3M 7100117447 Finishing Flap Brush 8x2x3 in 5A Vfn

Product Description

The 3M 7100117447 is a finishing flap brush designed for light-duty cleaning and surface finishing work. Individual abrasive sheets are adhered at a 90-degree angle to a central core, creating a flap-style action that conforms to contours and delivers consistent material removal. The abrasive mineral is very fine grade aluminum oxide, rated 5A VFN, suited for final-pass finishing where scratch pattern control matters. At 8 inches long with a 2-inch face width and a 3-inch arbor hole, this brush fits standard bench or pedestal grinder configurations. Tradespeople in metal fabrication, maintenance, and HVAC sheet metal work rely on this style of brush for deburring and surface prep.

This flap brush is appropriate for light cleaning and finishing applications on metal, painted, or composite surfaces in residential and commercial maintenance settings. The medium-hardness density rating of 5 supports controlled surface action without aggressive stock removal, making it well suited for final finishing passes on sheet metal, tubing, and structural components. It is sold individually and commonly used by sheet metal mechanics, maintenance technicians, and general trade professionals who need a repeatable, low-aggression surface finish.

Installation Notes

Installation is performed by qualified technicians familiar with bench or pedestal grinder tooling. Disconnect and lock out power to the grinder before mounting or removing the brush. Confirm that the spindle speed rating of the grinder does not exceed the rated speed of the brush before operation.
