Tungsten carbide insert with high hardness and wear resistance,cutting performance much higher than HSS,durability is several times to several dozen times of high-speed it’s good cutting performance,tungsten carbide is widely used as cutting tool material .

During cutting machining, tool performance with decisive influence to cutting efficiency, precision, surface quality. Two important key index for tungsten carbide tool performance---hardness and strength always with conflict, high hardness material with low strength,while increase strength always as the cost of reduce order to solve this tungsten carbide material conflict,better improve cutting performance for tool’s,
Coating is an effective method,to improve cutting  efficiency , increase machining precision, prolong tool’s service life and reduce processing cost.

EJ Carbide insert coating types:
  1. CVD vapor deposition coating
Coating material is TiC,increase tungsten carbide tools’ service life with 1-3 times . thick coating,dull cutting edge,good to improve cutting speed and lifetime.
  1. PVD physical vapor deposition coating
Coating material is TiC,TiAIN and Ti(C,N),increase tungsten carbide tools’ service life with 2-10 times.thin coating, sharp cutting edge,good to reduce cutting force. maximum coating thickness ≤16μm .
