Abrasive brushes are made of coarse strands of material and are used with power tools to polish, debur, clean, and buff surfaces, as well as to remove rust, scale, paint, and welding spatter. Paints, stains, adhesives, and rust are removed from surfaces using abrasive radial discs and brushes. Hard-to-reach places and curved or angled surfaces are cleaned and smoothed with wire cup brushes. Disc brushes are used to debur and remove rust from wide flat areas. End brushes are used to polish or clean small sections of a tool or die. Blind and threaded holes are deburred and cleaned with spiral and tube brushes. Wheel brushes remove paint and corrosion off surfaces with high-strength, vigorous brushing.
