Product Introduction

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. At the same time, different specifications of products can be produced and processed according to the requirements and drawing of users.

Advantages

1. Widely used for down-the-hole (DTH) drill bits.
2. With high impact resistance and excellent wear resistance.
3. According to the different working conditions, Diamond DTH bits use different kinds of PDC insert sharps.
4. Stable footage efficiency, improve work efficiency and increase the benefits of 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&hardness&wear resistance, and longer service life(10-15 times tungsten carbide insert), and reduces the cost of DTH bits.
6. Strict quality control before delivering.

Application

Used on down-the-hole drill bits for mining high hardness formations.
