3M 7100045948 Psa Cloth Disc 5 Inch P180 Grit Ao

Product Description

The 3M 7100045948 is a PSA cloth sanding disc designed for heavy-duty material removal in professional grinding and finishing applications. The disc uses an aluminum oxide abrasive grain bonded with a resin system that resists heat buildup, extending disc life under sustained use. A pressure-sensitive adhesive backing mounts directly to a compatible backup pad or steel platen, holding firm during operation and releasing cleanly for fast changeovers. At a 5-inch diameter with a P180 grit rating and a maximum operating speed of 12000 RPM, this disc handles both wet and dry sanding tasks across a range of surface materials.

This disc is suited for metal fabrication shops, woodworking operations, and maintenance environments where consistent stock removal and surface conditioning are required. The X-weight cloth backing resists tearing and edge wear during aggressive passes, making it appropriate for production-level use. Technicians and fabricators working on flat or contoured surfaces will find the PSA mount system reduces downtime during disc changes. The disc performs on ferrous and non-ferrous metals, wood, and composite surfaces.

Key Features

• Pressure-sensitive adhesive backing adheres securely to backup pads or steel platens and removes cleanly for fast replacement

Compatibility

Designed for use with backup pads or steel platens that accept 5-inch PSA-mount sanding discs. Verify that the tool and pad are rated for at least 12000 RPM before mounting.

Installation Notes

Ensure the backup pad or platen surface is clean and free of debris before applying the disc. Do not exceed the rated maximum speed of 12000 RPM. Power down and disconnect the tool from its power source before mounting or removing any disc. Inspect the disc for damage before each use and replace immediately if cuts, tears, or delamination are present.
