3M 7100045070 Sanding Disc 80 Grit 5 Inch Hook Loop

Product Description

The 3M 7100045070 is a 5-inch coated abrasive sanding disc designed for aggressive stock removal on a wide range of substrates. It uses 3M Precision Shaped Ceramic Grain, a triangular mineral that slices through material rather than gouging or plowing like conventional abrasive grains. This geometry allows the disc to cut up to 2x faster and last up to 6x longer than standard abrasives. The disc mounts via a hook-and-loop backing, enabling fast pad changes during production work. An 80-grit rating makes it well suited for initial material removal, leveling welds, and surface preparation before finer finishing passes.

This disc is used in metal fabrication, automotive bodywork, woodworking, and general surface prep applications where high stock removal rates are the priority. The film backing resists tearing and maintains edge integrity under lateral pressure. A precise multi-hole pattern across the disc face channels dust and debris away from the cut zone, keeping the abrasive surface clear and extending usable life. It is appropriate for use on metals, composites, wood, and painted surfaces in both shop and field environments.

Key Features

• 3M Precision Shaped Ceramic Grain cuts up to 2x faster than conventional abrasive minerals
• Abrasive life up to 6x longer than standard grains under comparable conditions
• Film backing provides superior tear resistance and consistent edge retention
• Hook-and-loop attachment allows rapid disc changes without tools
• Multi-hole dust extraction pattern keeps the disc surface open during use
• 80-grit configuration targets stock removal and surface leveling applications

Compatibility

Designed for use with 5-inch hook-and-loop backup pads on random orbital sanders, right-angle grinders, and similar power tools equipped with compatible hook-and-loop interfaces.

Installation Notes

Mounting and removal requires only firm hand pressure against a compatible hook-and-loop backup pad. Ensure the backup pad is clean and free of debris before attaching the disc, as contamination reduces grip and can cause disc separation during use. Power down the tool completely before changing discs. Inspect the disc for tears or delamination before each use and discard any damaged disc immediately.
