Emily O. ★★★★★

The 5/8"-11 threaded arbor screwed right onto my grinder without any wobble, and the knotted wire design held up well against heavy rust. I got the two-pack so I have a spare ready to go.

William F. ★★★★★

This cup brush chewed through thick mill scale on a steel beam without losing a single wire knot. The 5/8"-11 arbor fit my grinder perfectly and the .020 wire gives just the right stiffness for aggressive cleaning.

Alexander C. ★★★★★

Tackled some heavy surface rust on a metal gate with this cup brush. The knotted wires held up well and the 5/8”-11 arbor fit my grinder perfectly.
