Whenever we get waterjetted parts the holes are usually clearance holes or tap drill holes and their diameter is not critical. Our guy cuts them slightly undersize then we open them up with the correct size drill.

I know Pink just cuts them slightly undersized and then anything that needs a bearing in it gets opened up with a reamer in a hand drill. I'd never have guessed you could get away with using a hand drill, but it sure works for them.
