GRADE	COATING	COLOR	WORKING MATERIAL	APPLICATION
SP8025	CVD (MT-TiCN+Al2O3+TiN)	golden yellow	P10-P30	The carbide substrate have good anti-deformation resistance and toughness. MT-TiCN+Al2O3+TiN coating has very good surface quality and help to recognize wear easily. It is suitable for semi-finishing and finishing steel machining.
SP8125	CVD (Multi-TiCN+Al2O3)	black	P10-P40	The carbide substrate have mild cobalt content and high cubic content, combining with thick TiCN and Al2O3, treated by sepcial technology after coating treatment, which gives inserts strong wearing resistance. It is prority for semi-finishing to finishing steel machining.
SM8020	PVD (Silicon+TiAlN)	purple	M10-M30	Micro WC grain substrate with high Co maintain cutting edge strength and it has smallest coefficient of friction and good nano hardness with good thermal stability silicon coating. The grade is very good for interrupt turning and milling for stainless steel.
SK8010	CVD (thick TiCN+ textured Al2O3)	black	K10-K30	The medium-coarse substrate combine with thick TiCN and textured Al2O3, after special coating treatment, it has strong wear-resistance. The grade is suitable for high-speed semi-finishing cast iron turning under stable working condition.
