<p>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).</p> |
