3M 7010365885 Finishing Flap Brush 8x1x3 in Medium Aluminum Oxide

Product Description

The 3M 7010365885 is a finishing flap brush designed for light-duty cleaning and finishing applications across a range of surfaces. The brush measures 8 inches in diameter, 1 inch in face width, and mounts on a 3-inch arbor bore. Individual abrasive sheets are adhered at a 90-degree angle to the core, allowing each sheet to flex and conform to irregular or contoured surfaces. The abrasive mineral is medium-grade aluminum oxide with a medium hardness density rating of 5A. This tool is commonly used by metal fabricators, maintenance technicians, and finishing tradespeople who need consistent surface prep without aggressive material removal.

This flap brush suits light cleaning, deburring, and surface conditioning tasks on metal, wood, and composite materials. The 90-degree sheet orientation provides consistent contact across the work surface, making it well suited for finishing passes on flat stock, tubing, and fabricated components. It is sold individually and weighs 0.56 pounds, making it easy to handle in bench-mounted or handheld tool configurations.

Key Features

• Individual abrasive sheets adhered at 90 degrees to the core for flexible, conforming contact
