PDC Cutters for Drilling characteristics
Prevent delamination of diamond layer
With the unique interface design of ridged or corrugated cemented carbide and diamond layer, the contact area is increased by 40%, which effectively relieves the residual stress in the drilling process. This design increases the shear strength to more than 550 MPa, which fundamentally prevents the diamond layer delamination and shedding phenomenon that is common in high impact drilling operations.
Applicable deep drilling
In view of the failure of PDC cutters for drilling in high temperature environment, we have implemented the decobalting treatment with a depth of more than 0.3mm. After removing the catalyst metal cobalt, the micro-cracks caused by the difference between the thermal expansion coefficients of cobalt and diamond are eliminated, so that the composite sheet can still maintain 95% of the initial hardness at a dry cutting temperature of 750°C, which greatly meets the needs of deep well geothermal drilling.
The mixed formula is not easy to crack
The perfect balance of hardness and toughness is achieved by scientifically matching the fine grains of 4 μm with the coarse grains of 25 μm. Fine grains fill the gap to provide compactness, so that the wear resistance is improved by 200 compared with the standard formula. The coarse grain construction framework provides impact resistance and ensures that it is not easy to crack when drilling in hard rock formations with compressive strength exceeding 200 MPa.
100% ultrasonic nondestructive testing
Every piece of PDC cutters for drilling is ultrasonically scanned with high precision before it leaves the factory. We implement strict ASTM industry standards to eliminate any internal pores or microcracks that exceed 0.1mm in diameter. This zero-defect delivery standard ensures that drill bit manufacturers have less than 0.01 percent rejects when using automated brazing lines.
Applicable to complex geological structures
Provide 45 ° or 30 ° pre-chamfer, and the chamfer surface finish is controlled within Ra 0.2. After testing, this precision chamfer design can effectively disperse the initial impact force at the moment when the drill bit cuts into the rock, and reduce the early damage rate of PDC cutters for drilling by 60%, which is especially suitable for complex geological structures with changeable interlayers.
Uniform welding strength
The high-precision cylindrical grinding process is adopted to ensure that the diameter tolerance is strictly controlled within ± 0.05mm and the height tolerance is controlled within ± 0.1mm. This high consistency makes the drill bit manufacturer in the high-frequency induction brazing, the composite sheet and the tooth hole with the clearance is always in the best range of 0.1-0.15mm, to ensure the uniformity of welding strength.

PDC Cutters for Drilling Comparison Point
Compared with traditional cemented carbide teeth or low-end polycrystalline diamond products, this PDC cutters for drilling shows better retention rate in extremely harsh downhole environment through microstructure optimization and strict post-treatment process.
Eliminate “thermal degradation” failure caused by high temperature
Aiming at the problem of tooth surface softening caused by cutting heat accumulation in deep well drilling, our deep decobalt process cuts off the vicious circle of heat conduction. Compared with ordinary composite sheets without deep cobalt removal treatment, the wear ratio (Wear Ratio) of the product remains above 300,000 after continuous friction heating to 700°C, thus solving the pain point of sharp drop in the footage speed of the drill bit after long-term drilling.
Solve the “impact chipping” caused by hard interlayer”
For the non-uniform formation such as conglomerate or quartz sandstone, the common composite sheet is prone to brittle fracture. This product uses optimized non-planar interface bonding technology to disperse the interface shear stress so that the composite sheet can withstand vertical impact energy up to 450 Joules. This solves the pain point that the drill bit needs to be frequently tripped to replace the drill bit due to the chipped teeth of the composite piece when the drill bit crosses the soft and hard alternating strata.
Avoid “hidden thermal damage” in the welding process”
In order to solve the problem of scrap due to the poor thermal stability of the composite sheet in the brazing process of the drill manufacturer, we used high-purity micron-grade diamond powder raw materials and sintered it twice under high pressure. The product can withstand a short brazing temperature of 780°C without graphitization, solving the problem of high scrap rate and quality uncertainty caused by thermal damage in the production assembly process.
PDC Cutters for Drilling Applicable Crowd
Oil and Gas PDC Bit Manufacturer
Enterprises that focus on the production of steel body or carcass PDC bits. This type of customer needs PDC cutters for drilling with extremely high impact and heat resistance to meet the needs of long-distance directional drilling in deep wells, horizontal wells, and shale gas development, ensuring that the drill bit maintains a high ROP (rate of penetration) at several kilometers downhole.
Geological exploration and mining bit manufacturers
Production for coal mine gas drainage hole, geological core drill manufacturers. This group is concerned about the wear resistance and cost performance of the product, and requires the composite sheet to be able to maintain the sharpness of the cutting edge in the sandstone or granite strata with strong abrasive properties and reduce the downtime of the drilling process.
Trenchless Engineering (HDD) Tool Suppliers
An enterprise that manufactures horizontal directional drilling reamers. Due to the complex and invisible operating conditions of the reaming operation, these customers rely heavily on the structural reliability of the PDC cutters for drilling to prevent tooth drop accidents when crossing rivers or urban pipe networks, avoiding the risk of huge project delays.
Manufacturers of down-the-hole hammers (DTH) and special tools
Engineering team developing tools for special hard rock crushing. This kind of application is usually accompanied by high frequency vibration, which requires the composite sheet not only to have the hardness of diamond, but also to have the overall toughness close to that of cemented carbide. Customized chamfering and special-shaped structure design are required to match the special tooth distribution scheme.
Instructions for use PDC Cutters for Drilling
Brazing temperature control
When welding the PDC cutters for drilling to the bit body, it is important to strictly control the heating temperature and time. It is recommended that the brazing temperature should not exceed 720°C, and the high temperature holding time should be controlled within 30 seconds to prevent the diamond layer from being reversed (graphitized) and causing a permanent decrease in hardness.
Selection of flux and solder
It is strongly recommended to use high silver solder (such as BAg-3 or BAg-4) with 40%-50% silver content, combined with low temperature fluoride flux. This combination has good fluidity and wettability, can effectively fill the gap between the composite sheet and the tooth hole, ensure that the shear strength reaches more than 200 MPa, and prevent the downhole tooth from falling.
Specification for post-weld cooling
Water cooling or oil cooling quenching of PDC cutters for drilling is strictly prohibited after brazing. It must be covered with thermal insulation cotton or placed in vermiculite for slow cooling to release the residual thermal stress of welding and prevent the separation of hard alloy substrate and diamond layer due to rapid cooling.
Storage and handling
Although the hardness of the composite sheet is extremely high, it is very sensitive to the impact of an instant hard object. In the process of storage and transportation, the original independent flexible packaging must be retained to avoid the collision between the composite sheets and the cutting edge collapse (Chipping). The storage environment should be kept dry to prevent the oxidation and rust of the cemented carbide substrate.

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.
How hard rock can your PDC cutters for drilling withstand?
Our high-performance series is designed for complex formations and is recommended for medium-hard to hard rock formations with compressive strength (UCS) ranging from 15,000 psi to 25,000 psi. For extremely hard abrasive formations above 30,000 psi, we recommend a specific 19mm or 16mm thick diamond layer type.
What is the main application difference between 1308 and 1613 models?
The 1308 model has a smaller diameter and high tooth density, and is usually used for soft to medium hard formation bits that require high ROP; while the 1613 model has a larger diameter, large cutting volume, and is more wear-resistant. It is suitable for medium hard and abrasive formations that require higher durability. It is currently the mainstream choice for deep well drilling.
Do you provide profiled PDC cutters for drilling (e. g., axe or ridge)?
Yes, in addition to standard flat teeth, we provide special-shaped structures such as axe and cone. By changing the cutting geometry angle, special-shaped teeth can replace “cutting” with “plowing”, which has been proved to improve the drilling efficiency by more than 20% in specific hard rock formations.
What data does the product quality inspection report contain?
Each shipment is accompanied by COA report, including wear ratio data, drop weight impact test results, C- Scan ultrasonic internal flaw detection map and dimensional tolerance test records, fully in line with API drill manufacturing standards.
How long is the delivery time for ordering non-standard size PDC composite sheets?
For standard models (e. g. 1308, 1613, 1913), we usually keep stock in stock. For PDC cutters for drilling with custom chamfers or non-standard diameters, it usually takes 3-4 weeks of production cycle from mold confirmation to final delivery to ensure the integrity of the sintering and post-processing processes.
Can your cobalt removal depth be customized?
The standard deep decobalification depth is controlled between 0.15 mm-0. 3mm, which is sufficient for most high temperature drilling. If your application involves extreme geothermal environments, we can customize the ultra-deep cobalt removal process with a depth of 0.5mm, but this will slightly affect the impact resistance and need to be balanced according to the specific working conditions.
