Product Description

Product Description

Tungsten Carbide buttons have their unique working properties and are therefore widely used in:

1. Oil drilling and shoveling, snow plow machines and other equipment.

2. Used for coal drilling tools, mining machinery tools and road maintenance tools.

3. used in quarrying, mining, tunneling, and civil construction.

4. DTH Drill bit, thread drill bit and other drill bits
 

Advantage

1) Made of special and excellent raw material, have more stable properties, increase the yield of complete drilling and mining bit substantially;

2) Extra grain size available, have higher impact resistance and lower hot crack and breakage;

3) Ground and tumbled, ensuring uniform of dimension and surface smoothness, easier to mount;

4) HIP sintered, increase the strength substantially therefore extend service time;

Full range of types and specifications available.
