    • The invention relates to a cutting tool for a machine tool, comprising a cutting head (1), a shaft (2), and a coupling which removably fixes the cutting head (1) to the shaft (2), said coupling comprising a coupling pin (6) on the back of the cutting head (7) and a receptacle (5) in the shaft (2), which receptacle is complementary to the coupling pin (6) and accommodates the coupling pin (6) when the coupling is closed, comprising a central coolant channel (20) in the shaft (2), which separates into two sub-channels (12) in the region of the receptacle (5), the two sub-channels (12) flanking the receptacle (5) in the wall thereof and opening into the flat contact surface (10) annularly surrounding the opening edge (8) of the receptacle (5), and comprising a flat collar (16) on the back of the cutting head (7) having an annular distribution groove (15). The tool also comprises at least one coolant hole (19) connecting the cutting edges (14) on the cutting head (1) to the distribution groove (15).
    • 本发明涉及一种用于机床的切割工具,包括切割头(1),轴(2)和将切割头(1)可移除地固定到轴(2)的联接器,所述联接器包括联接器 在切割头(7)背面的销(6)和轴(2)中的插座(5),该接头与联接销(6)互补,并且当联接器 封闭的,包括在所述轴(2)中的中心冷却剂通道(20),其在所述容器(5)的区域中分成两个子通道(12),所述两个子通道(12)位于所述容器 ),并且开口进入围绕容器(5)的开口边缘(8)的环形的平坦接触表面(10),并且包括在切割头(7)的背面上的平坦的轴环(16),其具有 环形分配槽(15)。 该工具还包括将切割头(1)上的切割刃(14)连接到分配槽(15)的至少一个冷却剂孔(19)。
