PDC Bit Cutter Characteristics
Non-planar interface structure to prevent delamination
Using the patented ridge interface design, the bonding area of diamond layer and cemented carbide substrate is increased by 30%, the internal stress concentration is effectively eliminated, the shear strength is increased to more than 650 MPa, and the stratification phenomenon is fundamentally eliminated.
Deep cobalt removal process to maintain hardness
Through the deep decobalting treatment of 100-200 microns, the catalyst metal between the diamond grids is removed, and the critical point of thermal stability of PDC bit cutter is increased from 700°C to 750°C, and the hardness is still maintained during dry drilling or insufficient cooling.
Optimized chamfer design to reduce chipping rate
Provide a 45 ° double chamfer design. Field tests have proved that the geometry can disperse 40% of the axial impact load and reduce the chipping rate by 60% when drilling into gravel or soft and hard cross formations.
Multi-particle diamond powder to extend drill bit life
Mix 2-30 micron multi-grain diamond powder, the sintering density reaches more than 96%. Compared with single particle size products, the wear resistance ratio is as high as 400: 1, which greatly prolongs the life of drill bit footage.
Polishing treatment to prevent mud-bag drill bit
The surface roughness Ra of the composite sheet was controlled within 0.1 μm, and the friction coefficient was reduced to 0.05. This feature significantly reduces the friction and heat generation during cutting, and helps to quickly discharge the cuttings and prevent the mud from wrapping the drill bit.
100% ultrasonic nondestructive testing
Each piece of factory PDC bit cutter is C- Scan ultrasonic scanned to ensure that there are no micro cracks or voids (Pores) inside the diamond layer, ensuring the consistent performance of the batch product under the bottom hole pressure of 30,000 PSI.

PDC Bit Cutter Contrast Point
In deep and ultra-deep well drilling operations, ordinary composite sheets often fail early due to thermal degradation and impact fatigue. By optimizing the microstructure, our PDC bit cutter significantly improves toughness while maintaining high wear resistance, solving the contradiction between hardness and toughness in the industry.
Solve the problem of chipping in hard formation drilling
In view of the high frequency impact common in the operation of quartz sandstone or conglomerate layer, the high toughness matrix of this product with double chamfered edge design can absorb the energy generated by the vibration of the drill string, reduce the chipping rate of cutting teeth by 55%, and avoid the loss of hundreds of thousands of dollars of construction period caused by frequent tripping out and changing heads.
Solve the problem of thermal wear in high temperature environment of deep well
Common PDC teeth are prone to graphitization inversion for conditions where the bottom hole temperature exceeds 150°C and frictional heat generation is severe. Our deep cobalt removal technology removes the easily expandable cobalt catalyst, allowing the PDC bit cutter to maintain cutting sharpness at a high temperature of 750°C, solving the pain point of the drill bit's slow feed in long-section abrasive formations.
Solve the problem of catastrophic failure caused by delamination of composite sheets
In view of the huge shear force generated during high torque drilling, the traditional flat-bottom joint surface is easy to peel off. This product adopts mesh claw interface, which increases the binding force between diamond layer and alloy matrix to 1.5 times of the industry average level, and completely solves the problems of bottom hole falling and bit scrapping caused by delamination of composite sheet.

Downhole tool maintenance and refurbishment service provider
Suitable for repair factory of used drill bits or worn drill bits. The standardized dimensional tolerance (diameter ± 0.05mm) makes the process of replacing worn teeth more convenient and can restore more than 90% of the original cutting performance of the drill bit at a lower cost.
Instructions for use of PDC Bit Cutter
Cleaning before welding
Use absolute ethanol or acetone to thoroughly clean the bottom of the PDC bit cutter and the drill hole to ensure that there is no oil, scale or dust residue. Cleanliness directly affects the wetting angle and bonding strength of the brazing seam to prevent virtual welding.
strictly control welding temperature
When using high-frequency induction brazing, the temperature must be strictly monitored. It is recommended that the maximum heating temperature should not exceed 720°C and the high temperature residence time should be controlled within 40 seconds to prevent thermal damage (graphitization) to the diamond layer.
Selection of Flux and Solder
It is recommended to use a low-temperature silver solder sheet with a silver content of 40%-50%, combined with a special fluorine-containing active flux. This ensures excellent flowability and permeability at lower temperatures to fill the interdental space.
Post-weld slow cooling process
After the welding is completed, it is strictly prohibited to immediately water or air cooling. The drill bit should be placed in asbestos powder or insulation box for slow cooling to release welding residual stress and prevent micro-cracks in the composite sheet.

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.
FAQ
What kind of rock formation is your PDC bit cutter suitable for drilling?
Our products cover several series. The standard petroleum grade series is mainly for medium-hard to hard formations (compressive strength 100-200 MPa), such as sandstone, limestone and dolomite. For extremely hard or abrasive formations, we recommend specific impact-enhanced models.
What is the main difference between 1308 and 1313 models?
The main difference is the total height and the thickness of the diamond layer. The total height of the 1308 is usually 8mm, and the diamond layer is thinner, which is mostly used for geological exploration or soft formation. The total height of the 1313 is 13mm, with thicker diamond layer and stronger alloy support, which is more suitable for high-strength cutting environment in oil drilling.
How do you ensure the quality consistency of each batch of products?
We implement strict quality control system. In addition to regular dimensional inspections, we conduct destructive sampling tests (including vertical drop weight impact tests and drum wear tests) on each batch of products, and conduct 100% ultrasonic scanning on all finished products to ensure that there are no internal delamination defects.
Can you provide customized chamfer angle?
You can. Standard chamfers are usually 45 ° x 0.3mm, but we can customize double chamfers, large chamfers or special edge geometries to balance cutting efficiency and impact resistance according to the customer's specific formation needs.
What are the recommended shelf life and storage conditions for the product?
It is recommended to store in a dry, room temperature environment to avoid acid and alkali corrosion environment. Although the physical properties of PDC bit cutter are stable, it is recommended to use it within 24 months after leaving the factory in order to prevent the oxidation of the silver solder layer or the influence of moisture on the subsequent welding performance.
What causes the diamond layer to turn black when welding?
Blackening of the diamond layer is usually caused by overheating or oxidation. This means that the welding temperature exceeds 750°C or the heating time is too long, resulting in carbonization or graphitization of the diamond layer.
Please feel free to contact us. We look forward to hearing from you.
