Claire T. ★★★★★

Installed these on my lathe and the 14 tpi pattern cut perfectly into mild steel on the first pass. The 3/4" diameter feels solid and the 1/4" shaft fit snug without any wobble.

Brian A. ★★★★★

The 14 lines per inch came out clean and sharp on my first try, and the 3/4" diameter fit my holder without any fiddling. I've put them through a few tough jobs already, and the steel is holding up nicely.

Scarlett ★★★★★

14 lines per inch is exactly what my knurling job needed, and the hardened steel edges bit into the aluminum clean on the first pass. The 3/4" diameter fits my holder perfectly, no wobble. These are going to last me a long time.
