    Abstract: Threading apparatus for a vertical milling machine includes a threaded sleeve at the upper portion of a milling machine draw bar and a split nut thread guide secured to the top of the milling machine and about the upper portion of the draw bar. When the split nut engages the threads on the draw bar, rotation of the draw bar causes the draw bar to move vertically in response to the mating threads of the sleeve and the split nut so that a thread cutting tool on the opposite end of the draw bar will cut threads in a work piece. By changing sleeves and split nuts, virtually any pitch thread may be cut.
