ABSTRACT:
In a thread milling cutter comprising at its tip cutting edges for making a bore, said cutting edges are formed as face milling cutting edges which enclose a mutual angle of 180.degree. or more, so that the thread milling cutter on reaching the intended drill hole depth and in order to be laterally moved need not first be raised. Also, it is possible with the thread milling cutter according to the invention when using said cutter to make threads of any desired diameter with the same thread pitch because the tool tip does not run against the drill hole bottom when laterally moved or offset as with the known thread milling cutter.
In addition it is possible with the same tool to provide the thread at the entry with an edge-chamfer in such a manner that impairment thereof by formation of burrs is impossible.
