摘要： The tool and the tool holder each have two sections (18, 19, 20, 21) with different cross-sectional sizes arranged axially one behind the other. These sections (18, 19, 20, 21) on the tool shaft (3) and in the tool holder (1, 2) form reciprocal bearing surfaces. The first section (18) on the tool shaft (3) and the first section (20) of the tool holder (1, 2) have rotationally driving and locking means (5, 11, 12, 13, 14, 15, 16) which are operatively connected in a reciprocal manner. A tool and a tool holder are provided which are very compact and wear-resistant. To this end, the rotationally driving and locking means (5, 11, 12, 13, 14, 15, 16) are arranged in parallel in the axial direction of the shaft (3) and/or the tool holder (1), and they are arranged in series relative to each other in the circumferential direction. In addition, the distance between the rotationally driving and locking means (5, 11, 12, 13, 14, 15, 16) in the first section (18, 20) of the shaft (3) and/or the tool holder (1) and the cross-sectional transition from the first section (18, 20) to the second section (19, 21) having the larger cross section is shorter than the region of the shaft (3) and/or the tool holder (1, 2) equipped with the rotationally driving and locking means (5, 11, 12, 13, 14, 15, 16).
