Would this work for you? https://www.shars.com/1-x-8-rh-threading-bar This one takes a standard triangular insert.
4 TIP is pretty course so the standard G60 (8-14 TPI) won't work.

No, there is no thread spec given. Hard to tell from the pictures just how deep it will cut.
You may have to do it like we did in the dinosaur era, make a boring bar and grind up a HSS tool bit.
