Abstract: A method of determining pull-out of a cutting tool mounted in a rotatable tool holder includes the steps of rotating the tool holder and thus the cutting tool, machining a work piece with the rotating cutting tool, measuring an axial position of the cutting tool in the tool holder during machining by a position sensor in the tool holder, calculating an axial displacement from an initial position of the cutting tool by the measured axial position, and determining pull-out of the cutting tool when the axial displacement exceeds a threshold value. A rotatable tool holder for a cutting tool, a machine tool system including a rotatable tool holder and use of the tool holder and machine tool system is also provided.
