3M 7100145430 Hook and Loop Film Disc 240 Grit 3 Inch

Product Description

The 3M 7100145430 is a coated abrasive hook-and-loop film disc designed for aggressive stock removal on a wide range of substrates. It uses 3M Precision Shaped Ceramic Grain, a triangular mineral engineered to slice through material rather than gouge or plow like conventional abrasive grains. The result is a disc rated to cut up to 2x faster and last up to 6x longer than standard abrasive discs. At 3 inches in diameter and 240 grit, it suits fine to medium stock removal tasks where consistent cut rate and disc longevity matter. The film backing resists tearing and holds its edge through demanding use cycles.

This disc is suited for metal fabrication, woodworking, and composite finishing applications where controlled stock removal is the priority. The 240 grit makes it appropriate for blending, surface prep, and finish work following coarser stock removal passes. The hook-and-loop attachment system allows fast disc swaps without tools, reducing downtime during high-volume production or service work. It is sold individually and fits standard 3-inch hook-and-loop backup pads used across pneumatic and electric random orbital sanders.

Key Features

• 3M Precision Shaped Ceramic Grain cuts up to 2x faster than conventional abrasives
• Grain geometry slices substrate rather than gouging, extending disc life up to 6x
• Film backing provides greater tear resistance and edge retention versus paper backing
• Hook-and-loop attachment enables tool-free disc changes
• 240 grit suited for stock removal, blending, and surface preparation
• Compatible with a wide variety of substrates including metals, wood, and composites

Compatibility

Designed for use with standard 3-inch hook-and-loop backup pads on pneumatic and electric random orbital sanders.

Installation Notes

Ensure the backup pad surface is clean and free of debris before attaching the disc to maintain full hook-and-loop contact. Operate the sander at the speed recommended for the tool and application. Inspect the disc before each use and replace if the film backing shows tears or if the grain appears glazed or loaded. Always wear appropriate eye protection and a respirator rated for the dust generated by the substrate being worked.
