Cermet P10 Grade
Grade
General purpose cermet from finishing to roughing. Special technology improves the material's resistance to thermal shock, allowing safe use even for wet machining.
For stable machining of ductile cast iron we recommend this material, made by coating carbide H1 with alumina for increased wear resistance.

Grade
CW10HA This material exhibits excellent wear resistance when cutting high-hardness steel by combining a high-hardness carbide base material with a nanometer-level ultra-multilayer coating. This ultra-fine alloy steel offers exceptional toughness, excellent welding resistance at low to medium speeds, a sharp cutting edge, and stable performance for fine-diameter 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.

Cermet P10 Grade
Grade
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.
T R S 2.1 (GPa) Hardness 91.8 (HRA)
BNC500
By combining a ceramic coating with excellent heat resistance and a substrate with excellent wear resistance, stable long life can be achieved even when finishing difficult-to-cut cast iron materials.

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.
BN2000
A CBN material with an excellent balance of wear resistant and chipping resistant properties. Reliable performance is achieved in a wide range of cutting conditions in continuous and medium-heavy interrupted cutting.
AC520U
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.
BN500/BN7000
A CBN material with Co binder developed for cast iron. BN7000 is a material with excellent wear resistant and chipping resistant properties. BN7000 is recommended for high speed cutting of cast iron. If not satisfied with the wear resistance, use BN500.
H1
Fine Carbide K10 Grade
DA2200/DA1000
Grade
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.
Ultra-precise sintering of ultra-fine diamond particles drastically improves the material's chipping resistance. With strength comparable to that of carbide (K10 type), it achieves a stable long tool life in interrupted cutting of aluminum alloys. Furthermore, the material boasts great cutting edge efficiency and achieves a good finish surface.
