Customer Reviews (4.8 / 5 · 5 reviews)

Grace S. ★★★★★

Finally, a chuck that actually centers bits accurately on my mini mill—the hardened ground jaws made a noticeable difference in my last project. It holds securely down to 1/32" without slipping.

Harper ★★★★★

The hardened jaws on this chuck grab bits securely and run noticeably truer than my old one. It was a simple swap on my mini mill and the alignment is spot-on.

Mia ★★★★★

Swapped out the cheap chuck on my mini mill for this one – the R8 arbor slid right in with no wiggle. It holds a 3/8" drill bit dead straight, which solved my alignment headaches.
