| A machine tool having a turning function and a milling function includes a spindle, a spindle housing supporting the spindle in a rotatable manner, a main clamp provided at the spindle, an auxiliary clamp provided at the spindle housing, and a double arm with a first gripper and a second gripper. The auxiliary clamp clamps a tool holder together with the main clamp during fixing a fixed tool. The double arm exchanges a tool holder grasped at the first gripper for another tool holder grasped at the second gripper by rotating and sliding movements. The auxiliary clamp is arranged at a position not interfering with the double arm that moves during exchanging tool holders. By such a configuration, a machine tool achieving a clamping force sufficient to withstand the load during a turning process, and that allows tool exchange in a short period of time, and a tool holder employed in such a machine tool, can be provided. | ||||||

| A cutting tool, in particular for the turning out of drillings, has a clamping piece (10) for fixing the tool in a clamp holder. The clamping piece (10) includes two clamping surfaces (30), which converge on each other in the direction of the one side (32) of the clamping piece (10). In the direction of the other side (34) of the clamping piece (10), the clamping surfaces extend into a roof-type surface (36). On the side of the clamping piece (10) facing away from the clamp holder, the clamping surfaces connect to a rod-like neck piece (12), which tapers in cross-section relative to the clamping piece (10). The free end of the clamping piece is connected to a cutting piece (14) as one piece, and is provided with a cutting edge (16) on the external end thereof to which a face (18) of the cutting piece (14) connects in the direction of the neck piece (12). A high degree of reinforcement for the neck piece and the cutting piece arranged on its free end with its blade or the blade edge is achieved. The neck piece (12) has two reinforcement pieces running along it, transverse to the plane of the cutting edge (16). The reinforcement pieces are reinforcing ribs (20, 22) which convergently taper in the direction of the cutting piece (14), are diametrically opposed in relation to the neck piece (12) and have their greatest width at the point of transition into the clamping piece (10). | ||||||

| A rotatable chuck for clamping a shank portion of a rotatably operating machining tool includes a rotatable chuck body provided with a cylindrical bore concentric with a rotation axis of the chuck body. The circumferential surfaces of a clamping portion of the bore are arranged to apply a clamping force around the circumference of the shank portion of the tool when it is mounted in the chuck to fixate the tool in the chuck. The chuck is provided with auxiliary pull out preventing means for preventing inadvertent pull out of the tool in the axial direction of the bore during machining operation, as well as auxiliary rotary preventing means for preventing inadvertent rotation in at least one direction in relation to the chuck during machining operation. The auxiliary pull out and rotary preventing means include an attachment member positionable in an inner portion of the bore and attachable to the shank portion to be clamped, such that the tool and the attachment member will be prevented from being pulled apart in the axial direction and from being rotated in at least one direction in relation to each other. | ||||||
