The tool holder (1) has connected at its rear part a mechanism (2) to produce vibration. In a cut-out (3) of the head of the tool holder is a tool (4) such as a drill which lies inclined to the axis of the tool holder. The drill is held by the upper edge (5) of a first clamp element (6) which is formed by a threaded cone on the front end of the tool holder. This first element has a second element (7) screwed to its rear end. The sleeve (7) clamps the element (6) against loosening whereby the clamp element (6) can not be separated from the drill and thus from connection with the vibrating tool holder (1). |
