Our 3M Hookit attachment system provides excellent backing support and further simplifies disc changes, optimizing disc life, while the film backing provides a consistent finish. The purple aluminum oxide disc comes in a variety of sizes and is available in a range of grades.
Sandpaper discs cut better and last longer when dust isn?t 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 sanding debris collects in 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.
