High speed steel (HSS)
Advantages: Good toughness, suitable for low-speed and heavy-duty processing.
Limitations: Poor heat resistance and limited cutting speed.
hard metal
Advantages: High hardness, high wear resistance, suitable for high-speed machining.
Category:
K class (tungsten cobalt class): Good toughness, suitable for intermittent cutting.
P class (tungsten titanium cobalt class): high hardness, suitable for continuous cutting.
Coating technology
TiN: Gold coating enhances wear resistance.
TiCN: Silver gray coating, suitable for processing cast iron.
TiAlN: Purple coating, excellent high-temperature stability.
