3M 7000021280 Scotch-brite Roloc Disc 1 Inch Medium

Product Description

The 3M 7000021280 is a Scotch-Brite Roloc surface conditioning disc designed for deburring, cleaning, blending, and finishing metal and other surfaces. Built on a non-woven fiber construction, the disc conforms to irregular and contoured workpieces, helping maintain surface integrity during aggressive cutting passes. The aluminum oxide abrasive at a medium grit grade provides consistent stock removal and finishing action. The Roloc quick-change backing system allows fast disc swaps without additional hardware, making it well-suited for multi-step finishing workflows. Licensed trades and fabricators working in metal finishing, weld prep, and surface blending applications are the primary users.

This disc is intended for use on metal surfaces in light fabrication, maintenance, and finishing environments. The 1-inch diameter is suited for tight-access areas and detail work where larger discs cannot reach. The open-web non-woven construction resists loading and runs cool, supporting consistent results across extended use. It is compatible with Roloc-style quick-change right-angle die grinders and air tools equipped with a Roloc mandrel.
