I'll try and get the CBN insert I have into the mail to you tomorrow, along with a very hard carbide one. Threading tool I recommend for your lay-down holder (I think you have one) would be an Iscar 16ER-AG60 grade IC907, or a Kennametal 16ER-AG60 grade KC5010. Those are both very hard grades suitable for you application. If on the off chance I have one of them in my collection, I'll send it to you.

I have some Valenite CNGA 432 T00820 Q6 (not sure what the Q6 means) inserts that I tried on the extra 12 MM rail that I have, I had to take shallow cuts but it turned ok, so I'm ok on inserts to turn the ends down with, I will look for a threading insert with the info that you have provided.
