3M 7100029967 Psa Cloth Disc 5 Inch P120 Grit Ao

Product Description

The 3M 7100029967 is a PSA cloth sanding disc engineered for heavy-duty material removal in industrial and trade finishing applications. The disc uses an aluminum oxide abrasive bonded with a resin system that resists heat buildup, extending disc life during aggressive stock removal. A pressure-sensitive adhesive backing mounts directly to a backup pad or steel platen for fast, secure attachment and clean removal when swapping discs. At 5 inches in diameter with a P120 grit rating, this disc is suited for intermediate sanding stages where surface prep and scratch pattern consistency matter. Rated at 12000 RPM for use with compatible rotary tools.

This disc is designed for both wet and dry sanding environments, making it adaptable across metal fabrication, woodworking, composites, and general surface preparation. The X-weight cloth backing resists tearing and edge wear under load, which is critical in production or high-cycle shop environments. Trades including metal finishers, fabricators, and industrial maintenance technicians will find this disc appropriate for bench grinders, disc sanders, and rotary finishing tools equipped with a PSA-compatible platen or backup pad.

Installation Notes

Power down and disconnect the tool from its power source before mounting or removing the disc. Ensure the backup pad or platen surface is clean and free of debris before applying the PSA backing to promote full adhesion. Do not exceed the rated 12000 RPM maximum speed. Licensed trade professionals should follow applicable shop safety standards and tool manufacturer guidelines during disc changes and operation.
