Our 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, 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. We offer 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 reused again and again for the extent of the abrasive life.
