    • A cutting tool, comprising a body which has a seat for a cutting insert (5) in a forward part and a channel (8') for the feeding of a coolant to at nozzle (12) in a rear part, the channel comprises a through bore (15) with orifices for inflow and outflow and which is mounted in a forward part (10) which is exposed towards a cutting insert seat so that a jet (33) of fluid is directed towards the area of the seat, said channel (8') opens out into a cavity (9) behind said front part (10) which communicates with the bore of the nozzle. The nozzle comprises a nozzle insert (14) with a rotationally symmetrical shaped enveloping surface which can be rotated round its own centre axis between different angularly rotational positions in relation to a similar rotationnally symmetrically shaped hole (20) in the front part (10) and fixable in one of these positions so that a jet of fluid (33) from the nozzle body which is eccentrically positioned in relation to the centre axis of the nozzle insert can be set up, as required, to impinge on different points of impact (T, T1).
    • 一种切削工具,包括:主体,其具有用于前部的切削刀片(5)的座和用于将冷却剂供给到后部的喷嘴(12)的通道(8'),所述通道包括 通孔(15)具有用于流入和流出的孔口,并且安装在朝向切削刀片座暴露的前部(10)中,使得流体的射流(33)被引向座椅的区域,所述通道 (8')打开到与喷嘴的孔连通的前部(10)后面的空腔(9)中。 所述喷嘴包括具有旋转对称形状的包封表面的喷嘴插件(14),所述喷嘴插件(14)可相对于所述前部(10)中的类似的旋转对称形状的孔(20)在不同的角度旋转位置之间围绕其自身的中心轴线旋转, 可固定在这些位置中的一个位置,使得可以根据需要将来自喷嘴体的相对于喷嘴插入件的中心轴线偏心定位的流体喷射流(33)设置成撞击不同的冲击点(T ,T1)。
