Designed for use with a random orbital sander, the strong C-weight paper backing on our 3M Hookit Paper Disc 236U resists tearing and edgewear during aggressive sanding, and the disc is resin-bonded for heat-resistance, further increasing life and cut. These discs also feature an open coat and a load-resistant coating to enhance dust management and cut-rate.
A load-resistant coating allows the disc to continue cutting even when sanding softwoods, paints, and other materials that would, otherwise, clog the surface of the disc and hinder sanding ability. Loading is further reduced by an open coat, which means the abrasive grains are spaced slightly apart so that dust can escape rather than obstructing the cutting edge of the grains, thereby optimizing cut-rate and disc life.
Sanding discs come in a variety of forms to fit various power tools and disc pads. We designed the 3M Hookit Paper Disc 236U to conveniently and firmly attach to a hook-and-loop backup disc pad (sold separately) on a random orbital sander, to be removed cleanly and easily, and be simple to reuse. A load-resistant coating prevents wood dust, paint particles, and other debris from prematurely clogging the surface of the disc, optimizing cut-rate and disc life.
