Presumably this is possible only with a QCTP without removing the toolbit
from the holder? If you took it out of a lantern or a rocker you will never
be able to re-insert it in exactly the same way. Or am I missing something?

Grinding or honing the bit moves the edge away from the cut. You would
have to reset it if you were making multiple parts but not when
sneaking up on the finish dimension of the first or only one, after
roughing them all.
