    Abstract: 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.
