      GROOVE-TURN  JETCUT Tools High-Pressure (up to 340 bar)   General Information





              The high-pressure coolant feature has been in existence
              for a long time in the metal removal world, taking a bigger

              role in today’s machining. ISCAR was one of the first
              cutting tools companies to respond to market needs by
                                                                improvement in tool life. Usually will not have an effect on
