Weiler 12776 Knot Wire Cup Brush, 4" Single Row, 0.20" Bronze, 5/8"-11 UNC Nut

Wire cup brushes are intended primarily for use on portable power tools for addressing larger surface areas more efficiently than a wheel brush. Cup brushes featuring a threaded nut are designed for smooth, efficient operation on angle grinders to make quick work of large jobs. Utility cup brushes featuring a permanently attached 1/4" stem are more suitable for smaller jobs and are recommended for use on high speed air tools for the most effective brushing action and longest life. Cup brushes are manufactured with individual knot hole and solid ring construction for high performance and long life. Single row knot wire cup brushes provide heavy-duty brushing action with some flexibility.
