Thanks everyone, but it was only one part and has now been sent out to do. I took the easy route: identifying the desired dimensions/specs and letting the shop we sent it to determine how best to achieve it.
Thanks. For various reasons I am restricted to internal for this one application only. I'll do a little browsing on EDM, since I only know vaguely what it is.
Thank you both! The rotary broaching site is very informative. I don't have experience with EDM so this may sound ignorant, but can it be controlled closely enough to create an accurate internal square drive within the same tolerances as broaching?

Newbie here. Anyone have any experience broaching an internal square drive (1/2") in the end of a 17-4 PH stainless steel threaded shaft? The 2" shaft currently has a 1.5" hex drive on the end of it, but due to interference with another part needs to be cut off and an internal drive put in it...
