PDC Drill Bit Cutters characteristics
Deep cobalt removal process to improve thermal stability
Through advanced acid leaching and cobalt removal treatment technology, the residue of catalyst metal cobalt in the diamond layer is removed, so that the heat-resistant temperature of PDC drill bit cutters is increased from the ordinary 700 degrees Celsius to more than 750 degrees Celsius, and thermal degradation or carbonization of the diamond layer is prevented under the working conditions of high-speed dry drilling or severe frictional heat generation.
Non-planar interface bonding technology to enhance shear resistance
The unique non-planar mesh or corrugated bonding interface design is adopted between the diamond layer and the tungsten carbide substrate, which increases the bonding area by 30% compared with the traditional planar bonding. This structure can effectively disperse the shear stress in the drilling process, increase the shear strength of the composite sheet to more than 400 MPa, and greatly reduce the risk of delamination and shedding.
High density diamond powder formula guarantees wear resistance
Selected particle size distribution in the ten to forty microns of high-grade synthetic diamond powder, after more than eight gigapascals ultra-high pressure sintering, diamond volume content of more than 92%. According to the standard wear test, the wear ratio is as high as four hundred thousand to one, and the volume loss rate of cutting teeth is reduced by 50% in the sandstone formation with strong abrasiveness.
Chamfer geometry design optimizes cutting efficiency
Provide standardized and customized chamfer design, chamfer angle control in 45 degrees, width tolerance control within 0.05mm. This precise chamfer geometry can not only reduce the instantaneous impact damage when the drill bit enters the rock, but also improve the rock breaking efficiency 20% while maintaining the aggressiveness.
Strict dimensional tolerance control to ensure welding accuracy
Using full-automatic cylindrical grinding and plane grinding process, the diameter tolerance of PDC drill bit cutters is strictly controlled at plus or minus 0.05mm, and the height tolerance is controlled at plus or minus 0.1mm. The high-precision dimensional consistency ensures that the welding on the bit body is centered, reducing the stress concentration caused by installation errors.

PDC Drill Bit Cutters instructions
Temperature Control of High Frequency Induction Brazing
When welding the PDC drill bit cutters to the bit body, the brazing temperature must be strictly controlled. It is recommended to use high-frequency induction heating. The maximum heating temperature shall not exceed 720 degrees Celsius, and the holding time shall be controlled within 30 seconds to prevent the diamond layer from graphitizing due to overheating and causing performance failure.
Selection of flux and silver solder chip
It is recommended to use silver solder pieces with silver content of 40% to 50%, combined with special low-temperature fluoride flux. When the flux is applied, it should be ensured that the coverage is uniform but not excessive, so as to ensure that a high-strength metallurgical bond is formed between the cutting tooth matrix and the bit socket to prevent tooth drop during drilling.
Setting of the caster angle of the cutting tooth
During design and installation, the back angle should be adjusted according to the hardness of the target formation. For soft formations, it is recommended to set a back angle of ten to fifteen degrees to increase aggressiveness; for hard formations or abrasive formations, it is recommended to set a back angle of more than twenty degrees to protect the cutting edge and disperse the impact load.
Protective measures for storage and handling
Although the PDC drill bit cutters is extremely hard but brittle, it is strictly prohibited to directly collide with each other. During storage, the environment should be kept dry to prevent oxidation of the cemented carbide substrate. Plastic foam boxes or soft materials with independent compartments must be used during handling to avoid microcracks on the edge of the diamond layer.

FAQ And Contact Us
Welcome to our Frequently Asked Questions page. We have compiled answers to common questions you may have, hoping to provide you with clear and quick solutions. If you cannot find the information you need here, please feel free to contact our customer support team.
Q1: What is the thermal limit of PDC drill bit cutters?
The heat-resistant temperature of the standard composite sheet is usually about 700 degrees Celsius, while the thermal stability of the high-performance composite sheet after deep decobalt treatment can reach 750 degrees Celsius or even higher, which can adapt to more harsh deep well high temperature environment.
Q2: How to choose the right chamfer shape?
The chamfer is mainly used to disperse the impact force. The small chamfer has better cutting sharpness and is suitable for fast drilling in soft formations. The large chamfer or double chamfer design sacrifices part of the aggressiveness in exchange for stronger impact resistance and is suitable for drilling in hard formations or interlayers.
Q3: Can this cutting tooth be recycled?
It is generally not recommended to reuse old teeth on drill bits with high performance requirements. Although the appearance may be intact, the internal diamond lattice structure may have been slightly damaged after underground high temperature, high pressure and stress fatigue, and reuse can easily lead to early failure.
Q4: What are the common forms of failure?
The most common forms of failure include flat wear (normal wear), chipping (excessive impact load), delamination (failure of interfacial bonding or thermal stress damage), and thermal cracking (insufficient cooling or excessive weight-on-bit leading to runaway frictional heat generation).
Q5: What is the effect of drilling fluid on PDC drill bit cutters?
Adequate drilling fluid flow and reasonable nozzle design are essential. Drilling fluid is not only used for chip removal, but also the main cooling medium for cutting teeth. Insufficient cooling can cause the local temperature to instantaneously exceed the thermal stability limit of the diamond, causing “hot check” damage.
Q6: What is the difference between a planar interface and a non-planar interface?
The planar interface has simple manufacturing process and low cost, which is suitable for shallow wells and soft formations; non-planar interfaces (such as claw-shaped and corrugated) significantly improve the shear and impact resistance by increasing the contact area and mechanical locking force, and are suitable for deep Wells and complex formations.
