3M 7100064273 Cubitron Ii Hookit 775L Disc 6 Inch 150 Grit

Product Description

The 3M 7100064273 is the Cubitron II Hookit 775L Film Disc, a coated abrasive disc engineered for aggressive stock removal on metal, composites, and painted surfaces. It uses 3M Precision Shaped Grain technology, which features a triangular ceramic mineral that slices through material rather than grinding or plowing like conventional abrasives. The result is a disc that cuts up to 2 times faster and lasts up to 6 times longer than standard abrasive discs. The film backing adds tear resistance and helps maintain a consistent cutting edge throughout the life of the disc. At 6 inches in diameter with a 150 grit rating, it suits medium-stage stock removal and surface prep work.

This disc is used in metal fabrication, bodywork, and general surface preparation applications where fast, consistent material removal is required. The hook and loop attachment system makes it compatible with random orbital and right-angle sanders equipped with Hookit backup pads. It is suited for both shop and field use by metal fabricators, auto body technicians, and trade professionals performing surface prep prior to coating or welding. The 150 grit rating positions it for intermediate stock removal and blending work across a wide range of substrate materials.

Key Features

• 3M Precision Shaped Ceramic Grain slices substrate for faster, cleaner cutting action
• Cuts up to 2 times faster than conventional abrasive discsDisc life up to 6 times longer than conventional abrasives, reducing change frequency
• Film backing provides greater tear resistance and edge retention under load
• Hook and loop attachment allows fast disc swaps without tools
• Well suited for stock removal across metal, composites, and coated surfaces

Compatibility

Designed for use with hook and loop backup pads on random orbital and right-angle sanders. Compatible with standard 6-inch Hookit-style backup pad systems.

Installation Notes

Attach the disc firmly to a compatible 6-inch hook and loop backup pad before operating the sander. Ensure the sander is powered off and disconnected before changing discs. Use appropriate eye protection and dust collection or respiratory protection when grinding or sanding. Inspect the disc for damage before each use and discard any disc showing tears, delamination, or uneven wear.
