An automatic tool turret for a lathe including a base adapted to be detachably secured to the lathe way. A tool carrying head is mounted on the base for movement between a clutched work performing position and unclutched head rotating position. The movement is hydraulically accomplished so that the head is supported by a hydrostatic bearing created by the hydraulic fluid. The fluid pressures generated during the movement of the head between its clutched and unclutched positions is used to initiate a work performing operation and to initiate turning of the head.
