A gang tooling is disclosed for a lathe having a main spindle with an axis of rotation, a longitudinal carriage movable along a z-axis parallel to the spindle axis and a cross-slide carried by the longitudinal carriage and movable along a x-axis transverse to the spindle axis. The gang tooling comprises a longitudinal plate for removably securing to the cross-slide. The plate has a dovetail mortise and a wedge that cooperates with a dovetail tenon on the cross-slide for removably securing the plate to the cross-slide. The plate has a dovetail tenon for cooperating with a dovetail mortise in a plurality of tool holders for removably securing the tool holders to the plate. The plate can be removed from the cross-slide without disturbing and removing the tools installed on the plate, thereby permitting the tool holders to remain secured to the plate at their original relative positions.

A coolant supply system for a machine tool comprises a coolant source; a nozzle for directing coolant to inside of a workpiece from the coolant source; another nozzle for directing coolant to outside of the workpiece from the coolant source; and a valve for automatically selectively directing coolant only to the inside of the workpiece, thereby increasing coolant flow to the inside of the workpiece when needed.
