Features of Epoch Pencil Deep Ball Evolution Improved heat-resistant coating • The heat-resistant TH coating used previously has further evolved. A laminated structure is used to achieve both heat resistance and adhesion strength. • Achieves even higher hardness (3800HV) than before! Exhibits good abrasion resistance. (Hardness of conventional high-hardness membrane: 3600HV) • Offers long life and minimal performance variation when cutting high-hardness materials such as plastic molds, diecast molds, etc. • Increased heat resistance enables longer life for either wet cutting or dry cutting. Cross-section...

Tool shape for stable cutting. Reliable backdraft shape Inherits the reliable backdraft shape to enable chattering to be reduced when performing point cutting. Back draft effect Work material ■ Pre-hardened steels CllEcI Hardness ■ 40HRC) JP-LElíBc^ Surface roughness JP-LElíBc^ Surface roughness Adopt reliable compound neck shape •EPDBP-TH ■znmo&zRt.T-jKom.n Adopt compound shape of R used for EPDBP-TH and taper to achieve both breakage resistance and deflection suppression. Deflection, which is a problem when deep cutting, is reduced, enabling processing with low dimensional errors. Static load...
