Made from brass-plated wire, cup brushes let you effectively work both flat and curved surfaces. Less aggressive than knotted-wire wheels, they still do a good job on paint and surface rust. The brushes have 1", 2" and 3" diameters (24mm, 50mm and 75mm). All have integral arbors and 1/4" diameter shafts, and are ideal for use in our chuck extender.
