Advantages of our tungsten carbide mining drill insert  

 

1,Using over 99.95% high purity tungsten carbide powder,the strenght and hardness will be more better.thereby a longer service life;

 

2,Taking isostatic pressing precision machine,our carbide button has a uniform density,and do not break easily;

 

3,Through the overvoltage sintering furnace for sintering, The wear resistance of carbide buttons will be increased by 24%;

 

4,Grinded by centreless grinder ,its has precise size, welding will be more tightly, and not to drop from drill.
