David,
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.
