PDC inserts are made of tungsten carbide substrates and diamond powder sintered under high temperature and high pressure, which have the impact property of tungsten carbide and the wear resistance of diamond. At the same time, due to the excellent thermal conductivity and wear resistance of diamond, the thermal fatigue failure in the process of rock breaking can be greatly reduced in the application process.

Note: The above specifications are for users to choose from. At the same time, different specifications of products can be produced and processed according to the requirements and drawing of users.
Advantage
1. HTHP press and have spherical/parabolic/conical/flat shapes.
2. With high impact resistance and excellent wear resistance.
3. The wear resistance and strength are improved greatly because of the special design of the diamond layer.
4. Optimizing the stress between the diamond layer and tungsten carbide substrate by the double layer. The diamond design greatly improves impact resistance and service life.
5. Stable footage efficiency improves work efficiency and benefits users.
6. Strict quality control before delivering.
Application
Widely used for oil/gas PDC drill bits, hole openers, stabilizers, and reamers tools.
