The molded, flexible bristles are filled with proprietary 3M™ Ceramic Abrasive Grain to provide a high quality finish with minimal pressure. Use the brush to effectively clean, finish, polish and deburr irregular surfaces. Replace Wire Brushes, Use Less Pressure Scotch-Brite™ Radial Bristle Brush Replacement Discs provide more surface contact than wire brushes and maintain abrasiveness throughout the life of the brush. Moreover, the Scotch-Brite™ Radial Bristle Brush provides a safer alternative to wire brushes by eliminating the risk of flying wires being ejected from the brush. Under normal use, the flexible bristles remain safely in place and can achieve the desired finish using light pressure. Applications Bristle brush discs feature firm yet flexible bristles that produce uniform finishes around protrusions, detail grooves, patterns and other hard-to-reach areas. They conveniently remove paint, stains, adhesives, weld burns, rust, heavy oxides, and surface contaminants. The discs work well on aluminum, brass, bronze, carbon steel, cast iron, stainless steel, and other metals. Applications include general industrial, aerospace, automotive, metalworking and transportation as well as fine detailing requirements of electronics, jewelry and woodworking industries.
