I agree, I think it could be used as it is, but do think a tang would help
lock the tool.

Again thanks for all the help, if anyone has a use for one of these send me
your address.

That drives the cutting tool of choice, and it's extracted from
the taper socket via the rectangular access hole through the
side of the adapter. Sort of a quick change.

Is it possible the square cross-hole is to engage the driving tang on the
ends of tang-shaft drill bits? That's what it looks like to my novice
eyes.
