3M 7010330004 Finishing Flap Brush 8x2x3 in Silicon Carbide

Product Description

The 3M 7010330004 is a finishing flap brush designed for light-duty cleaning and surface finishing tasks. Individual abrasive sheets are adhered at a 90-degree angle to a central core, creating a flexible flap configuration that conforms to irregular surfaces and contours. The abrasive mineral is super fine grade silicon carbide, providing controlled material removal suited to final finishing rather than aggressive stock removal. With a medium hardness density rating of 5S, this brush delivers consistent, repeatable results across metal, composite, and similar work surfaces. It is the appropriate tool when the job calls for fine surface preparation or cleanup rather than heavy deburring.

This flap brush is used in light fabrication, metal finishing, and surface conditioning applications. At 8 inches in diameter, 2 inches in width, and 3 inches in arbor bore size, it mounts to bench grinders, angle grinders, or finishing machines suited to that arbor configuration. Typical applications include weld cleanup, scale removal, blending, and pre-paint surface preparation in shop environments. It is well suited to professional fabricators, maintenance technicians, and finishing trades working with metals or similar substrates.

Key Features

• Super fine grade silicon carbide abrasive mineral for controlled, light-duty finishing
• Individual abrasive sheets adhered at 90 degrees to core for flexible surface contact
• Medium hardness density rating of 5S for consistent performance across passes
• 8 inches x 2 inches x 3 inches dimensions for compatibility with standard bench and angle grinding equipment
• Designed for cleaning, blending, and finishing rather than aggressive material removal

Compatibility

Designed as an OEM-style finishing flap brush for use with bench grinders, angle grinders, or power finishing machines that accept a 3-inch arbor bore.

Installation Notes

Installation should be performed by a qualified technician familiar with rotary abrasive tooling. Disconnect and lock out all power to the grinder or finishing machine before mounting or removing the brush. Verify that the machine speed rating does not exceed the rated maximum RPM of the brush before operation. Inspect the flap brush for damage before each use and replace if sheets are torn, separated, or the core is cracked.
