T2500A T2000Z General purpose cermet from finishing to roughing. Special technology improves the material's resistance to thermal shock, allowing safe use even for wet machining. Cermet is coated with newly developed PVD film for smooth surface and good adhesion. The material easily doubles tool life compared to non-coated cermet, and enables a high-quality finished surface. T2500F Cermet with fine and uniform grain structure, achieving improved toughness and high hardness. Excellent thermal shock resistance helps enable stable finishing. Cermet insert is coated with smooth PVD film. This material has superior welding and chipping resistance compared to non-coated inserts. T130A The unique production process of this tough cermet achieves a fine and uniform structure that has excellent chipping resistance. Achieves longer tool life than T1500A when used for interrupted cutting finishing. AC520U H1 The tough substrate is coated with multiple layers of nanometer-level thickness to create a material suitable for cutting difficult materials such as titanium with excellent wear resistance and notch wear resistance. With slightly higher wear resistance than K10 material, this material is a best selling type of carbide that can be used across a wide range from roughing to finishing. The cermet is treated further with a layer of ceramic kept uniform with the new PVD method This doubles the tool life while maintaining the toughness of the material. T130ZX
CW20PA Suppressing abnormal damage through a smoother surface, this grade provides highly stable tool life in diverse conditions. AC820P The main grade for steel. The newly developed CVD method allows for a dense yet smooth coating that achieves outstanding versatility and consistency. Even among ultra-fine particle alloy steels, this material is notably tough; it also boasts excellent welding resistance at low to medium speeds, has a sharp cutting edge, and handles chatter suitably for fine diameter machining.

CW15KA
This cast iron grade has excellent wear resistance in high-speed cutting due to its high-adhesion, high-strength coating.
AC410K
The hardest material for cast iron. Use if not satisfied with the wear resistance of AC700G. Note that this type is not suitable for heavy duty interrupted cutting.
AC700G
Fine Carbide K10 Grade
Grade
Heat resistant carbide alloy is coated with multiple layers of mainly tough alumina, with additional surface smoothing treatment, to produce a highly reliable material for machining cast iron.
