3M 7100145427 Abrasive Film Disc 240 Grit 5 Inch Hook Loop

Product Description

The 3M 7100145427 is a coated abrasive film disc in the Cubitron II 775L series, designed for high-efficiency stock removal on a wide range of substrates. It measures 5 inches in diameter and carries a 240 grit rating. The disc uses 3M Precision Shaped Grain technology, a triangular ceramic mineral engineered to slice through material rather than gouge or plow like conventional abrasive grains. The result is a disc that cuts significantly faster and lasts considerably longer than standard abrasives. The film backing provides superior tear resistance and edge retention compared to paper-backed alternatives. This disc is intended for use by trade professionals and finishing technicians in demanding material removal applications.

The 775L disc is suited for stock removal work on metals, composites, and other hard substrates in both production and shop environments. The hook and loop attachment system allows fast disc changes without tools, making it practical for high-volume or multi-grit finishing workflows. The 5-inch diameter and 240 grit combination positions this disc for intermediate to fine stock removal passes where surface consistency and disc longevity both matter.

Installation Notes

Installation is performed by pressing the disc firmly onto a compatible 5-inch hook and loop backing pad until fully seated. Ensure the sander is powered off and unplugged before changing discs. Inspect the backing pad for wear or contamination before attaching a new disc, as a damaged pad will reduce grip and disc performance. Follow all applicable shop safety guidelines and wear appropriate PPE including eye and respiratory protection during sanding operations.
