3M 7100097932 Finishing Flap Brush 8x2x3 Medium

Product Description

The 3M 7100097932 is a finishing flap brush designed for light-duty cleaning and finishing applications. Individual abrasive sheets are adhered at a 90-degree angle to a central core, creating a flap-style configuration that conforms to workpiece surfaces. The abrasive mineral is aluminum oxide at a medium grade, and the brush is rated 5A medium density. At 8 inches in length, 2 inches in face width, and 3 inches in arbor hole diameter, it fits standard bench grinder and finishing machine spindles commonly used in fabrication and maintenance shops.

This flap brush is suited for general surface preparation, light deburring, blending, and finishing on metal, wood, or composite materials. The medium hardness and aluminum oxide mineral make it appropriate for removing light oxidation, smoothing welds, or achieving a consistent finish on flat and contoured surfaces. It is commonly used by maintenance technicians, fabricators, and industrial finishing professionals in both shop and field settings.
