The quill recently stuck in my Hurco KMB1. I pulled it apart (no easy task) and found the quill was badly scored beyond repair. I am in the process of installing a permanent high speed 4th Axis Z on the Hurco. (I would benefit from a larger foot print high speed spindle machine anyway), but I don't want to start unloading all the kwik 200 tool holders I already have. I have a smaller mill (manual) that has an R8 taper. I was thinking if I could find a decent price on a Kwik 200 master holder with an R8 shank I could use all my Kwik 200 tool holders on that machine.
