3M 7100145472 Cubitron Ii 775L Film Disc 180 Grit 5 Inch

Product Description

The 3M 7100145472 is a coated abrasive film disc from the Cubitron II 775L series, designed for high-speed stock removal on a wide range of substrates. It uses 3M Precision Shaped Grain technology, where triangular ceramic mineral particles are engineered to slice cleanly through material rather than plowing or gouging like conventional abrasives. At 5 inches in diameter with a 180 grit rating, this disc delivers a controlled finish cut while maintaining an aggressive material removal rate. It features a hook and loop attachment system for fast disc changes and a film backing that resists tearing and holds its edge under sustained use. Installed by metalworkers, fabricators, and finishing technicians in production and repair environments.

This disc is suited for stock removal applications on metal, composites, and other hard substrates in both production shop and field repair settings. The 180 grit rating positions it as a finishing-stage disc following coarser material removal passes. The hook and loop backing makes it compatible with standard 5-inch random orbital and right-angle sanders equipped with hook and loop pads. It performs well on flat and contoured surfaces where consistent finish quality and disc longevity are priorities.

Key Features

• 3M Precision Shaped Grain ceramic mineral slices through substrate for faster, cleaner cuts
• Cuts up to 2 times faster than conventional abrasive discs
• Lasts up to 6 times longer than conventional abrasives, reducing disc change frequency
• Film backing provides greater tear resistance and edge retention compared to paper-backed discs
• Hook and loop attachment enables quick disc changes without tools
• 180 grit rating suited for finishing and light stock removal passes

Compatibility

Designed for use with 5-inch hook and loop random orbital and right-angle sanders; compatible with standard hook and loop sanding pads accepting 5-inch diameter discs.

Installation Notes

Ensure the sander pad surface is clean and free of debris before attaching the disc to achieve full hook and loop engagement. Power down and disconnect the sander from its power source before changing discs. Inspect the disc for damage before each use and do not use a disc that shows tears, delamination, or missing grain. Follow applicable workplace safety standards and use appropriate respiratory and eye protection when grinding or sanding.
