3M 7010292389 Finishing Flap Brush 8x1x3 in Very Fine

Product Description

The 3M 7010292389 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 configuration that delivers consistent contact across the work surface. The brush measures 8 inches in diameter, 1 inch in width, and fits a 3-inch arbor. It uses a very fine grade aluminum oxide abrasive mineral, making it suitable for final-pass finishing where controlled material removal and surface refinement are the goals. At a hard 7 density, the brush resists excessive conforming to surface contours, extending tool life and maintaining consistent cut throughout the wheel's service life.

This flap brush is suited for light cleaning, deburring, and finishing operations on metal, fabricated components, or similar materials in shop or field environments. The very fine aluminum oxide abrasive is appropriate for final finishing passes where surface condition matters. The 3-inch arbor bore fits standard bench grinders and angle grinder setups commonly used by fabricators, maintenance technicians, and industrial trade professionals.

Installation Notes

Installation should be performed by a qualified operator following the grinder manufacturer's mounting instructions and applicable ANSI B11 or OSHA abrasive wheel safety guidelines.
