Cubic boron nitride has high hardness, high thermal stability, the iron element is inert, so the most suitable for making the following material cutting tool:

All kinds of cutting hardened steel, including carbon tool steel, alloy tool steel, high-speed steel,bearing steel, die steel, etc.;

Cutting the iron-based, nickel, cobalt and other thermal spraying (welding) parts.

Higher hardness and other excellent properties of diamond tool with, making it, the application range is more extensive, processing all kinds of difficult machining materials, non processingmaterials;

For non-ferrous metals, mainly of copper, aluminum and its alloys, ultra precision machining; thediamond tool, especially natural diamond cutting tools, the cutting edge can be worn very sharp,grinding out radius of nanometer;
