| 摘要 |
The present invention relates to a rotatable drilling tool for chip removing machining that comprises a basic body (1) and an insert top (2) that is detachably connectable to the basic body (1). The basic body (1) is divided longitudinally into a coupling segment (10) and into a transportation segment (12) that is longer than the coupling segment (10). At least one chip flute (9) extends through the coupling segment (10) and the transportation segment (12) and has a smaller depth in the coupling segment (10) than in the transportation segment (12). |
