摘要： The invention relates to a rotary tool (2) designed in particular as a modular drill and extending in an axial direction (4) along an axis of rotation (6). The rotary tool comprises two coupling parts, namely a carrier (10) and a cutting head (12) that is exchangeably attached to the carrier (10). A pin receiving means (20) is provided on the carrier (10), into which pin receiving means a coupling pin (40) of the cutting head (12) is introduced in a clamping and reversible exchangeable manner. The pin receiving means (20) and the coupling pin (40) have clamping sections (32a, b) and torque sections (30a, b) that correspond to one another. In order to permit simple production, these clamping and torque sections are oriented parallel to the axis of rotation (6). In addition, in order to prevent pulling-out in an axial direction, stop surfaces (38a, b) are provided on the pin receiving means (20) and on the coupling pin (40), said stop surfaces being effective in an axial direction (4) and corresponding to one another. These stop surfaces are preferably horizontal and therefore perpendicular to the axis of rotation (6).

摘要： A coated cutting insert for removing material from a workpiece that includes a substrate is disclosed. A wear-resistant coating on the substrate that includes an α-alumina layer and a Zr— or Hf— carbonitride outer layer deposited on the α-alumina layer. The Zr— or Hf— carbonitride outer layer is subjected to a post-coat wet blasting treatment. The wet blasting changes the stress condition of the exposed alumina coating layer from an initial tensile stress condition to a compressive stress condition.
