<p>A cutting tool (2) includes a front part (5), which has a cutting insert (6), as well as a rear part (7), which is detachably mountable in a holder (3) in an appurtenant machine. The tool (2) comprises a plurality of nozzles (13), which have the purpose of spraying jets (4) of high pressure cooling liquid towards the cutting insert (6). Supply of cooling liquid to these nozzles is guaranteed via a duct system positioned inside the tool, which system includes an equally large number of mutually spaced-apart ducts as the number of nozzles, the nozzles being adjusted in order to direct the jets thereof towards different points of impact on one and the same cutting insert. In this connection, it is possible to close the individual ducts inside the tool individually in order to enable spraying of only one jet at a time towards the appurtenant point of impact on the cutting insert.</p> |
