3M 7010328993 Finishing Flap Brush 8x2x3 in Medium

Product Description

The 3M 7010328993 is a finishing flap brush designed for light-duty cleaning and finishing applications in industrial and trade environments. The brush measures 8 inches in diameter by 2 inches wide with a 3-inch arbor hole. Individual abrasive sheets are adhered at a 90-degree angle to the core, creating a flap-style action that delivers consistent surface contact. The abrasive mineral is medium-grade aluminum oxide, suited for moderate material removal and surface preparation. The hard 7-density construction extends service life and reduces conformability, making it appropriate for flat and near-flat work surfaces.

This flap brush is used in metal fabrication, maintenance, and finishing operations where controlled surface conditioning is required. The medium-grade aluminum oxide abrasive makes it a practical choice for deburring, blending, and light cleaning on steel and other hard materials. It is commonly used by fabricators, maintenance technicians, and industrial tradespeople working on structural components, weldments, and machine parts.
