Super Endmill For HRSA

HRSA, a material with higher strength at high temperature and corrosion resistance than general alloy, is commonly used for aerospace engine and parts of generator turbine.

HRSA is divided into Ni Based, Ni-Fe Based, and Co Based heat resistant super alloy by elements and Ni Based heat resistant super alloy such as Inconel718, Hastelloy, Waspaloy and etc. is most generally used.

HRSA is a representative of hard-to-cut materials causing short tool life due to work hardening, low thermal conductivity and high-temperature strength.

Low thermal conductivity makes increasing cutting speed impossible due to generating high temperature while machining at the edge.
Maintaining high strength at high temperature and work hardening also cause rapid wear, breakage, and severe damage on the edge of cutting tools.

KORLOY launches Super Endmill, the most effective tool for hard-to-cut material in HRSA machining.

Super Endmill increases machinability and stability in machining due to positive rake angle and irregular flute spacing shape.

In addition, Super Endmill ensures excellent tool life preventing fracture on cutting edge and increasing wear resistance in machining due to high toughness carbide substrate and new coating with high temperature hardness and oxidation resistance.
