If he is trying to hold .002" oversize, an oversized drill is going to be
much less predictable, probably more difficult to find and a good bit more
expensive.


The key is the type of bit he is advocating dressing and using.

A wood cutting Forsner style drill bit eliminates any possible springback,
as it cuts only on a straight line from the center to the diameter, and
pretty much level across the hole. It has no flutes to try to dress, and a
small area to dress. It is the ideal bit to re-size.
