3M 7010366654 Finishing Flap Brush 12x2x5 in 7A Very Fine

Product Description

The 3M 7010366654 is a finishing flap brush designed for light-duty cleaning and surface finishing applications. Individual abrasive sheets are adhered at a 90-degree angle to a central core, creating a flexible yet structured brush geometry. The abrasive mineral is very fine grade aluminum oxide, suited for fine finishing passes rather than aggressive stock removal. The hard 7A density provides long service life while limiting conformability, keeping the cutting action consistent on flatter surface profiles. At 2.28 pounds, the brush is a manageable size for handheld or arbor-mounted use in production or maintenance finishing work.

This flap brush is built for light-duty finishing and cleaning tasks on metal, composite, or painted surfaces where a consistent scratch pattern and controlled material removal are required. The very fine aluminum oxide abrasive grade makes it appropriate for final-stage surface prep, deburring, blending weld seams, or cleaning oxidized surfaces before coating. It is commonly used by fabricators, maintenance technicians, and industrial finishing professionals working on equipment, structural components, or manufactured parts.

Key Features

• Very fine grade aluminum oxide abrasive mineral for controlled, light material removal
• Individual sheets adhered at 90 degrees to core for consistent flap action
• Hard 7A density for extended service life and low surface conformability
• 12 inches x 2 inches x 5 inches overall dimensions suit standard arbor setups
• Light-duty rating appropriate for finishing, blending, and surface cleaning tasks

Compatibility

Designed as a standard flap brush for use on arbor-mounted angle grinders, bench grinders, or finishing machines accepting a 5-inch bore size at compatible RPM ratings for the brush diameter and density grade.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive product mounting requirements. Always confirm the machine spindle speed does not exceed the maximum rated RPM for the brush before mounting. Power down and lock out the machine before mounting or removing the brush. Inspect the brush for damage before each use and do not use a brush that shows signs of delamination or core damage.
