Collet Chuck, ER-32, 3MT

The 3MT shank seated perfectly in my mini lathe spindle with no wobble, and the included spanner makes tightening collets painless. Runout on my end mills is way better than the old drill chuck ever managed.

Swapped this ER-32 chuck onto my mini mill and the runout is basically nonexistent, which I wasn't expecting at this price. The included spanner wrench actually fits the nut properly instead of slipping like the one that came with my old setup. Drawbar threaded right in with the 3/8"-16, no fuss.

The 3MT shank seats perfectly in my mini lathe spindle with no wobble, and runout on a half-inch end mill was barely measurable. The included spanner fits the nut snugly, which I didn't expect at this price. Drawbar threads matched my 3/8"-16 rod without any fuss.
