PDC inserts for DTH bits

This series of PDC inserts by using specialized interface optimized technology and manufacturing process to adopt different designs and different applications. Except for the excellent impact resistance properties, the PDC inserts also have high wear and heat resistance.HTHP press, and double or three diamond layer design.
Usage: For DHT drill bits of mining in hardness formations.
Feature: Long life, more than 10-15 times compared with the normal tungsten carbide insert; High-efficiency drilling depth; Equipment usage rate; Reduce the labor intensity; To save fuel and electricity.
Shape: Dome/Round/Spherical /Conical/ Parabolic/Semi-ballistic /Flat/Sharp tooth type.

Description

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.

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.
