JST90

Regular and complete shape of cubo-octahedron with very high impact strength and high TI and TTI value. Applied to making cutting tools for hard stone and concrete, and also applicable for making electroplated tools or dressing tools like engineering driller or geological driller.

JST80

Shape is complete and regular cubo-octahedron with high purity, very high strength, toughness, thermal stability and very high impact resistance; Applied to making tools for sawing hard stone, such as wire saw, stripe saw, gang saw, large saw blade etc. For all kinds of concrete, geological drilling, engineering drilling, and all varieties of diamond dressing tools application as well.

JST70

Shape is complete with high purity, high toughness, thermal stability and high impact resistance. Applied to manufacturing tools for sawing hard stones as well cutting for concrete, engineering drill bit, and diamond dressing tools.

JST60

Shape is complete with high purity, mid-toughness, medium thermal stability and high impact resistance. Suitable for cutting moderate hard granite and marble, cutting / drilling non-reinforced concrete and diamond dressing products.

JST50

Shape is complete with high purity, mid-toughness, medium thermal stability and high impact resistance. Suitable for cutting mid-hard granite and marble, cutting/drilling non-reinforced concrete and diamond dressing products.

JST40

Shape is regular with wider strength scope. Applied to processing marble and other soft stone, cutting and drilling non-reinforced concrete and diamond dressing products.

JST30

Shape is regular with lower strength. For cutting and polishing soft stones like marble, and also suitable for diamond dressing tools.

JSTT Coated Diamond

Titanium coated JST diamond series, suitable for metal bonding system or vitrified bonding system. The coating greatly enhances the mechanical attachment of diamond to the bond matrix through the strong metallurgical adhesion between Titanium and the matrix. The coating also protect s diamond from oxidation or metal erosion which causes graphitization of the diamond, therefore, improves the application features of the diamond tools.
