                           CBN GROOVING SERIES
                                                  (GY/MG)

                             FEATURES

                           aA combination with a high rigidity holder ensures high accuracy
                             and long tool life.

                              Holder rigidity is essential when grooving hardened steel. The GY series TriForce system
                              offers high rigidity equivalent to a solid type tool. MG has a wide insert location face for high
                              gripping force. The insert and holder combination allows delivery of excellent performance
                              when grooving hardened steel.

                              MG for narrow grooves and GY for general grooves are both available to allow selection of
                              the most suitable tool.
