A vertical tool head for the headstock of a horizontal drilling-milling machine which is carried by a support means above and displaceable parallel to a horizontal tool spindle and can be clamped in its work position at a headstock projection and drivable by the horizontal tool spindle which is mounted in the headstock projection having a headstock clamping surface. The vertical tool head and the support arm can be selectively positioned, by means of two defined thrust movements of different length and opposite to one another in conjunction with a pivotable movement of the vertical tool head through 180 DEG about an axis arranged above and parallel to the horizontal tool spindle, in a park position and work position. In these positions a tool chuck device located at the end of a vertical tool spindle of the vertical tool head is disposed in front of the support arm. The vertical tool head, in the park position, is located above the headstock projection and has its front face located in a vertical plane containing the headstock clamping surface. |
