BHA Aluminum Oxide Shank Mounted Flap Wheels, 1-1/2” x 1” x 1/4”, 40 Grit - 5 Pack

The 1-1/2" x 1" x 1/4" Mounted Flap Wheel with shank by Black Hawk Abrasives are the ideal choice for polishing, flash removal, light grinding, deburring, scale removal, blending, and graining in small spaces, such as the inside or outside of pipes or tubes. These flapper wheels are made up of aluminum oxide abrasive flaps that are arranged in a fan pattern around the straight spindle shank of the flap wheel. This fan design allows the premium, x-weight, abrasive cloth to wear away during use, exposing new aluminum oxide abrasive grains. This action of providing a continuous supply of fresh aluminum oxide grains results in consistent grinding throughout the use of the flap wheel. Additionally, the flap design allows flexibility so that the wheel can contour around work pieces and smooth rounded or irregular shaped surface.
