3M 7010365852 Finishing Flap Brush 8x5x3 in Very Fine

Product Description

The 3M 7010365852 is a finishing flap brush designed for light-duty cleaning and surface finishing applications. Individual abrasive sheets are adhered at a 90-degree angle to a central core, creating a flexible, conformable brush action that reaches contours and irregular surfaces. The abrasive mineral is very fine grade aluminum oxide, rated at a 5A VFN designation with medium hardness and a density rating of 5. At 2.77 pounds, this brush is suited for benchtop or portable tool use by HVAC, mechanical, and general trade professionals who need controlled material removal or surface prep without aggressive stock removal.

This flap brush is used in cleaning, deburring, blending, and light finishing operations on metal, fabricated components, and mechanical assemblies. It is well suited for surface preparation work in HVAC fabrication shops, plumbing and pipefitting environments, and general mechanical maintenance settings where a consistent, fine finish is required on ferrous and non-ferrous materials. The 8-inch diameter by 5-inch face width provides broad contact coverage across flat and slightly curved work surfaces.
