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.
