Cup Brushes

Cup brushes clean, debur, and polish flat or curved parts and surfaces. They're commonly used on large areas to remove rust, paint, and scale. Their cup-shaped base holds the bristles in a ring to provide a wide area of surface contact. Connect cup brushes to an angle grinder, die grinder, drill, or other power tool to rotate the brush. Crimped wire cup brushes are for light cleaning and polishing while knot wire cup brushes are for aggressive cleaning and deburring.
