Used to, but alas not any more,
but ask any toolmaker if they work to tenths of a thou!!

There are over 100 certified Tool and Die Makers where I work and none of
them work to .0001. We do precision grinding with 1/4" die grinders, disc
grinders, polishing stones and sand paper.

You're right, of course. Sometimes the last .0001" *does* matter. As far as
function is concerned, I'd be surprised if five people reading this group
were actually capable, or had access to facilities capable, of doing that
type of work.
