Sometimes CNC can be the way to go for even a single hole.
Some years back in a sheetmetal shop I worked at, a custome rectangle
punch/die was ordered for a job. Needless to say, it showed up at the
very last minute, and the operator quickly discovered the index pin was
missing, along with the hole! The supervisor brought to me and asked if
there was any way in heck I could put a 1/4" dowel pin in the hardened
die. I hand ground a solid carbide spade drill, programmed a single
through hole with peck increments of .001. Gave it lots of coolant and
walked away. 15 minutes later, we had a perfect thru hole. I'd not have
wanted to stand there pecking a manual machine like that!
