3M 7100145451 Abrasive Film Disc 6 in 400 Grit Hook Loop

Product Description

The 3M 7100145451 is a Cubitron II Hookit 775L abrasive film disc engineered for high-speed stock removal on metal, composites, and coated surfaces. It uses 3M Precision Shaped Grain, a triangular ceramic mineral that slices through substrate material rather than plowing or gouging the way conventional abrasives do. The result is a disc rated to cut up to 2x faster and last up to 6x longer than standard abrasive discs. At 6 inches in diameter with a 400-grit rating and a maximum speed of 12000 RPM, this disc is built for precision finishing and aggressive material removal in professional shop and field environments.

This disc is suited for metalworking, fabrication, and finishing operations where consistent cut rate and disc longevity matter. The film backing increases tear resistance and maintains edge integrity under sustained use. The hook-and-loop attachment system allows fast disc changes without tools, making it practical for high-volume work. Typical applications include weld blending, surface prep, and contour finishing on ferrous and non-ferrous metals, as well as composite panels and painted surfaces.

Key Features

• 3M Precision Shaped Ceramic Grain slices substrate for faster cut and longer disc life
• Cuts up to 2x faster than conventional abrasive discs
• Lasts up to 6x longer than conventional abrasives under comparable conditions
• Film backing provides greater tear resistance and edge retention
• Hook-and-loop attachment enables tool-free disc changes
• Suitable for a wide range of stock removal applications across multiple substrate types

Compatibility

Designed for use with 6-inch hook-and-loop random orbital and disc sanders operating at or below 12000 RPM.

Installation Notes

This disc is installed by a professional or experienced operator onto a compatible hook-and-loop backing pad. Confirm the sander backing pad is clean and free of debris before attaching the disc to ensure full contact and secure hold. Do not exceed the rated maximum speed of 12000 RPM. Inspect the disc before each use and replace if torn, loaded, or worn unevenly.
