My Enco and KBC orders arrived on the same UPS truck. When it came
time to try the KBC toolholder on the Aloris AXA, I found that it does
not work. The depth of the dovetail in the toolholder is too deep by
about 1/8th of an inch. It rattles on the toolpost.

This appears to be a good rule of thumb - do not mix piston and
wedge toolholders.
