Er... what is a broach drill pse?
A neat fitting sleeve with a protruding one side flat threaded hard tooth can be wound off and on to improve a thread, but unless have some suitable tube requires a lathe. Old ball race rings softened provide handy sleeves for a variety of uses..
Incidentally where a die is possessed the old style two piece dies are much superior for restoring threads as can be started on.
