Tooling by DIJET Indexable Tools QM MAX G II GMXTYPE Feature of product ”QM MAX G II” GMX / MXG type, indexable cutter with high efficient roughing. ● 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). ● Insert thickness: 4mm improved strength by 1.2 times compared with conventional tool. PH Breaker ● Economical double-side insert (4 corners). ● New strong edge type “PH breaker insert” Double-side usable! is excellent in fracture resistance and applicable to heavy cutting. Insert thickness: 4mm ● 2 insert grades “JC8118” & “JC7560” can be widely applied from general & mold steel to hardened die steel & high strength stainless steel. ● Application < JC7560> P M K H I SO P01 P10 P20 P30 P40 M01 M10 M20 M30 M40 K01 K10 K20 K30 H01 H10 H20 for high hardened for general & mold steel less than 50HRC steel less than NEW NEW NEW NEW JC8118 JC8118 JC8118 JC8118 Applicable & high strength 35HRC. range NEW JC7560 NEW JC7560 stainless steel.
