There is actually a special-made drill bit for exactly such an
operation. I have used it for exhaust manifold studs gone wrong.

It is a reverse-twist bit. You use a dental burr chucked into a
Dremel to indent the top of the stud. Then apply the drill bit with
the drill set to "reverse." Now, this is after a couple of days
soaking with a penetrating oil. I have always been able to get the
job done this way. It may not work in this case, but it's worth a
shot.
