3M 7010309591 Brite Cut Polish Flap Brush 8x2x4 in 5A Med

Product Description

The 3M 7010309591 is a Brite Cut and Polish Flap Brush engineered for heavy-duty surface finishing applications that require a higher level of polished output. The brush measures 8 inches in diameter, 2 inches in face width, and mounts on a 4-inch arbor. Individual abrasive sheets are adhered at a 90-degree angle to a central core, which allows each flap to flex against the workpiece and deliver consistent, even contact. The abrasive mineral is aluminum oxide at a medium grade, and the brush is rated at 5A medium hardness density. It is suited for metalworking, fabrication, and finishing trades where surface prep and polish are part of the same operation.

This flap brush is intended for use in applications that call for cutting and polishing in a single pass, reducing steps in production or maintenance workflows. It is well-suited for use on metal surfaces in manufacturing, welding fabrication shops, and industrial maintenance environments. The medium-grade aluminum oxide construction makes it appropriate for ferrous and non-ferrous metals where a controlled, refined finish is required without aggressive stock removal.

Key Features

• Individual abrasive flaps adhered at 90 degrees to core for consistent workpiece contact
• Medium-grade aluminum oxide abrasive mineral for balanced cut and polish action
• 5A medium hardness density rating for heavy-duty finishing applications
• 8-inch diameter face supports broad surface coverage per pass
• Combines cutting and polishing action to reduce finishing steps

Compatibility

Designed for use on stationary or bench-mounted arbor equipment accepting a 4-inch arbor bore, commonly used in metalworking and fabrication finishing applications.

Installation Notes

This flap brush is installed and operated by metalworking and fabrication professionals on powered arbor equipment. Before mounting, ensure the machine is fully de-energized and locked out per applicable safety procedures. Verify that the arbor diameter and rated operating speed of the equipment are compatible with this brush before use. Always use appropriate guarding and personal protective equipment when operating rotary abrasive tools.
