3M 7010300782 Finishing Flap Brush 8x2x3 in Very Fine

Product Description

The 3M 7010300782 is a finishing flap brush designed for light-duty cleaning and finishing applications across a range of surfaces. Individual abrasive sheets are adhered at a 90-degree angle to a central core, creating a flexible, conformable brush structure that conforms to contours and irregular profiles. The abrasive mineral is very fine grade aluminum oxide, making this tool appropriate for surface prep, light deburring, and final finishing passes. The soft, conformable density allows the brush to work into tight areas without aggressive material removal. At 0.97 pounds, it is lightweight enough for extended handheld or mounted use by machinists, fabricators, and maintenance technicians.

This flap brush is suited for cleaning, blending, and finishing operations on metal, wood, and composite surfaces. Its 8-inch diameter, 2-inch face width, and 3-inch arbor hole size make it compatible with bench grinders, pedestal grinders, and similar rotary equipment. It is commonly used in fabrication shops, maintenance facilities, and production environments where controlled surface finishing is required without heavy stock removal.
