3M 7010309531 Brite Cut Polish Flap Brush 6x4x2 in 5A Med

Product Description

The 3M 7010309531 is a Brite Cut and Polish Flap Brush engineered for heavy-duty surface finishing applications where a higher-polished result is required. The brush measures 6 inches x 4 inches x 2 inches and is built around a rigid core with individual abrasive sheets adhered at a 90-degree angle. The abrasive mineral is aluminum oxide at a medium grade, and the brush is rated 5A medium density and hardness. This combination delivers consistent cut and polish performance on metal, composite, or similar workpiece surfaces. It is sold as a single unit and weighs 2.26 pounds.

This flap brush is intended for applications where surface preparation demands both material removal and a refined finish in the same operation. Typical use cases include deburring, blending, and polishing on fabricated metal parts, weldments, and machined components. The medium hardness and aluminum oxide construction make it well suited to ferrous and non-ferrous metals in industrial, manufacturing, and maintenance environments. Machinists, fabricators, and maintenance technicians are the primary users.
