3M 7100044153 Cubitron Ii Hookit Disc 80 Grit 6 Inch

Product Description

The 3M 7100044153 is a coated abrasive hook-and-loop disc engineered for high-speed stock removal on metal, wood, and composite substrates. It uses 3M Precision Shaped Ceramic Grain, a triangular ceramic mineral that slices into the workpiece rather than plowing or gouging the way conventional abrasive grains do. Rated at 10,000 RPM and sized at 6 inches in diameter with an 80 grit designation, this disc is built for aggressive material removal in grinding and finishing applications. It is used by metalworkers, fabricators, and maintenance technicians who need consistent cut rate over the life of the disc.

The 7100044153 is suited for flat and contoured surface grinding on ferrous and non-ferrous metals as well as wood composites. The hook-and-loop backing allows fast disc changes on compatible random orbital and disc sanders without tools. Primary use cases include weld blending, surface preparation before coating, and general stock removal where cut speed and disc longevity are priorities. The 80 grit rating places it in the medium-coarse range, appropriate for initial material removal before progressing to finer grits.

Key Features

• 3M Precision Shaped Ceramic Grain slices substrate for faster, cleaner material removal
• 80 grit medium-coarse designation suited for stock removal and surface prep
• 6 inch diameter with hook-and-loop backing for tool-free disc changes
• Rated to 10,000 RPM for use on standard random orbital and disc sanders
• Ceramic grain construction extends disc life compared to conventional abrasive minerals

Compatibility

Designed for use with 6 inch hook-and-loop compatible random orbital sanders and disc sanders rated at or above 10,000 RPM.

Installation Notes

Disc mounting and removal should be performed with the tool powered off and unplugged or battery removed. Verify the sander backing pad is clean and free of debris before attaching the disc to ensure full hook-and-loop engagement. Do not exceed the 10,000 RPM speed rating printed on the disc. Inspect the disc for tears, gouges, or delamination before each use and discard any damaged discs immediately.
