Victoria ★★★★★

This brush chewed through heavy mill scale on a steel beam like it was nothing, the 0.014 wire is stiff enough to really get in there. The 5/8"-11 arbor threaded right onto my grinder with no fuss. Definitely earning its keep in my shop.

George I. ★★★★★

Took this to a rusted metal gate, and the 0.014 wire really chewed through the scale without bogging down the grinder. The knotted construction holds up better than the twisted brushes I've tried before.

Edward ★★★★★

Used it on a 7-inch grinder and the 5/8"-11 threading spun on perfectly with no adapter fuss. The knotted .014 wires held their shape through a whole afternoon of weld splatter cleanup, which surprised me. Probably the sturdiest cup brush I've owned for the price.
