I have one regular and one heavy-duty "flying parts" or whatever

I'd rather try something like this...

Can you tell what sort of shank it has? I doubt square will work.
Round might work. I would prefer hex.
Any suggestions for a 40 mm aluminum hole saw, to be stuck in a
drill press?
Thanks.
I have a couple sets of these. What you are looking for is an Annular
Cutter:

Dont bother trying to use these with a hand drill. A mill or good
solid drill press. Not! a Harbor Freight caca one either.
Ive used these to punch a hole in 1.5" 4130 plate in just a couple
minutes.

While I love annular cutters for use in the lathe and BP the 3/4" shank
may be a problem for the OPs requirements so a simple hole saw such as a
Starrett bi-metalĀ* hole saw would be more than adequate. Such as
