Customer Reviews (4.4 / 5 · 5 reviews)

Thomas R. ★★★★★

This knot design really locked onto the weld scale without any skipping—much better control than my old twisted knot cup. Chewed through a rusty beam in about half the time I expected.

Timothy H. ★★★★★

This cup cleaned a heavily rusted trailer hitch in minutes, and the 5/8-11 thread locked on tight without any wobble. Running it at 9,000 RPM feels solid and safe.

Thomas ★★★★★

The knotted .064 wire holds up way better than the cheaper twisted brushes I've tried, and it chews through scale on steel beams without losing its shape. Threaded on tight with the 5/8-11 and gave it hell at 9,000 rpm, zero wobble.
