3M 7100145453 Cubitron Ii Hookit Film Disc 5 Inch 400 Grit

Product Description

The 3M 7100145453 is a Cubitron II Hookit Film Disc 775L designed for high-speed stock removal on a wide range of substrates. It uses 3M Precision Shaped Grain technology, which features a triangular ceramic mineral engineered to slice through material rather than plow or gouge like conventional abrasive grains. At 5 inches in diameter and 400 grit, this disc is rated to 12000 RPM and backed by a film substrate that resists tearing and holds its edge longer than paper-backed alternatives. It attaches via a hook-and-loop fastening system for fast, tool-free disc changes.

This disc is suited for metal fabrication, woodworking, and composite finishing applications where aggressive stock removal is the primary goal. The 400 grit rating positions it in the fine finishing range, making it appropriate for surface prep, light deburring, and final-stage material removal before finishing. The hook-and-loop backing is compatible with standard Hookit backup pads used across grinding and sanding operations in professional trade and fabrication environments.

Installation Notes

This disc is installed by trade professionals and fabricators using standard 5 inch random orbital or right-angle grinder platforms. Before mounting, confirm the tool is powered off and disconnected from its power source. Verify the backup pad is rated at or above the 12000 RPM maximum disc speed before use. Inspect the disc for damage prior to each use and do not exceed the rated RPM.
