The invention relates to a tool revolver comprising a revolver head ( 12 ) which is supported by a housing ( 20 ) and which can be rotated in relation to said housing ( 20 ) by means of at least one axial bearing ( 24 ). The axial bearing ( 24 ) is mounted in between the revolver head ( 12 ) and the housing ( 20 ) in the direction of the revolver head ( 12 ) by means of a locking member ( 32 ). The hydraulic medium producing the fluidic pressure can be placed in between the locking member ( 32 ) and a connecting element ( 38 ). The connecting element ( 38 ) engages with the locking member ( 32 ) from below in such a way that the axial bearing ( 24 ) is subject to pressure when the revolver head ( 12 ) is in a locked or unlocked state. Consequently, all major functions are brought together in a minimum amount of construction space, requiring only a minimum amount of components. The influence of the cutting force on the revolver head which can otherwise have a negative effect on machining accuracy, especially when rear side machining occurs, is thereby avoided.
