| 摘要 |
The invention relates to a rotative cutting device, in particular a drill, comprising a tool head (1) consisting of a hard cutting material and a tool shaft (2), which clamps the tool head (1) between two clamp extensions (13, 14) that project axially from said tool shaft (2), in such a way that the tool head is interchangeable. In the fixed position, the interconnected clamping surfaces of the tool head (1) and the clamping extensions (13, 14) of the tool shaft (2) lie on the surface of a truncated cone-shaped fixing peg (7), running coaxially with the longitudinal axis (6) of the tool shaft (2). Said fixing peg tapers in the insertion direction (17), facing the chuck end (12) of the tool shaft (2). |
