3M 7010328770 Brite Cut Polish Flap Brush 7A Medium

Product Description

The 3M 7010328770 is a Brite Cut and Polish Flap Brush designed for surface finishing applications that demand higher polished results. Individual abrasive sheets are adhered at a 90-degree angle to a central core, creating a flap-style configuration that delivers consistent cut and polish action. The brush carries a hard 7 density rating, which supports long service life while limiting conformability to the workpiece surface. The abrasive mineral is medium-grade aluminum oxide, suited for material removal and finishing in demanding environments. At 0.65 pounds, the brush measures 6 inches x 1 inches x 2 inches and is sold individually. This tool is used by machinists, fabricators, and finishing technicians working on metal or composite surfaces.

This flap brush is intended for applications where a higher-gloss or polished surface finish is the end goal rather than aggressive stock removal. The hard 7A density makes it well-suited for flat or mildly contoured workpieces where controlled conformability is preferred. Typical use cases include deburring, blending, and surface preparation on metal components in industrial or shop environments. It is compatible with standard arbor-mounted setups on bench grinders, pedestal grinders, or similar rotary finishing equipment.

Installation Notes

Mounting and operation should be performed by qualified finishing technicians or machinists familiar with rotary abrasive equipment. Always power down and disconnect the grinder or finishing machine before mounting or removing the brush. Verify that the machine spindle speed does not exceed the maximum rated RPM for the brush before operation. Wear appropriate PPE including eye protection and gloves when operating rotary abrasive tools.
