Up for sale is a KDK-100 quick change tool post and a handful of holders (both KDK and Phase II modified to fit). These have been used on my lathe, but I've switched over to the same tool post we use at work and no longer need this one. Here's what I have. KDK-105 Boring Bar Holder (ø1.00).
Phase II 250-204 Boring Bar Holder ø1.00 w/ ø. Phase II 250-205 #2 Morse Taper. Phase II 250-201 Turning & Facing. Phase II 250-210 Knurling, Turning & Facing. Mystery Boring Bar Holder Unmarked, and a bit hacked up...
This is shown in the last two pics. Not shown in the pics is the t-slot nut and mounting bolt for the KDK, which I will include. These are obviously used tools, but worked great for the short time I've owned them.
