3M™ Cubitron™ II Hookit™ Clean Sanding Abrasive Disc 737U 75mm Multihole is a premium-performance sanding disc designed for professional automotive refinishing, delivering exceptional cutting speed, durability, and dust extraction. Developed using 3M's revolutionary Precision-Shaped Grain technology, these discs provide faster sanding, longer life, and a more consistent finish than conventional ceramic abrasives.

Available from Independent Paint Supplies, the 75mm Cubitron II 737U Disc is ideal for SMART repairs, spot repairs, paint preparation, feather edging, filler shaping, primer sanding, and blending work. The compact 75mm size makes it particularly effective for working on smaller repair areas, contours, and hard-to-reach sections where precision and control are essential.

The advanced ceramic grain technology features precision-engineered triangular abrasive particles that continuously fracture during use, exposing fresh cutting edges and maintaining exceptional cutting performance throughout the life of the disc. This allows the disc to cut at least 30% faster and last at least 30% longer than traditional ceramic abrasives, helping to improve productivity and reduce abrasive consumption.
