3M 7010328530 Finishing Flap Brush 6x1x2 Inches Medium

Product Description

The 3M 7010328530 is a finishing flap brush designed for light-duty cleaning and surface finishing tasks. Individual abrasive sheets are adhered at a 90-degree angle to a central core, creating a flap-style geometry that delivers consistent contact across the work surface. The brush uses a medium-grade aluminum oxide abrasive mineral, which provides a reliable cut rate on metals, composites, and coated surfaces. The 7A hard density rating supports long service life while limiting conformability, making it best suited for flat and near-flat surface work. Trades such as metal fabricators, pipefitters, and HVAC sheet metal techs will find this tool well matched to weld cleanup, deburring, and surface prep.

This flap brush measures 6 inches in diameter by 1 inch in width with a 2-inch arbor bore, positioning it for use with bench grinders and angle grinders of the appropriate spindle size. It is suited for light finishing and cleaning passes on mild steel, stainless, and aluminum where a non-woven or structured abrasive action is preferred over grinding wheels or wire brushes. The medium grade makes it appropriate for general-purpose prep work where fine surface conditioning is needed without heavy material removal.

Installation Notes

Installation is performed by a qualified operator familiar with abrasive wheel mounting procedures. Always power down and lock out the grinder before mounting or removing the flap brush. Confirm the grinder's rated RPM meets or exceeds the brush's rated speed before operation, and inspect the brush for damage prior to each use. Refer to ANSI B7.1 safety requirements for the use, care, and protection of abrasive wheels where applicable.
