The Industrial Manganese Wire Brush Set 7pc use tough, durable 65 manganese wire and are produced on fully automated equipment, ensuring consistent wire distribution and wire formation (crimped, knotted and twisted). The brushes feature heavy-duty backing plates and are precision balanced ensuring vibration-free action which reduces user fatigue. 3" (76 mm) Crimped Cup Brush is ideal for fast cleaning of large surfaces that are not perfectly flat. The wire bristles are not knotted so they have some give to them. Use this brush to remove rust, burrs and weld splatter. 3" (76 mm) Knotted Cup Brush is ideal for very aggressive, fast, heavy-duty cleaning of large flat surfaces, removing weld splatter, rust and burrs. 4" (102 mm) Knotted Wheel Brush is designed to very aggressively remove heavy corrosion, rust, paint, weld splatter and scale. It's ideal for cleaning weld edges, deburring metal and paint-readying steel or metal in hard-to-reach, restricted surface areas. 4" (102 mm) Industrial Stringer Bead Knotted Wire Wheel Brush features stiff small knots. It has an extremely narrow tufted face that provides aggressive action. It's ideal for bead weld preparation and excellent for confined areas. 10-1/2" (266.7 mm) Heavy-Duty Hand Scratch Brush is designed for use in hard-to-reach areas that require a narrow face. The 5" (127 mm) length of wire fill is 1" (25.4 mm) wide. The wire fill provides excellent cutting ability and offers a high degree of fatigue resistance. The staple-set wire provides long brush life. The wood handle has a smooth, machined finish and the pre-drilled hang-up hole allows for convenient storage. Includes two spindle nut wire brush converters (M10 x 1.25 and M10 x 1.50) for attachment to different grinders.
