1/4" Shank

Meant for use in die grinders, drills, and drill presses, our 1/4" shank wire cup brushes are meant for removing rust, scale paint, weld scale, and general metal surface prepartion. There are two styles of cup brushes, crimped and knotted. Crimped wire brushes are just carbon steel wires and knotted wire brushes are twisted carbon steel wires to make a more heavy-duty brush that will last longer.
