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.

Advantages
1. Widely used for down-the-hole (DTH) drill bits.
2. With high impact resistance and excellent wear resistance.
3. Diamond DTH bits use different PDC insert sharps According to the different working conditions.
4. Stable footage efficiency improves work efficiency and benefits users.
5. The tungsten carbide DTH drill bit is easy to scrap because of the lack of wear resistance; the DTH drill bit features higher strength resistance and longer service life(10-15 times tungsten carbide insert) and reduces the cost of DTH bits.
6. Strict quality control before delivering.
