This wire cup brush is designed for light to medium-duty work and delivers rapid stock removal from a wide variety of surfaces. The bristles are made from hardened dipped brassed steel wire, which gives a high level of durability and resistance to oxidation. The brush is strong enough to provide reliable performance, and the crimping is flexible to tackle recessed areas and irregular surfaces. The cup shape works flat to the surface to cover a large surface area. Compatible with most angle grinders with an M14x2 connection.
