The die tool () comprises a die having a flank () arranged concentrically with respect to the rotational axis (). The flank () has a front end surface () perpendicular to the rotational axis (). The flank () is conically shaped at least in the lower transition region () to the front end surface () and has a flank angle (W, W, W) smaller than or equal to 10 degrees, preferably smaller than or equal to 5 degrees.
