3M 7010364283 Finishing Flap Brush 8x2x3 in Fine Aluminum Oxide

Product Description

The 3M 7010364283 is a finishing flap brush designed for light-duty cleaning and finishing applications across metal, wood, and composite surfaces. Individual abrasive sheets are adhered at a 90-degree angle to a central core, creating a flap-style action that delivers consistent surface contact and controlled material removal. The brush uses a fine-grade aluminum oxide abrasive mineral, well suited for final-pass finishing and light surface prep. A hard 7-density construction extends brush life and limits conformability, keeping the cut pattern predictable on flat and near-flat workpieces. Measuring 8 inches in diameter by 2 inches wide with a 3-inch arbor, this brush mounts to bench grinders and pedestal units used in fabrication and maintenance shops.

This flap brush is intended for light cleaning, deburring, and finishing passes where a consistent scratch pattern is required. It is commonly used in metal fabrication, HVAC duct work, general maintenance, and light industrial finishing environments. The fine aluminum oxide mineral makes it appropriate for final finishing stages rather than aggressive stock removal. The 8-inch diameter suits standard bench grinder arbor setups found in trade shops and field service operations.

Key Features

• Fine-grade aluminum oxide abrasive mineral for controlled, consistent finishing
• Individual flap sheets adhered at 90 degrees to core for even surface contact
• Hard 7 density rating provides long service life and low conformability
• 8 inches x 2 inches x 3 inches sizing fits standard bench grinder arbors
• Light-duty rated for cleaning and finishing, not heavy stock removal

Compatibility

Designed for use on bench grinders and pedestal grinders accepting a 3-inch arbor bore with an 8-inch wheel diameter. Suitable for metal, wood, and composite surface finishing applications in light industrial and trade settings.

Installation Notes

Installation should be performed by a qualified technician familiar with bench grinder tooling and ANSI B7 wheel mounting guidelines. Power down and lock out the grinder before mounting or removing the brush. Inspect the flap brush for damage before each use and confirm the arbor nut is properly tightened to the manufacturer specification for the grinder being used. Always use appropriate eye and face protection when operating rotary abrasive tools.
