• 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.

3M Cubitron II Precision

The 3M Cubitron II Hookit Film Disc 775L is designed for fast, efficient cutting. This model features 3M Precision Shaped Grain technology, which slices through materials rather than gouging, allowing it to cut up to twice as fast as conventional abrasives.

Its advanced grain technology also extends the disc's life, making it a reliable choice for demanding tasks. The 775L grade ensures consistent performance across various applications.

Durable Film Backing Benefits

This disc uses a film backing instead of paper, providing greater tear resistance and better edge retention. The film backing helps maintain the disc's shape and durability during heavy use, reducing downtime for replacements.

Thanks to this backing, the disc holds up well on tough surfaces and lasts longer, making it ideal for stock removal on metals, composites, and other substrates.

Hookit Attachment System

The Hookit system allows for quick and easy disc changes. This hook and loop attachment means you can swap discs without hassle, improving workflow efficiency on the job.

Because the discs can be removed cleanly and reused, they’re a practical choice for workspaces where dust or dirt might contaminate adhesive-backed discs. The 5 inch x NH size fits standard backup pads sold separately.

Size And Format Details

This product comes in a 5 inch diameter with NH (non-hole) format, suitable for various sanding tools. The size and format make it versatile for many stock removal tasks and compatible with common orbital sanders.

The die 500X specification ensures consistent disc shape and fit, contributing to smooth operation and reliable results during use.

Large Pack Convenience

Sold as a case of 250 discs, this pack size supports extended projects without frequent reordering. The 50 discs per carton packaging helps organize supplies efficiently for busy workshops.

Having a large quantity on hand means less downtime and better cost efficiency, especially for professionals who rely on consistent abrasive performance.
