3M 7000120563 Finishing Flap Brush 8x1x3 in

Product Description

The 3M 7000120563 is a light-duty finishing flap brush designed for cleaning and finishing applications on metal, wood, and composite surfaces. The brush measures 8 inches in diameter, 1 inch in face width, and has a 3-inch arbor hole. Individual abrasive sheets are adhered at a 90-degree angle to the core, which allows each sheet to flex and conform to the workpiece surface. The abrasive mineral is very fine grade aluminum oxide, and the brush is rated at a 5A density with medium hardness. Installers and fabricators in HVAC, plumbing, and general metalworking use this brush for surface prep and light deburring.

This flap brush is suited for light-duty surface conditioning, cleaning, and finishing passes on pipe ends, fittings, sheet metal edges, and similar components. The very fine aluminum oxide mineral makes it appropriate for final finishing stages where a smooth, clean surface is required before assembly or inspection. It is used by trade professionals in fabrication shops, mechanical rooms, and field service environments wherever a controlled, consistent finish is needed without aggressive stock removal.

Key Features

• Individual abrasive sheets adhered at 90 degrees to the core for flexible surface contact
• Very fine grade aluminum oxide abrasive mineral for light finishing and cleaning
• Medium hardness 5A density rating for controlled, consistent cut

Designed for use on standard arbor-mounted bench grinders and flap brush tools accepting a 3-inch arbor. Suitable for light-duty cleaning and finishing on metal, wood, and composite workpiece materials.

Installation Notes

Mounting and operation should be performed by a qualified technician familiar with rotary abrasive tools. Verify the tool spindle speed does not exceed the maximum RPM rating marked on the brush before mounting. Power down and lock out the grinder or arbor tool before installing or removing the brush. Always confirm the arbor diameter matches the brush bore before applying torque to the fastener.
