3M 7100044445 Cubitron Ii Hookit 732U Disc 6 Inch 80 Grit

Product Description

The 3M 7100044445 is a Cubitron II Hookit Clean Sanding Paper Disc in the 732U series, designed for high-efficiency stock removal on metal, paint, primer, and body filler. It features 3M Precision Shaped Ceramic Grain, a triangular mineral that slices through material rather than plowing across the surface like conventional abrasives. This design produces a disc rated to cut up to 2x faster and last up to 4x longer than standard aluminum oxide or ceramic discs. At 6 inches in diameter with an 80 grit rating, this disc suits aggressive material removal passes in fabrication, bodywork, and surface prep applications. It is used by metal fabricators, auto body technicians, and general shop personnel.

The 732U disc is built for stock removal on a wide range of substrates including bare metal, coated steel, aluminum, and painted surfaces. The hook-and-loop (Hookit) attachment system allows fast disc swaps without tools, reducing downtime on production or repair work. A precise multi-hole pattern across the disc face connects to dust extraction ports on compatible random orbital and disc sanders, keeping the work surface clear and improving visibility during use. This disc is suited to both production shop environments and single-unit repair scenarios.

Key Features

• 3M Precision Shaped Ceramic Grain slices substrate for faster, cooler cutting
• Cuts up to 2x faster than conventional abrasive discs
• Lasts up to 4x longer than conventional abrasive discs
• Hook-and-loop (Hookit) attachment for tool-free disc changes
• Multi-hole pattern designed for superior dust extraction compatibility
• 80 grit rating targets aggressive stock removal and surface leveling

Compatibility

Designed for use with hook-and-loop random orbital and disc sanders that accept 6-inch abrasive discs with multi-hole dust extraction patterns.

Installation Notes

Mount the disc onto a compatible hook-and-loop backing pad before use, ensuring the disc seats flat with no lifted edges. Always verify the sander RPM rating does not exceed the disc maximum RPM before operation. Connect the sander to a dust extraction system or vacuum when using the multi-hole pattern to maintain visibility and reduce airborne particulate. Wear appropriate eye protection and a respirator rated for fine particulate when sanding coated or painted surfaces.
