These discs are ideal for a broad range of applications focused primarily on stock removal, and are effective on a wide variety of substrates, including metals, composites, gelcoat, and whitewood. The film backing offers greater tear resistance than paper discs, for additional durability and edge retention. For best results, pair with 3M™ Elite Random Orbital Sanders.
3M offers a complete line of hook-and-loop style 3M™ Hookit™ discs for work spaces where adhesive backed discs may become contaminated by dust or dirt. They are often used in applications where a 3M™ Stikit™ disc may be too aggressive, as Hookit™ discs tend to leave finer finishes than adhesive backed discs. Hookit™ sanding discs conveniently attach to a hook-and-loop backup disc pad (sold separately), can be removed cleanly and easily, and can be re-used again and again for the extent of the abrasive life.
Sandpaper discs cut better and last longer when dust isn’t loading the cutting surface of the abrasives. Our 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 with 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. All of this adds up to increased productivity and reduced material consumption. For maximum dust extraction, use this disc with a 3M™ Hookit™ Clean Sanding pad and a random orbital sander with vacuum (both sold separately).
