CEMENTED CARBIDE

K Series Grade (WC-Co) P,M Series Grade (WC-TiC-TaC-Co) Available grade series are HTi grades for cast iron, non ferrous metal and nonmetal, and UTi grades for steel and cast iron.

SELECTION STANDARD

MILLING

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	Workpiece
P	WC-TiC-TaC-Co	Heat / Deformation resistance.	Carbon steel, Alloy steel, and Stainless steel
M	WC-TiC-TaC-Co	Highly 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
