ABSTRACT:
A rotating head or the like having a drilling spindle and a tool carrier with an arrangement to finely adjust the tool carrier in a direction transverse to the axis of rotation of the spindle characterized by a wedge carrier which is mounted on the spindle for movement along the axis of rotation and has a bevel engaging a sliding surface of the tool carrier to shift the carrier transverse to the axis of rotation in response to movement of the wedge carrier and an arrangement for maintaining contact between the sliding surface and the bevel of the tool carrier preferably including the center of gravity of the tool carrier being offset relative to the axis of rotation on a side opposite the sliding surface so that centrifugal forces occurring during rotation of the rotating head press the sliding surface against the bevel.
