I have an adaptor on my desk that is very strange. It is a Morse #2 to

with Jacobs #5 shank, to Morse #2 tapered anything. Very odd.

Morse tapered drills.
If you have a set of drills - how about J #5 set from 1/16 to 3/4".
Could you pick them up ?

Hmm ... given that the Jacobs taper end of things puts the
socket towards the drill rather than towards the spindle, I can't see a
set of drills with Jacobs tapers, or a need for an adaptor for such.

No -- such adaptors are normally for mounting a drill chuck --
or perhaps something like a tapping head to the spindle of a drill
press, lathe, or milling machine.

Granted, I can't imagine any reasonable need to mount that large
a chuck onto a MT-2 spindle. It would almost certainly spin in the
socket, or if it was held by the tang, it would likely wring off, or
spin the tailstock ram in its socket. :-)

I was pushing it when I used a MT-3 socket to MT-2 shank adaptor
to use MT-3 drills in the tailstock of my lathe -- before I got the
proper tailstock with the MT-3 socket to use my 3/4" to 1" set of
drills.

Enjoy,
