3M 7010364308 Brite Cut Polish Flap Brush 8x2x4 in 7A Med

Product Description

The 3M 7010364308 is a Brite Cut and Polish Flap Brush engineered for surface finishing applications that demand higher-luster results. The brush is built with individual abrasive sheets adhered at a 90-degree angle to a central core, a construction that delivers consistent cut action across the working face. At a 7A density rating, the brush runs hard, which extends service life and limits conformability to the workpiece. The abrasive mineral is medium-grade aluminum oxide, suitable for cutting and polishing metal, composites, and similar industrial surfaces. At 1.9 pounds, the brush is substantial enough for sustained production use. Overall dimensions are 8 inches x 2 inches x 4 inches.

This flap brush is intended for heavy-duty finishing operations where a standard-density or soft-configuration brush would wear too quickly or fail to achieve the required surface finish. Typical applications include deburring, blending, and polishing on flat or contoured workpieces in fabrication, manufacturing, and maintenance environments. The medium-grade aluminum oxide mineral makes it appropriate for intermediate finishing passes where aggressive stock removal has already been completed.

Key Features

• Individual abrasive sheets set at 90 degrees to the core for consistent cut and finish
• Hard 7A density rating for extended service life and low conformability
• Medium-grade aluminum oxide abrasive mineral for reliable cut and polish performance
• Heavy-duty construction suited to high-polish finish requirements
• Compact 8 inches x 2 inches x 4 inches form factor for production use

Compatibility

Designed for use on compatible bench-mounted or arbor-driven rotary finishing equipment that accepts a 4-inch arbor hole configuration; verify spindle speed ratings and arbor fit before mounting.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with rotary abrasive tooling. Always power down and lock out the drive machine before mounting or removing the brush. Confirm that the machine spindle speed does not exceed the maximum rated RPM marked on the brush or its packaging. Wear appropriate personal protective equipment, including eye protection and gloves, during mounting and operation.
