ok, now that I've said it - I have this Abene mill - it has a #40
taper, so I bought a pile of #40 tool holders. Some (about 2 out of
5) work properly, the remainder have the wrong draw bar thread. So,
I'm imagining that I have two different types of holders - it seems by
looking around that BT and CAT are the same except for drawbar thread
(metric for BT, inch for CAT) -- is this correct?

If yes, anyone wanna trade?

Its not only the tread is different, the design of the ring that the
toolchanger grabs is different too. Are you looking for BT or Cat 40?

I *think* that his mill is not CNC, and thus does not have a
toolchanger. For that, just making alternate drawbars should be
sufficient.

Enjoy,
