摘要： The invention relates to a drilling tool with a base (32), having a central axis of rotation (24), and a drill bit (34), detachably connected to the base (32). The drill bit (34) has a coupling part (96), which can be coupled with a coupling receptacle (94) on the face of the base (32) and has at least two convexly curved centring portions (40), which are arranged such that they are distributed over the circumference and engage with an exact fit in complementary concavely curved centring portions (42) of the coupling receptacle (94). The coupling part (96) has a complementary driver stop (46), meshing with a rotary driver (44) of the coupling receptacle (94). It is claimed as novel that the centring portions (40, 42) of the coupling part (96) and/or of the coupling receptacle (94) have clamping surfaces (48, 50), which run onto each other in the manner of a rotary wedge until the driver stop (46) and the rotary driver (44) come up against each other counter to a predetermined direction of rotation.

摘要： The present invention relates to a tool for the machining of a tool, and also to a corresponding holder for this type of tool. In order to achieve improved cooling, a tool is proposed with a cutter insert (14a) with at least one cutter (22a, 23a, 24a) and with a holder (12a) with a cutter-insert receptacle (18a) arranged in the region of the workpiece-facing face side (16a) of the holder, in which the cutter insert (14a) has been arranged, where the arrangement has, in the holder (12a), a coolant bore (28a) which leads to at least one coolant outlet (44a), which has been arranged at the workpiece-facing face side (16a) of the holder (12a) laterally alongside the cutter-insert receptacle (18a) and has been designed in such a way that coolant is discharged in the direction of the cutter insert (14a).

摘要： The invention relates to a cutting insert (12), an associated tool holder (14) and a tool (10) having a cutting insert (12) of this type and a tool holder (14) of this type. The cutting insert (12) has a base body (20) that defines a cutting insert longitudinal axis (18), at least one cutting body (24) laterally projecting from the perimeter of the base body (20) and having a blade (25), and a cutting insert borehole (22) provided in the base body (20) and extends along the cutting insert longitudinal axis (18), wherein multiple elevations (40) are provided on an underside (38) of the base body (20) running transverse to the cutting insert longitudinal axis (18), said elevations being distributed in a peripheral direction and protruding from the underside (38) of the base body (20) in such a way that a respective relative depression (42) is produced between two respective neighbouring elevations (40), wherein the cutting insert (12) has at least one radial contact surface (48), multiple axial contact surfaces (52, 66) and multiple torque transfer surfaces (56, 56') for contacting the cutting insert (12) on the tool holder (14).
