My Starrett 165 arrived today.
You won't be disappointed. The whole thing is just more precisely made than your average hobby store pin vise. The collets, the threaded nose that goes over the collets, the handle, are all heavy and operate smoother. The 4 jaws of the collet are in a dead-straight cross that closes dead-on in the middle, and however the metal is tapered in that collet, it gets a wonderful "grab" on the bit without having to crank on the nose to keep the bit from slipping.
It's a darn nice tool.
