Tooling by DIJET Indexable Tools TDM EXTREME EXTDMTyPE Indexable radius cutter for hard-to-cut material. ▼ ▼ E° Irregular pitch prevents ▼ chattering & vibration ▼ A° (except for 3 tooth type). D° ▼ ▼ ▼ ▼ B° C° ▼ ▼ Achieved edge sharpness & strength by helical cutting edge Through coolant hole: surely coolant supply to cutting edge Adopted GN surface-hardening treatment on thermal resistant high strength steel gives high hardness over 65HRC and secure insert pocket and holder against thermal deformation, improved body durability and tool life by 30% or more. Make it difficult to be damaged even under severe cutting conditions. Also rust-proof and anti-welding effect is much improved.
