Turret indexing means allows indexing of one of the turret heads while a tool receiver fixed on the other turret head assumes in a predetermined cutting area relaive to the axis of the spindle. The saddle has a chip dropping wall formed between a guide bush and the pair of turret heads, with a front portion of the chip dropping wall downwardly slanting toward the front side of the lathe.
