If you are talking about what I think you are talking about, it doesn't seem very practical.? That's a pretty small size for that sort of thing.? Thread milling is a close cousin to single point threading and requires the same lathe capability to feed at a thread rate as the part rotates.? The only difference is that you have a powered rotating milling cutter independently powered and twirling about as you make just a single pass to create the thread instead of a threading tool and multiple passes.? I would think that for a 6 mm thread it would be extremely difficult to pull off.? Maybe I'm missing something here.
I used to handle a lot of repetitive tapping using a "fast tapper" or "tapping head" (Tapmatic brand in my case) which is a device with a clutch that automatically reverses once the tapping is done and you start withdrawing.? Might be worth looking into.

I have a requirement for some M6 internally threaded through holes. In the past I have done this same job by drilling holes and tapping with a standard tap followed by a bottoming tap.I usually produce about 80 pieces. As you can see this is a tedious and monotonous task. This time I am seriously considering doing this job by internal thread milling on the lathe. I am wondering if anyone on this group has ever contemplated doing the same? I have the means of grinding a carbide milling cutter so that will not be an issue. The parts are about 6mm through.
