About Hookit™
3M offers a complete range of hook-and-loop style Hookit™ velcro discs for work spaces where adhesive backed discs may become contaminated by dust, dirt, or flying debris. Hookit™ sanding velcro discs conveniently and firmly attach to a hook and loop backup disc pad (sold separately) on a random orbital sander, can be removed cleanly and easily, and can be reused again and again for the extent of the abrasive life.
About 3M™ Clean Sanding
The multi-hole pattern on 3M™ Clean Sanding discs evacuates dust better than 6-hole products—significantly increasing cut-rate and disc life. When used with a 3M™ Clean Sanding Disc Pad, the disc holes do not require alignment with the pad holes, making switching the discs fast, easy, and convenient. You can also pair Clean Sanding abrasives with Clean Sanding velcro discs pads for use on a central-vacuum-ready sander.
