Thread milling is a versatile process used to thread a huge variety of hole sizes, particularly larger diameter holes. It has some similarities to tapping but differs from tapping in that the tool is meaningfully smaller than the hole to be threaded. Thus the tool moves in a circular path around the circumference of the hole to cut the thread.
