Abstract: Tool turret for NC automatic lathes comprising a turret body, in which a plurality of tool drive shafts arranged about a turret indexing axis are rotatably mounted, and comprising a main drive shaft coaxial to the turret indexing axis and in drive connection with the tool drive shafts via a miter gear arrangeed in the turret body, as well as a change-over gear for driving the tool drive shafts at different rotational speeds. In order to provide a space-saving and simple construction, the change-over gear is arranged in the turret body between the main drive shaft and the tool drive shaft and is designed as a gear adapted to be changed over only when at a standstill and having no idling state between the drive positions.
