If this works out for your job, you could try the old gunsmith's trick,
which is to chuck a nail with a rounded point in the drill press and heat
the spot with friction. You don't have to get it red -- going through all
the shades of blue will do it. Then you can drill it with a good HSS bit.

Of course, it depends on how thick the material is, and whether you can
tolerate softened edges on the hole.

But if I've already taken it up to red hot, and it still won't drill, I
don't think this is going to help much.

Oh, and this is how they turned out:
