MAIN COMPONENT AND APPLICATION

P series for steel cutting, K series for cast iron cutting and M series for general cutting.

ISO	Main Component	Characteristics	Application
P	WC-TiC-TaC-Co	Heat / deformation resistance.	Carbon steel, alloy steel, and stainless steel
M	WC-TiC-TaC-Co	Used for general cutting due to balanced heat resistance and rigidity.	Carbon steel, alloy steel, stainless steel, and cast iron
K	WC-Co	High rigidity and wear resistance.	Cast iron, non-ferrous metals, and non-metal
