WEILER USA 와이어 브러시, 직경 1인치 x 생크 1/4인치, 크림프 와이어 0.020, 최대 RPM 20,000

This little brush fits perfectly in my hand drill and the crimped wires do a great job cleaning rust out of tight spots. The 1/4 inch shank held securely without any wobble even at higher speeds.

I needed a brush that could handle 20,000 RPM without flying apart, and this one holds up perfectly on the die grinder. The crimped wire gives just enough aggression for cleaning rust without gouging the base metal.

The .020 wire bristles are stiff enough to really dig into rust without flying apart, even at high RPM on my bench grinder. The crimped texture grabs into crevices much better than the twisted wire brushes I've used before, and the 1/4" shank fits my drill chuck without any adapter fuss.
