3M 7010309552 Finishing Flap Brush 12x1x5 in

Product Description

The 3M 7010309552 is a finishing flap brush designed for light-duty cleaning and surface finishing applications. The brush features individual abrasive sheets adhered at a 90-degree angle to a central core, creating a flap-style action that conforms to irregular surfaces during use. The abrasive mineral is fine-grade aluminum oxide, and the brush is rated at a medium hardness density of 5. At 12 inches in length with a 1-inch width and 5-inch diameter, this tool is suited for bench grinder or arbor-mounted finishing work performed by fabricators, maintenance technicians, and metalworking tradespeople.

This flap brush is built for light cleaning, deburring, blending, and surface preparation on metal and similar hard materials. The fine aluminum oxide abrasive makes it appropriate for finishing passes where stock removal is minimal and surface condition is the priority. Typical applications include weld blending, part cleanup, and edge conditioning on fabricated components. The 5-inch face diameter provides good surface contact on flat or contoured workpieces.
