• Cuts up to 2x as fast as conventional abrasives

• 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.

With a die size of D/F 5HL and 500FH, these discs fit a variety of applications. The dimensions and grade make them versatile for use on metals, composites, and gelcoat surfaces.

Durable Film Backing

The discs feature a film backing instead of paper, which offers greater tear resistance and edge retention. This backing enhances durability, allowing the discs to last longer even under tough sanding conditions. It also helps maintain consistent performance throughout the abrasive life.

Film backing is especially useful when working on rough or uneven surfaces, reducing the chance of disc damage. This makes the 3M Cubitron II 775L a reliable choice for extended projects.

Efficient Hookit Attachment

The Hookit system provides a hook and loop attachment for easy disc changes without adhesive residue. This format allows quick removal and reattachment, making sanding more efficient and less messy. It’s designed for repeated use throughout the disc’s life.

Hookit discs are preferred in environments where adhesive-backed discs might get contaminated by dust or dirt. This system also tends to leave finer finishes, making it suitable for applications requiring precision.
