use cutting oil, don't run the drill too fast in order to keep the bit as cool as possible. Perhaps use left hand drill bits... thought I question the helpfulness of them. Take time to center punch and start with a small bit, work your way up, in order to keep the hole as centered as possible. Get ready to cuss a lot.
