Deep thread milling ?

Deep (50.8mm) threading M36-4. What's your first choice to do the job. Can't be turned. Can be milled.
I have some tiny little micro boring bars I use for deep thread milling
small threads, but a 4mm pitch needs a huge tooth... and of course the reach to do the job.
Not my project. Operator would prefer some form of thread milling. The work piece was not described.

Nope. They machined a boring bar and brazed a threading insert onto it. The job was done hours ago. Home made thread mill.
