Tool Material Type	Features
High-Speed Steel	Hardness and wear resistance are inferior in comparison to cemented carbide, but as it is high in toughness, it is resistant to abnormal damages such as chipping and fracture. Suitable for machining with large cuts.
Cobalt High-Speed Steel	Refers to high-speed steel materials to which cobalt is added, which can be expected to have improved wear resistance as compared with high-speed steel.
Powdered High-Speed Steel	Since powdered high-speed steel has fine particles, the degree of coupling is high, and the wear resistance is higher than cobalt high-speed steel. In addition, since the tool toughness is higher than cobalt high speed steel, it does not easily chip.
Carbide	Carbide end mill has higher high-temperature hardness properties compared to high speed steel and powdered high speed steel, with features such as "allowing high-speed cutting" and "long tool life". Also, since the tool rigidity is high, it is suitable for high-precision processing. However, since the toughness is inferior to high speed steel and powdered high speed steel, it easily chips or fracture.
Alloy High-Speed Steel	High-alloy dissolved high-speed steel with uniformly dispersed fine carbides to improve the high-speed performance as compared with high-speed steel.
