摘要： A method for releasing a screw connection between a core drilling device and a drill bit, wherein the screw connection is released by application of torque spikes to the drive shaft of the core drilling device, these torque spikes coming into effect when the drive shaft is driven counter to the actual drilling direction of the core drilling device. A core drilling device with which the proposed method can be carried out is also provided. To this end, the core drilling device includes a drive shaft to which torque spikes can be applied, wherein the drive shaft can be driven in a drilling direction and a second direction of rotation which is opposite to the drilling direction. A core drilling device, in which the reversal of a direction of rotation of a drive shaft of the core drilling device and application of torque spikes to the drive shaft are combined with one another such that, as a result of the combination of the reversal of the direction of rotation and torque spikes, a screw connection between the core drilling device and a drill bit can be released.

摘要： A rotatable cutting tool, which extends along a tool axis defining an axial direction, includes a cutting formation in a first axial longitudinal end region, which is configured for material ablation on a workpiece, and includes a screw-connection formation in a second axial longitudinal end region opposing the first, which is configured for screw connection with a coupling unit. The cutting tool includes key-contact surface formations diametrically opposing each other with respect to the tool axis, which are configured for torque-transmitting abutting engagement with key surfaces of a key. Each of the key-contact-surface formations includes at least two key-contact surface regions provided with spacing from each other in the circumferential direction about the tool axis, which key-contact surface regions are inclined away from each other such that they form a vertex projecting away from the tool axis.
