Claire M. ★★★★★

Finally got these in for my shop and the knotted cup design chews through carbon steel rust way faster than the old wire wheels I was using. The ¼" shaft fits my angle grinder perfectly and it hasn't thrown a single knot yet.

Isabella ★★★★★

The knot density on this 3-inch cup is solid for the price, and the 1/4" arbor fit my grinder without any adapter hassle. It chewed through carbon steel scale faster than I expected, though it does shed a few bristles on the first pass.

Grace H. ★★★★★
