Zoe ★★★★★

Finally, a knurl that cuts cleanly without chattering on my small lathe. The 21 lines per inch are precise and consistent across the full width.

Brian P. ★★★★★

I needed a medium diamond knurl for a shaft repair, and the 3/4" diameter fit perfectly in my holder. The 21 lines per inch pattern cut cleanly into mild steel on the first pass, no skipping or chatter.

Ella Y. ★★★★★

The 21 lines per inch pattern pressed cleanly into mild steel on the first pass, no slipping or chatter. The 3/4" diameter and 1/4" shaft hole fit my tool post holder perfectly, and the diamond finish leaves a precise, grippy texture that feels factory-made.
