1. High cubic content gradient carbide substrate, gives good anti-deformation resistance and excellent high temperature performance. MT-TiCN+AlO3+ TiN coating has very good surface quality, and easy to recognize wear. Suitable for semifinishing to finishing steel machining.
2. Relatively High cubic gradient carbide substrate, with good anti-deformation resistance and toughness. MT-TiCN+Al2O3+-TiN coating has very good surface quality, and easy to recognize wear. Suitable for semifinishing to roughing steel machining.
3. Low Cobalt content, and high cubic content carbide substrate combine with thick TiCN and Al2O3, treated by special after coating treatment, which gives insert wonderful wearing resistance. Preferred grade for semifinishing to finishing steel machining.
