Julian A. ★★★★★

Went through an old trailer frame with this knotted cup brush and it ripped through the rust scale way faster than any wire wheel I've used before. The 5/8"-11 arbor made swapping it onto my grinder a breeze.

Jacob A. ★★★★★

The stainless steel bristles on this cup brush are holding up really well against heavy rust on some old steel beams I'm cleaning up, and the 5/8"-11 arbor was a perfect fit for my grinder. It's definitely aggressive, but it gets the job done fast.

Olivia ★★★★★

The knotted stainless steel bristles really tore through the carbon steel rust on my trailer hitch without losing their shape. The 5/8"-11 thread fit my angle grinder perfectly, and the 3" cup covered a good amount of surface in one pass.
