GMM-MT
                 Specific chipbreaker for cut-off operations requiring sharp cutting performance.
GMM-NB           Minimizes the Boss.

                 Cutting edge is flat with no chipbreaker.
                 Good performance for brass, etc.

 GMM-TK          Stable design with chipbreaker for cut-off.                                                                                                                                                              H
 GMN-TK          Large corner-R.
GMN (Std.)       2-edge for economical performance.

                 Same chipbreaker geometry as GMM-TK.
                 1-edge.
                 Wide application range.

                 Mainly for deep grooving, but available for groove widening and turning due to projection near side cutting edge.
                 1-edge and wide application range. Available for cut-off applications.
