Tooling by DIJET QM MAX G II MXGTYPE Feature of product ”QM MAX G II” GMX / MXG type, indexable cutter with high efficient roughing. O Low cutting force inserts with optimum cutting Negative insert edge for high feed machining. * Compared with conventional positive type Optimum cutter, chips thickness of QM MAX G II reduces cutting edge by 14% (in case of ap=0.6mm). O Insert thickness: 4mm improved strength PH by 1.2 times compared with conventional tool. Breaker O Economical double-side insert (4 corners). O New strong edge type “PH breaker insert” Double-side usable! is excellent in fracture resistance and applicable to heavy cutting. Insert thickness: 4mm O 2 insert grades “JC8118” & “JC7560” can be widely applied from general & mold steel to hardened die steel & high strength stainless steel .
