Application of PDC cutter
PDC cutters are widely used for petroleum and oil field PDC bit, geological PDC exploration bits, gas exploration bits, PDC coal mining drill bits.
PDC is mainly applicable for PDC drilling bit for drilling into soft and intermediate-hardness stratum.
Advantages of PDC cutters
New cutting surfaces will appear during the course of abrasion, which keeps effective cutting rocks
High strength, high hardness and high wearing property of diamond layer as well as good self-sharpening
PDC drilling bit made of such PDC will break up rocks depending on shearing action when it works, which is more effective than crushing of rocks by roller conebit or plowing and grinding of rocks by diamond impregnated bit
The serrate structure combination between polycrystalline diamond layer and hard alloy substrate allows more fixed combination between the two layers and more impact resistance of the whole PDC.
Correct use of PDC drill bits
PDC bits work best in large sections of homogeneous soft to medium hard formations.
Not suitable for drilling gravel layer and soft and hard interlaced formation.
It adopts low drilling pressure, high speed, and large displacement for drilling, and the drill bit has a good effect.
Before the drill bit goes into the well, the bottom of the well should be cleaned to ensure that there are no metal falling objects.
When the drill bit just goes into the well, it is necessary to use a small WOB and low rotational speed to run in harmony, and resume normal drilling after the bottom hole is formed.
PDC drill bits are integral drill bits without any moving parts and are suitable for high-speed turbine drilling.

1.PDC drill bit is super hard material combined with diamond and hard alloy under high temperature and high pressure.
2.It not only has the advantages of hard and durable from diamond, but also has the advantages of high impact resistance and big blade from hard alloy.
3.It greatly improves the drilling efficiency and is the ideal drill bit for the drill operation of medium & hard as well as super hard rock. The carrier of PDC bits is forged and pressed by first-class steel.
4. Its mechanical capacity is strengthened by fully automatic vacuum heat treatment equipment.
A. Selected higher quality diamond powder, improved the sintering technique, enhanced the bond combination strength between diamond grain;
B.Improved the inner structure of the sintered cavity, the pressure and temperature become more balance, which ensure the cutter has more stable performance;
C.Adopted a new type of carbide, which improved the weld strength;
D.Optimized the designation of joint face, which reduced the residual stress.
