3M 7000021285 Radial Bristle Brush Disc 120 Grit 6 in

Product Description

The 3M 7000021285 is a radial bristle brush replacement disc designed to clean, deburr, and finish metal and other surfaces without the hazards associated with traditional wire brushes. Each disc operates effectively with minimal applied pressure, reducing operator fatigue and surface damage risk. The 120-grit abrasive construction works across a range of coatings, oxides, and surface contaminants. At 6 inches in diameter, the disc mounts to a bench motor using the included universal benchmotor adapter. This product is sold as a refill pack and is typically installed by machinists, fabricators, maintenance technicians, and trade professionals performing surface prep or finishing work.

The 7000021285 replacement disc is suited for light deburring, surface conditioning, and cleaning applications in shop or field environments. It performs on ferrous and non-ferrous metals, composites, and coated surfaces. The disc is a practical replacement for wire brushes where wire contamination or safety concerns are a factor. The included benchmotor adapter makes fitment straightforward on standard bench-mounted rotary equipment. Minimum order quantity is 2 packs.
