<p>Rotating tool comprises a receiver part having at least two coupling pairs separated from each other and eccentrically arranged in relation to the central axis (8). Each coupling pair is formed by interacting coupling elements, namely a receiving pocket and a driver pin (18), which are structured so that they are flush to each other when the receiver part and the borer head (4) are joined together. The coupling elements have an asymmetrical cross-sectional surface and spread with increasing distance to the central axis. Preferred Features: The driver pin is formed as a prism. The coupling elements have radial outer-lying support surfaces and further receiving surfaces.</p> |
