3M 7000120878 Finishing Flap Brush 6x1x2 in

Product Description

The 3M 7000120878 is a finishing flap brush designed for light-duty cleaning and surface finishing work. Individual abrasive sheets are adhered at a 90-degree angle to a central core, creating a flexible flap configuration that conforms to irregular surfaces. The abrasive mineral is very fine grade aluminum oxide, rated at density 5 with medium hardness. Measuring 6 inches in diameter by 1 inch wide with a 2-inch arbor hole, this brush suits bench grinders and pedestal-mounted finishing equipment. It is sold individually and intended for professional finishing trades, fabrication shops, and maintenance technicians requiring a consistent, light-cut finishing action.

This flap brush is suited for light cleaning, deburring, and surface conditioning applications on metal, composites, or similar materials. The very fine aluminum oxide mineral produces a smooth, uniform finish appropriate for final-pass surface prep, light oxide removal, or pre-coating conditioning. It is a practical choice for shops where controlled, repeatable finishing is required without aggressive stock removal.
