I still make most of my holes that way. The (rare) exception would
be when I happen to have a hole saw the correct size - or slightly
under size and finish with the half round file. If I had to take
everything to a machine shop or buy the "correct" tool for every
job, I would have no homebrew gear.

Oh for the good old days when we would drill a series if 1/4" holes around
a circle, knock the center out with a hammer and use a half round file to
clean it up.
I still use that technique to make square holes for a blower inlet.
