3M 7010366070 Finishing Flap Brush 8x3x3 in

Product Description

The 3M 7010366070 is a finishing flap brush designed for light-duty cleaning and surface finishing applications. Individual abrasive sheets are adhered at a 90-degree angle to a central core, creating a flexible flap action that conforms to irregular surfaces. The brush measures 8 inches in length with a 3-inch face width and 3-inch arbor hole size. It uses a fine-grade aluminum oxide abrasive mineral with a medium hardness density rating of 5A. This tool is suited for technicians and tradespeople who need consistent, controlled finishing action on metal, wood, or composite surfaces without aggressive material removal.

This flap brush is used in light finishing, deburring, blending, and surface preparation tasks across fabrication shops, maintenance facilities, and field service environments. Its fine aluminum oxide construction makes it appropriate for final-pass cleaning and cosmetic finishing where surface integrity must be maintained. It is sold individually and is compatible with standard bench grinders, angle grinders, and arbor-mounted drive systems that match its 3-inch arbor dimension.

Key Features

• Fine-grade aluminum oxide abrasive mineral for controlled, light material removal
• Individual sheets adhered at 90 degrees to core for flexible, conforming flap action
• Medium hardness density (5A) balances cut rate and surface finish quality
• 8 inches x 3 inches x 3 inches dimensions suit standard arbor-mounted grinder setups
• Light-duty design minimizes risk of surface damage during finishing passes

Compatibility

Designed for use with arbor-mounted bench grinders and angle grinder configurations accepting a 3-inch arbor. Intended for light-duty finishing and cleaning applications on metal, painted, and composite surfaces.

Installation Notes

Installation and mounting should be performed by a qualified technician familiar with rotating abrasive equipment. Always power down and disconnect the grinder or drive unit before mounting or removing the flap brush. Confirm that the drive tool RPM rating meets or exceeds the brush RPM rating before operation. Follow applicable ANSI B11 and OSHA standards for abrasive wheel and brush use, including appropriate eye and face protection.
