3M™ Cubitron™ II Hookit™ 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. This advanced technology results 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 3M™ Cubitron™ II Hookit™ Film Disc 775L with 3M™ Elite Random Orbital Sanders.

Hookit™ Sanding Discs conveniently attach to a hook-and-loop 3M™ Stikit™ Abrasive Disc Back-up Pad (sold separately), can be removed cleanly and easily, and can be reused again and again for the extent of the abrasive's life.
