3M 7010329829 High Strength Flap Brush 8x2x3 Medium

Product Description

The 3M 7010329829 is a high strength flap brush engineered for aggressive cleaning, deburring, and surface preparation tasks where durability under sustained load is critical. Individual abrasive sheets are adhered at a 90-degree angle to the core, creating a flap-style configuration that delivers consistent cut throughout the life of the brush. The abrasive mineral is medium-grade aluminum oxide, rated at a 5A medium hardness and density. At 1.56 pounds, the brush measures 8 inches in diameter, 2 inches in face width, and mounts on a 3-inch arbor bore. Licensed tradespeople and industrial maintenance technicians reach for this tool when standard wire brushes lack the abrasive bite needed for the application.

This flap brush is suited for metal fabrication, weld cleanup, rust and scale removal, and general surface conditioning on ferrous and non-ferrous substrates. It performs in both bench-mounted and stationary machine setups where a secure 3-inch arbor mount is available. The medium-grade aluminum oxide mineral makes it appropriate for work that demands material removal beyond what a fine-grade finishing brush can provide, without crossing into coarse-grade stock removal territory. Maintenance professionals, pipefitters, and fabricators working in industrial and commercial settings are the primary end users.

Key Features

• Individual abrasive sheets adhered at 90 degrees to the core for consistent flap-style cutting action
• Medium-grade aluminum oxide abrasive mineral for aggressive cleaning and surface prep
• 5A medium hardness and density rating balances durability with conformability
• 8-inch diameter face with 2-inch width and 3-inch arbor bore for stationary machine mounting
• Built for sustained use in applications where durability is a primary requirement

Compatibility

Designed for use on stationary grinders and deburring machines fitted with a 3-inch arbor. Verify spindle speed rating against machine RPM before mounting.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive wheel and brush mounting procedures. Power down and lock out the machine before mounting or removing the brush. Confirm the machine arbor size matches the 3-inch bore and that the rated spindle speed does not exceed the brush maximum RPM. Always install and secure the flanges correctly before powering the machine on.
