H Endmill 


High hardened & heat treated steels (HRC 45~70) used in parts for automobiles and molds offer excellent durability and effective wear resistance. This hardened steel material apparently causes massive tool wear on relief surface involving high temperatures in high speed and dry machining. Additionally, large impact during machining results in chipping and tool breakage.


The H Endmill is specifically designed for machining high hardened & heat treated workpieces, complemented with an ultra fine substrate and a newly invented AlTiSiN coating layer. It features good adhesion on coating layer and excellent resistance to wear at high temperatures. As a result it improves tool life by delaying coating flaking at high speed and dry cutting conditions.
Thanks to the negative rake angle, blade design for low cutting load and special edge treatment, chipping resistance has significantly been improved to enable stable machining without edge breakage.


The H Endmill boosts tool life by more than 20% compared to previous products, delivering higher wear resistance and optimum tool geometries that suit machining high hardened & heat treated materials.
