3M 7100126832 Flap Brush 8x2x3 Medium Aluminum Oxide

Product Description

The 3M 7100126832 is a Brite Cut and Polish Flap Brush engineered for applications that demand higher-polished surface finishes. Individual abrasive sheets are adhered at a 90-degree angle to the core, creating a flap-style construction that delivers consistent contact across the work surface. The brush uses medium-grade aluminum oxide as the abrasive mineral and carries a hard density rating of 7, which supports long service life while limiting conformability on irregular surfaces. At 1.96 pounds, it is a heavy-duty tool suited for production-level grinding and polishing tasks on metal and similar substrates.

This flap brush is used in industrial and trade settings where surface finishing, deburring, or polishing is required on metal workpieces. The 8-inch diameter, 2-inch face width, and 3-inch arbor hole size make it compatible with standard bench grinders and pedestal-mounted finishing machines. It is well suited for fabrication shops, maintenance facilities, and manufacturing environments where repeatable, higher-gloss surface results are expected. The medium-grade abrasive makes it appropriate for intermediate finishing work between aggressive stock removal and fine polishing stages.

Key Features

• Individual abrasive sheets adhered at 90 degrees to core for consistent flap contact
• Medium-grade aluminum oxide abrasive mineral for intermediate finishing
• Hard density rating of 7 for extended service life and low conformability
• 8-inch diameter x 2-inch face width x 3-inch arbor hole construction
• Heavy-duty build suited for production polishing and deburring applications

Compatibility

Designed for use on standard bench grinders and pedestal finishing machines accepting an 8-inch diameter flap brush with a 3-inch arbor hole. Verify spindle speed rating and arbor size on the host machine before mounting.

Installation Notes

Installation should be performed by qualified personnel familiar with abrasive wheel mounting procedures. Always power down and lock out the grinder or finishing machine before mounting or removing the brush. Inspect the brush for damage before each use and confirm the machine spindle speed does not exceed the rated maximum for the brush. Follow applicable ANSI B7.1 safety standards for the mounting and use of abrasive products.
