Description: Epoch TH Series (EPP-TH, CEP-TH, EPBT type) cutting tools with a newly developed TH coat has an excellent oxidation-resistant property and efficient chip flow (TH Power Mill). A new flute shape that is rigid and of good R accuracy as well as high tool rigidity and cutting edge strength (TH Hard) has been adopted (TH Hard Ball). Epoch Super Coating TH is a nano-composite coating material offering extraordinary heat resistance and hardness like oxidising temperature of 1100°C and layer hardness of Hv3600. Performance for high speed cutting and highly efficient machining of hardened steel ensure long life and high quality of hardened steel materials like 45-60 HRC, SKD 11, SKD 61, SKH, SUS 420 type steels and pre-hardened steels CENA1, NAK80. This is suitable for dry cutting since the generation of heat during cutting is low. The tool handles various materials from pre-harden steels (35HRC class) to hardened steels. This tool offers longer life than with the tool of conventional coating for high speed cutting. Advantages include power mill design with efficient chip flow (TH Power Mill), Direct milling of hardened die steel (TH Hard Ball), Tolerance of +/-0.005 mm (under dia.6) and highly accurate finish cutting (TH Hard Ball).
