Ellie G. ★★★★★

I've been using this cup on stainless for a few days now and the 2 3/4" size feels just right for getting into tight spots without losing aggression. The 12,500 max RPM rating gives me confidence to push it on the grinder, and the wire hasn't shed a single bristle yet.

Henry ★★★★★

The .014 wire on this cup gives a nice aggressive cut on stainless steel without feeling too harsh. I've been using it on some welds and it holds up well at high RPM without flying apart.

Henry R. ★★★★★

The 5/8"-11 arbor threaded on perfectly with no wobble, and the 12,500 max RPM rating gives me peace of mind on the grinder. This knotted cup chewed through a stainless weld seam in one pass, and the .014 wire held its shape without shedding bristles.
