3M 7010329143 Finishing Flap Brush 12x1x5 Inches Medium

Product Description

The 3M 7010329143 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 the core, creating a flap-style configuration that delivers consistent contact across the work surface. The brush uses medium-grade aluminum oxide as its abrasive mineral, making it effective on metal, composites, and similar materials. The hard 7-density construction provides long service life and low conformability, meaning the brush maintains its shape under load rather than flexing into contours. At 1.38 pounds, it is sized for use on bench-mounted or handheld rotary equipment.

This flap brush is suited for general cleaning, deburring, light stock removal, and surface finishing in fabrication, maintenance, and light industrial environments. The 12-inch face width combined with the 1-inch arbor hole and 5-inch trim makes it a practical choice for production finishing lines or maintenance shops requiring consistent surface prep results on flat or slightly irregular workpieces.

Key Features

• Medium-grade aluminum oxide abrasive mineral for effective light-duty finishing
• Individual sheets adhered at 90 degrees to core for uniform flap action
• Hard 7-density construction for extended service life and low conformability
• 12-inch face width for broad surface coverage per pass
• Designed for cleaning and finishing applications on a range of substrate materials

Compatibility

Designed as a direct-mount finishing flap brush for rotary bench or floor equipment accepting a 5-inch trim configuration and standard arbor mounting.

Installation Notes

Installation should be performed by qualified maintenance or shop personnel familiar with rotary abrasive tooling. Power down and lock out the drive equipment before mounting or removing the brush. Confirm that the spindle speed of the host machine does not exceed the maximum rated RPM marked on the brush. Wear appropriate eye and face protection during operation as required by ANSI and shop safety standards.
