3M 7000121021 Scotch-brite 6 Inch Non-woven Finish Disc

Product Description

The 3M 7000121021 Scotch-Brite Production Clean and Finish Disc is a non-woven abrasive disc designed for fine finishing, surface conditioning, and paint preparation across a wide range of materials. Built with reinforced fiber construction and a very fine grade aluminum oxide abrasive, it delivers a high cut rate while maintaining a consistent, clean finish. The open-web, non-woven 3D structure runs cool and resists loading, extending disc life compared to standard woven alternatives. At 6 inches in diameter and rated for up to 4000 RPM, it is well suited for use on angle grinders and disc sanders in production and finishing environments.

This disc is intended for use on aluminum, stainless steel, plastics, wood, and fiberglass. It performs well in fine finishing, scratch blending, scuffing primer, and paint prep applications. The disc conforms to irregular and contoured surfaces, making it a practical choice for bodywork, fabrication, and surface restoration tasks. It is typically installed and used by metal fabricators, auto body technicians, and general tradespeople who require a consistent abrasive finish without undercutting or damaging the base material.
