775L 5" Sanding Discs 15 Disk Multipack Cubitron II Hookit- Grits 240+ to 400+

3M™ Cubitron™ II Hookit™ Clean Sanding Film Discs feature 3M ™ proprietary Precision Shaped Ceramic Grain, a revolutionary advancement in abrasive technology. The sharp, triangular shaped ceramic mineral is designed to slice through the substrate, rather than gouging or “plowing” like conventional abrasives, resulting in a disc that cuts up to 2x as fast and lasts up to 6x as long as conventional abrasives.

3M Hookit™ sanding discs conveniently attach to a hook-and-loop backup disc pad (sold separately), can be removed cleanly, easily, and can be re-used again and again for the extent of the abrasive life.

3M ™ proprietary multi-hole pattern on Clean Sanding products evacuates dust at a higher rate than 5 or 6-hole products. This hole design doesn’t require alignment of holes on the disc pad, making disc changes quick and simple. Open coat construction means the abrasive grains are placed with space between them to help evacuate dust and other sanding debris and avoid clogging the cutting edge of the grains. The load-resistant coating allows the disc to continue cutting even when sanding softwoods, paints, and other materials that would, otherwise, clog the disc and hinder sanding ability.
