It might be a little too light-duty for your machine (not familiar with an X3), but I've been quite pleased with the "Tormach Tolling System". http://www.tormach.com/Product_TTS.html Basically it uses a 3/4" straight shank with a locating ring that comes up against the spindle nose to give a repeatable Z. When the 3/4" collet tightens, it draws the ring tight against the spindle nose. They have collets for R8 and MT3 spindles. I was running parts the other evening on my Shoptask machine, and was getting 30 to 35 seconds chip-to-chip for totally manual toolchanges. I didn't like the pricing on the Tormach ER collet chucks, but I ran across another supplier who has nice chucks with 3/4" shanks at very good prices. I got a couple of these and added my own locating rings: http://www.maritool.com/Tool-Holders-Straight-Shank/c23_28/p69/ER20-3/4-2.0-STRAIGHT-SHANK-COLLET-CHUCK/product_info.html I bored the rings and turned the locating face in one chucking, then shrunk them onto the shanks before turning the OD. My collection of TTS tooling (for now - I'm planning to get a couple more collet chucks in the not-to-distant future): http://www.jmkasunich.com/pics/mill-tooling-2012.jpg The two on the left are from Mari Tool with my rings, he other four are from Tormach. I really like the fact that you can simply put a locating ring on anything that has a 3/4" straight shank and use it.
