Indexable Tools Cutting resistance (N) Tooling by DIJET 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 strengthby 1.2 times compared with conventional tool. PHBreaker ● Economical double-side insert (4 corners). ● New strong edge type “PH breaker insert”is excellent in fracture resistance and Double-side usable! 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> ISO P M K HP01 P10P20P30P40M01M10M20M30M40K01 K10K20K30H01H10H20for high hardenedfor general & mold steel less than 50HRC steel less than NEW JC8118 NEW JC8118 NEW JC8118 NEW JC8118 & high strength 35HRC.
