I am having trouble finding taps or thread mills to cut a 1/2-5 acme 2G thread. This thread is awful coarse for this size hole. Can you cut a 1/2-5 internal thread or is this impossible. Thanks for any help in advance.
I have to cut a 1/2-5 acme thread in 17-4ss. I am having trouble finding taps and thread mills for this thread because the pitch is so coarse for the size. Any suggestions would be greatly appreciated.
