3M 7000121871 Non-woven Abrasive Disc 4.5 Inch Medium

Product Description

The 3M 7000121871 is a non-woven abrasive disc designed for light-duty blending, cleaning, deburring, and surface finishing on a variety of metals. Built on a flexible, open nylon web construction with aluminum oxide (AO) mineral at a medium grade, this disc delivers moderate aggression without loading up with debris. The pliable web conforms to irregular surfaces, making it practical for both flat stock and contoured workpieces. Fabricators, maintenance technicians, and metalworkers reach for this disc when a job calls for controlled material removal with a consistent surface finish.

This disc is suited for light industrial applications where surface prep and finish quality matter. Typical tasks include cleaning mill scale, removing light oxidation, deburring machined edges, and blending weld seams on ferrous and non-ferrous metals. The medium grade strikes a balance between cut rate and finish refinement, making it a go-to choice for general shop use across metal fabrication and maintenance environments.
