Like Dan G said- use your drill as though it were a reamer. Just
predrill first with a drill that's .005 to .010 undersize and then
follow up with your final drill size.

Hmm, you tried that? Or is this just what you imagine? In my experience,
drills cannot ream. You can't use such a small step up in drill size, it
won't cut, it just rubs and smears the metal. That's why there has to be
reamers for reaming.
