I have a straight toolholder that takes a T P G 322 insert. I would
like to know if I can find an insert like this that would have a small
enough edge radius to be used for threading.


Tip radius for TPG322 is 1/32", for TPG321 it's 1/64". According to my
homemade hand grinding chart 0.016" is about right for 8 - 12TPI. You
could try it on finer threads and drill out the female thread a little
if it doesn't fit well.
