Rocket, depends on which variety they come in many different

taps and dies which actually make threads from scratch.
on a lathe: "Gewindestrehler" ( no idea about the enlish tag for those.)
Google translates it as "thread chaser", which is this sort of device:

(not a specific recommendation).
That's a hand tool, though I suppose one could use it on a lathe too.
When the end of the bolt is really messed up, a device like this or a
thread file can work better than a die, since a die is apt to start
off wrong and cut a new thread in a different position than the old
one.
