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

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 re-used again and again for the extent of the abrasive life.

Durable Film Backing

The disc uses a film backing instead of paper, which offers greater tear resistance and edge retention. This backing enhances durability during demanding sanding jobs, reducing disc failure and downtime.
