          Tool for External Threading


                          DCONMS




           WF
                 LF

          LU          — Usable length
          DCONMS — Connection diameter of machine side

          WF          — Functional width
          LF          — Functional length



          Main Advantages
       •  Reduces cutting time
       •  Provides longer tool life of cutting edge

       •  Very effective cooling down of the cutting edge,
          reducing sensitivity to heat fluctuations

       •  Enables better chip evacuation
