Chris:
It sounds like you have reach the limit of what that fine machine tool,i.e.,
your cold chisel, can do.  Drill a pilot hole of an 1/8" diameter or so on
the centerline of the wheel stud as accurately as you can.  If you have
doubts of your ability to aim the drill, have a helper aid you with the
sighting.  Drill the pilot hole to a depth below the nut without going
through the stud completely (even if you poke through, you'll probably not do
much damage unless you are a madman about it).  Now, keep enlarging the pilot
hole with progressively larger drills until either the wheel nut is spinning
on the end of the drill or the stud is thin enough to be wrung off with a
pair of ViceGrips.

A die grinder will also do the job but, it is difficult to keep from bitching
up the wheel with that approach.  Either way, resign yourself to the fact
that you will have to press in a new wheel stud.
