Abstract: The invention relates to a device for a wireless power transfer system for a vehicle. The device comprises a coil formed by at least a first conductor wire forming a first sub coil with a plurality of windings and a second conductor wire forming a second sub coil with a plurality of windings. The coil has a first loop and a second loop positioned next to each other. The first and second loop have a central portion of the coil in common where said at least first and second conductor wires extend from the first loop to the second loop and vice versa. The first and second conductor wires are arranged next to each other in the central portion. The first and second conductor wires are arranged above each other in an outer portion of the first loop and in an outer portion of the second loop.

Abstract: A cutting insert for a rotary drill tool and drill tool assembly in which an insert and a support body are coupled axially via a complementary shaped projection extending radially outward from the insert and received with a recess indented at a radially inward facing surface of the support body.

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.
