repair. Cubitron II products have raised the bar for high performing abrasives. The combination with the multi-hole pattern on our abrasive disc offers excellent dust extraction, further increasing cut rate and disc life. 3M Cubitron II Hookit � Clean Sanding Abrasive Discs 737U attach to a hook‐and‐loop backup disc pad, can be removed cleanly and easily, and can be re‐used again and again for the extent of the abrasive life. When used with a 3M � Clean Sanding Disc Pad, the disc holes do not require alignment with the pad holes, making switching the discs fast, easy, and convenient.
