PDC drilling bit
-- Replace the drill bit during operation, cutter weared out or complex geological conditions required special drill bit.
Our PDC drill bit is the right solution for you.
Polycrystalline diamond compact PDC cutter is mainly made of Polycrystalline diamond and tungsten carbide base.
PDC is made of diamond powder and cemented carbide substrate in the ultra-high pressure and high temperature sintering conditions, both with high hardness diamond, high wear resistance and thermal conductivity, but also has the strength of carbide and impact toughness, It is an ideal material for manufacturing cutting tools, drilling bits and other wear tools.
Structure of PDC drilling bit
The bottom is a carbide substrate, the top part of the black is diamond, but also the force of the entire product, is a super hard material.

Application of PDC drilling bit
PDC is a kind of composite material composed of diamond and hard alloy matrix. It has the characteristics of high hardness and good wear resistance. It is widely used in:
1. Oil and gas well drilling
2. Geological and mining drilling
3. Coal drilling
4. Machining tools.
The superiority of PDC cutter compared with normal tungsten carbide
1. High hardness, high abrasion resistance and high impact resistance.
2. 5-10 times longer useful life compared with normal tungsten carbide, obviously reduce the frequency of replace the drill bit.
3. Effective and stable drilling speed to protect the equipment and reduce the drilling cost(30%-40% overall cost)
Production Process of PDC cutter
1. Milling
2. Proportioning as required
3. Wet grinding
4. Dry--Granulation
5. Pressing
6. Sntering
7. Inspection
8. Packaging
Quality control of PDC drilling bit
