3M 7100044449 Cubitron Ii Hookit 732U Disc 120 Grit 6 Inch

Product Description

The 3M 7100044449 is a coated abrasive hook-and-loop sanding disc engineered for high-speed stock removal on metal, wood, and composite surfaces. Built on the 3M Cubitron II 732U platform, it uses 3M Precision Shaped Grain technology — a triangular ceramic mineral that slices through material rather than plowing through it like conventional abrasives. The result is a disc rated to cut up to 2x faster and last up to 4x longer than standard abrasive discs. At 6 inches in diameter with a 120-grit rating, this disc is suited for aggressive finishing and blending work. Licensed tradespeople and production floor technicians are the primary users.

This disc is designed for use with hook-and-loop backup pads on random orbital sanders and right-angle grinders. The 6-inch format and 120-grit designation make it appropriate for intermediate stock removal and surface prep on ferrous and non-ferrous metals, painted surfaces, and hardwoods. The multi-hole pattern built into the disc face aligns with standard dust-extraction backup pads to keep the cut surface clear and reduce airborne particulate at the work zone.

Key Features

• 3M Precision Shaped Grain ceramic mineral cuts up to 2x faster than conventional abrasive discs
• Disc life rated up to 4x longer than conventional abrasives, reducing changeover frequency
• Hook-and-loop attachment system allows fast, tool-free disc changes
• Precise multi-hole pattern supports superior dust extraction when used with compatible vacuum-ready backup pads
• 6-inch diameter, 120-grit rating suited for stock removal and intermediate surface prep

Compatibility

Designed for use with standard 6-inch hook-and-loop backup pads on random orbital sanders and angle grinders equipped for hook-and-loop disc attachment.

Installation Notes

Ensure the backup pad is clean and free of debris before attaching the disc to maintain full hook-and-loop contact across the disc face. Secure all workpieces before grinding or sanding operations and wear appropriate PPE including eye and respiratory protection. Inspect the disc for tears or damage before each use and replace immediately if damage is found. Always follow ANSI B7.1 safety guidelines for abrasive disc use.
