3M 7000121151 Scotch-brite Cut Polish Flap Brush Med

Product Description

The 3M 7000121151 is a Scotch-Brite Cut and Polish Flap Brush designed for surface finishing, deburring, and blending operations on metal, wood, and composite materials. Measuring 2 inches in diameter by 1 inch in width with a 0.25-inch arbor hole, this medium-grit flap brush combines abrasive nonwoven material with a flexible flap construction that conforms to contours and edges. It is sold in cases of 25 units, making it practical for shops and field crews that cycle through abrasive tooling regularly. Maintenance technicians, fabricators, and pipefitters commonly use this brush for weld blending, surface prep, and light stock removal.

This flap brush is suited for use on handheld or bench-mounted rotary tools and right-angle grinders that accept a 0.25-inch shank. Typical applications include surface conditioning prior to coating or inspection, edge breaking on machined components, and removing light oxidation or scale from metal surfaces. The medium grit designation makes it appropriate for moderate material removal while leaving a consistent surface finish suitable for downstream finishing steps.

Compatibility

Installation Notes

Installation and mounting should be performed by a qualified technician familiar with abrasive tooling safety practices.
