3M 7100062947 Finishing Flap Brush 8x2x3 Inches

Product Description

The 3M 7100062947 is a finishing flap brush designed for light-duty cleaning and surface finishing applications. The brush is built around a central core with individual abrasive sheets adhered at a 90-degree angle, creating a conformable, flexible action that follows irregular contours and curved surfaces. The abrasive mineral is fine-grade aluminum oxide, rated at a soft, conformable density suitable for finishing work rather than aggressive stock removal. Trade professionals use this brush for deburring, blending, and light surface prep where a consistent finish is the goal.

This flap brush is suited for use in fabrication, maintenance, and finishing environments where light cleaning or surface conditioning is required. The 8-inch diameter by 2-inch face width and 3-inch arbor hole size make it compatible with bench-mounted or pedestal grinding setups commonly found in metalworking shops, HVAC fabrication facilities, and general industrial maintenance operations. It is sold as an individual unit.

Key Features

• Fine-grade aluminum oxide abrasive mineral for controlled finishing and light material removal
• Individual sheets adhered at 90 degrees to the core for flexible, conformable contact
• Soft density construction conforms to irregular and curved workpiece profiles
• 8-inch diameter face provides broad surface coverage per pass
• Lightweight at 1.05 pounds, reducing spindle load during operation

Compatibility

Designed as an OEM-style replacement or direct-fit finishing flap brush for bench grinders and pedestal grinders accepting a 3-inch arbor configuration.

Installation Notes

Installation and operation of flap brushes should be performed by qualified personnel familiar with abrasive wheel safety. Always power down and disconnect the grinder before mounting or removing the brush. Verify that the machine spindle speed does not exceed the maximum rated RPM marked on the brush or packaging. Eye protection and appropriate PPE are required during operation per applicable ANSI and OSHA abrasive wheel standards.
