3M 7100064174 Cubitron Ii Hookit 775L Disc 5 Inch 150 Grit

Product Description

The 3M 7100064174 is a coated abrasive film disc designed for high-speed stock removal on a wide range of substrates. Built on the Cubitron II 775L platform, this disc uses 3M Precision Shaped Grain, a triangular ceramic mineral engineered to slice through material rather than plow or gouge like conventional abrasive grains. The result is a disc that cuts up to 2x faster and lasts up to 6x longer than standard abrasives. At 5 inches in diameter with a 150-grit cut, it balances aggressive material removal with a controlled finish. The polyester film backing provides tear resistance and edge retention through extended use.

This disc is suited for metal fabrication, surface prep, and finishing tasks where consistent stock removal is the priority. The 150-grit specification makes it appropriate for intermediate grinding and blending on ferrous and non-ferrous metals, painted surfaces, and composites. Hook-and-loop attachment allows fast disc changes on compatible 5-inch random orbital or disc sanders, reducing downtime in production and field environments. Fabricators, metalworkers, and finishing technicians are the primary users of this product.

Compatibility

Designed for use with 5-inch hook-and-loop random orbital sanders and disc grinders equipped with a compatible Hookit-style backup pad.

Installation Notes

Ensure the backup pad is clean and free of debris before attaching the disc to maintain secure hook-and-loop engagement. Inspect the disc for tears or edge damage before each use and replace if compromised. Do not exceed the maximum RPM rating of your tool or backup pad. Disc changes should be made with the tool powered off and fully stopped.
