The cutting tools with PCBN complex can be used for rough and finish machining on the hard materials, such as gray cast iron (iron content ≤10%), alloy cast iron, chilled cast iron, high Cr cast iron, high Mn cast parts, hardened steels, alloy steel etc.

PCD complex is bonded by diamond and tungsten carbide substrate under high temperature and pressure. With the advantages of high hardness and great wear resistance, they are sutable for making drills, to drill soft and medium hard rocks, and machining of woods, non-ferrous metals and their alloy in the industries of petroleum, coal, geology, drilling and machining
