HITACHI TOOL
Epoch Thread Mill Series
ET-(U)-PN
Enables stable thread-cutting of hardened materials with hardnesses of 45HRC or higher.
・Tough and strong edge design provides stable threading of high-hardness materials.
・Tip shape that reduces cutting resistance suppresses tool bending.
・Drastically reduces tool breakage, a particular problem when threading high-hardness materials.
Epoch D Thread Mill (D:Direct)
EDT-(U)-TH
Enables a single tool to cut the pilot hole and threads at the same time in hardened materials with hardnesses of 45HRC or higher.
・This single tool can perform both pilot hole drilling and threading simultaneously.
・High-strength edge shape design suppresses edge tip breakage in severe machining environments on high-hardness materials.
New TH coating further improves the hardness and oxidation resistance of the previous TH coating.
・Hardness and oxidation resistance of TH coatings is further improved. Enables longer life and higher efficient when cutting high-hardness materials. Hardness: 3800HV; Oxidation temperature: 1200℃
(Si nano composite coating with finer crystal particles)
・Exhibits amazing performance in ultra high-efficiency machining.
