This paper presents the results from an experimental study about high speed turning of stainless steel with the primary focus on the influence of changing shape of tool inserts upon the tool life. In the experiments of the present study, stainless steel SUS304 was turned under jet coolant conditions with three different shapes of inserts at a cutting speed of 300 m/min. The tool life was not as much extended as was expected when the shape of tool flank was changed under pressure 0.3 MPa. The results indicate that the size of film boiling area is the chief factor on the tool life in this case, and changing shape of the flank face will not lead to an reduction in film boiling area.
