The 3M Hookit attachment system makes disc changes fast and easy, meaning that you can use the disc again and again for the extent of the abrasive life. The strong, C-weight paper backing on our 3M Hookit Clean Sanding Disc 236U supports aggressive sanding and minimizes edge wear.
3M Hookit Clean Sanding Disc 236U is excellent for blending and finishing on aluminum and carbon steel, as well as woodworking applications for heavy and medium stock removal and finishing on hardwoods, softwoods, and composites. Our clean sanding discs also work well on primer, paint, sealers, topcoats, fiberglass, and plastics.
Sandpaper discs cut better and last longer when dust isnt loading the cutting surface of the abrasives. Reducing dust is easier than ever with 3M clean sanding discs. An open coat means the abrasive grains have space between them so that dust escapes through the spaces rather than loading 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.
Our proprietary multi-hole pattern evacuates dust from the disc at a high rate. This hole design doesnt even require alignment of holes with the disc pad (which is attached to a random orbital sander and sold separately), making disc changes quick and simple. The 3M Hookit attachment system uses a hook and loop design that makes disc changes fast and easy. All of this adds up to improved productivity and reduced material consumption.
