3M 7010365674 Flap Brush 8x1x3 in Medium Aluminum Oxide

Product Description

The 3M 7010365674 is a cut-and-polish flap brush designed for surface finishing applications that demand higher-grade polished results. Individual abrasive sheets are adhered at a 90-degree angle to a central core, which allows the brush to deliver consistent contact across the workpiece during rotation. The abrasive mineral is medium-grade aluminum oxide, suited for cutting and polishing in a single operation. This brush measures 8 inches in face width, 1 inch in trim width, and mounts on a 3-inch arbor. The hard density rating supports long service life and low conformability, making it appropriate for use on flat or contoured metal surfaces in fabrication and finishing environments.

This flap brush is used in industrial and trade finishing operations where a blend of cutting action and surface refinement is required in one tool. Typical applications include weld blending, deburring, and surface conditioning on metal workpieces. It is suited for use on angle grinders or bench-mounted finishing equipment that accepts a 3-inch arbor. The medium aluminum oxide mineral grade makes it appropriate for general-purpose metal finishing work on ferrous and non-ferrous materials.

Key Features

• Individual abrasive sheets mounted at 90 degrees to core for consistent surface contact
• Medium-grade aluminum oxide mineral for cut-and-polish performance in one pass
• Hard density construction for extended service life and low conformability
• 8-inch face width provides broad surface coverage per pass
• 3-inch arbor mount for compatibility with standard angle grinders and bench finishers

Compatibility

Designed as an OEM-style replacement or direct-fit flap brush for grinders and bench-mounted finishing equipment accepting a 3-inch arbor bore.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with rotary abrasive tooling. Always power down and disconnect the grinder or finishing machine before mounting or removing the flap brush. Verify that the spindle speed rating of the machine does not exceed the maximum rated RPM of the brush before operation. Inspect the brush for damage before each use and replace if sheets are torn, delaminated, or the core is cracked.
