          Insert Positioning

              The Twisted Insert for Cut-Off                    Setup
              and Grooving Applications                       •  The optimal cutting edge height above the center of
              Machining depths longer than insert length is made   TANG-GRIP tools is up to 0.08 mm + 0.025 mm
                                                                W.O.C., an advantage when cutting solid bar to center
              possible with the double-ended, twisted insert body.  •  Cut-off as close to chuck as possible
              The rear edge is slanted in relation to the frontal   •  On new applications, first machine in the low or
              edge so it does not come into contact with        middle range of recommended speeds and feeds
              the machined groove surface when the tool
              penetrates deeply into the workpiece.             Machining
                                                              •  Consistency of speed and feed improves performance
                                                              •  Apply coolant abundantly
                                                              •  Secure inserts into clean pockets
                                                              •  Cutting forces on soft workpiece materials may
                                                                be insufficient to push insert well into pocket.
                                                                Tap insert into place using a plastic hammer
                                                              •  On a conventional lathe, lock the carriage
                                                                to prevent axial motion during cut-off


                                                                 (0.08+0.025) max.

              Clamping
              Extended, prismatic surfaces guarantee reliable, foolproof   Center Height
              clamping even in unstable machining conditions.

                   Screw-Clamping        Self-Clamping          Usage
                                                              •  Replace worn inserts promptly, the price of a
                                                                new one is much less than the risk of damage
                                                                from continuing with one that is worn out
                                                              •  Replace blades that have worn or damaged pockets
                                                              •  Never try to repair damaged pockets
                                                              •  Chip curling is dependent on the chipformer
                                                                type and the machining conditions

              Small diameters (D.O.C.)   Large diameters (D.O.C.)   •  Eliminates friction with groove walls,
              with screw-clamped Inserts  with self-clamped Inserts  prevents chip jam overload
                                                              •  Permits higher feeds
