3MTM CubitronTM II HookitTM Clean Sanding Film Disc 775L

  • Revolutionary 3M Precision Shaped Grain technology provides fast cut and long life
  • Cuts up to 2x as fast as conventional abrasives
  • Film backing for greater tear resistance and edge retention
  • Ideal for a wide variety of substrates and applications focused primarily on stock removal
  • Hook and loop attachment makes disc changes fast and easy
  • Precise multi-hole pattern provides superior dust extraction

3M™ Cubitron™ II Hookit™ Clean Sanding Film Disc 775L features 3M Precision Shaped Ceramic Grain a revolutionary advancement in abrasive technology. The triangular shaped ceramic mineral is designed to slice through the substrate rather than gouging or “plowing” like conventional abrasives resulting in a disc that cuts up to 2x as fast and lasts up to 6x as long as conventional abrasives.

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).
