The problem is that they have very little lead-in, and are very short
in respect of the diameter, so keeping them straight would be a bit of
a nightmare, unless you could get it into a big drill to keep the
thing aligned.

Useful for cleaning up manifold threads though, which is the main
reason we have them.
