3M 7100189767 Scotch-brite Non-woven Disc 7-7/8 in Fine

Product Description

The 3M 7100189767 is a Scotch-Brite CF-DC Clean and Finish Disc built from non-woven material and aluminum oxide abrasive mineral. The disc measures 7-7/8 inches in diameter and is rated Fine grit. It is designed for surface blending, cleaning, and polishing tasks on metals, plastics, wood, and fiberglass. The open web construction resists loading and allows the disc to be rinsed clean for repeated use. Licensed tradespeople and fabricators working in metal finishing and surface prep applications will find this disc suited to production and maintenance work alike.

This disc is used in light to medium surface finishing applications where a consistent, clean result is required without undercutting or damaging the base material. It performs on aluminum, stainless steel, plastics, wood, and fiberglass surfaces. The conformable non-woven structure allows the disc to follow contoured surfaces and reach into corners, making it useful in both flat and complex-geometry workpieces. It attaches to a random orbital sander using a Hookit backup pad for increased cut rate and broader coverage per pass.

Installation Notes

This disc is typically installed and operated by fabricators, machinists, or finishing technicians. Before mounting, confirm the backup pad is rated for the disc diameter and the tool RPM does not exceed the disc rating. Inspect the disc for wear or damage before each use and do not use a disc that is torn or delaminating. Follow all applicable shop safety protocols including eye and respiratory protection when operating abrasive discs.
