More tooling without carbide

My original idea with these inserted holders was to be able to use the same ground piece of HSS for internal and external cutting of threads. I have holders that I can do that with but I have also wondered how to make the sharpening easier for V threads.

In a previous post I showed the external tool holders. In this clip I show some internal holders for cutting threads, but as part of that, have to broach a hole on an angle through what ends up being a round section boring bar.
