3M 7010366465 High Strength Flap Brush 8x1x3 in Medium

Product Description

The 3M 7010366465 is a high-strength flap brush built for aggressive surface cleaning and finishing applications where brush longevity and consistent abrasive action matter. Individual nonwoven abrasive sheets are adhered at a 90-degree angle to the core, creating an open flap construction that allows each sheet to flex and conform to irregular surfaces. The abrasive mineral is aluminum oxide at a medium grade, and the brush is rated as medium hardness at a density of 5. At 8 inches in diameter, 1 inch in face width, and 3 inches in arbor hole size, this brush fits standard bench-mounted or pedestal grinder setups common in trade shops and fabrication environments.

This flap brush is suited for heavy-duty cleaning, deburring, blending, and surface preparation on metal, weld seams, and other industrial substrates. The medium-grade aluminum oxide abrasive handles scale removal, rust, and surface contaminants without loading up quickly. Typical users include maintenance technicians, pipefitters, welders, and metal fabricators who need a durable rotary abrasive tool for repetitive, high-contact work cycles.

Key Features

• Individual abrasive sheets adhered at 90 degrees to the core for flexible, conforming contact
• Medium-grade aluminum oxide abrasive mineral for aggressive material removal
• Medium hardness, density 5 construction balances cut rate and brush life
• 8 inches x 1 inches x 3 inches sizing fits standard grinder arbors
• Open flap design resists loading on dirty or scaled surfaces

Compatibility

Designed for use on bench grinders and pedestal grinders with a 3-inch arbor configuration. Suitable for metal surface preparation, deburring, and weld blending applications.

Installation Notes

Installation should be performed by a qualified technician familiar with rotary abrasive tooling. Confirm the grinder RPM rating does not exceed the maximum rated speed of the brush before mounting. Power down and lock out the grinder before mounting or removing the brush. Inspect the flap brush for damage before each use and do not use a brush that shows signs of delamination or core damage.
