Core Product Advantages
Ultra-high Wear Resistance
Adopting HPHT sintered diamond layer with a hardness of HV10000+, its service life is 25% longer than ordinary composite teeth, reducing the frequency of drill bit replacement and downtime costs effectively.
Excellent Impact Resistance
It remains crack-free after 1200 times of 50J impact tests. The high-quality cemented carbide substrate and conical structure disperse impact force, adapting to high-vibration complex geological conditions and reducing equipment damage risk by 40%.
Efficient Rock-breaking Capacity
The conical design reduces the contact area with rock, increasing unit pressure by 30%. It easily breaks through strata with hardness of 8–12 degrees, improves drilling speed by 20–30%, and shortens the construction period.
Enhanced Drill Bit Stability
As an auxiliary component of PDC drill bits, it assists in formation fracturing, reduces friction between the drill bit and the wellbore, and promotes stable drilling to avoid deviation.
Precise Dimensional Interchangeability
Strict CNC machining ensures consistent dimensions, with high compatibility with standard PDC drill bits, realizing fast installation and replacement.
Reliable Thermal Stability
It performs stably under high-temperature drilling conditions, resisting diamond graphitization and layer separation, suitable for continuous long-hour drilling operations.
Precise Size Specifications
C1113 conical diamond composite tooth adopts standard fixed specifications with a diameter of 11.176mm, a total height of 13.716mm, a dome radius of 2.0mm, and an exposed height of 5.5mm. All products are processed with precision machining to control tight tolerances, featuring good consistency and interchangeability, and can be perfectly assembled with various conventional PDC drill bits for oil, gas, mining and geological engineering.
Material and Core Technology
Core Material
The working layer uses high-purity micron synthetic diamond powder, and the substrate is made of ultra-fine grain cemented carbide with optimized formula, balancing high hardness and excellent toughness.
HPHT Metallurgical Bonding Technology
Sintered under ultra-high temperature and pressure, the diamond layer and carbide substrate form a seamless metallurgical bond, eliminating delamination and ensuring structural stability under heavy load.
Precision Conical Molding & Stress Optimization
CNC machined conical profile and low-residual-stress treatment reduce stress concentration, further improving impact resistance and service life in complex formations.
Application Field
Oil & Gas Drilling
Suitable for shallow to medium-deep well operations on land. Works well in tight sandstone, interbedded strata and gravel-bearing formations. High temperature resistance avoids carbonization and delamination, reducing bit replacement and overall drilling cost.
Mining Drilling & Exploration
Ideal for mineral prospecting, tunnel drilling and mine water well projects. Perfect for high-abrasive hard rock such as granite and quartzite. Excellent impact resistance prevents edge chipping, serving longer life in fractured mining formations.
Geological Exploration & Sampling
High dimensional accuracy ensures stable drilling and regular borehole. Guarantees complete formation core sampling, fully meeting high-precision geological survey and resource exploration requirements.
Water Well & Infrastructure Engineering
Widely used in deep water wells, pile foundation drilling and construction projects. Efficient penetration in common rock layers, low wear and stable performance for long-time continuous site operation.
Universal Bit Matching
Compatible with mainstream PDC bits, core bits and drilling tools with good interchangeability. Custom sizes and chamfers are available to meet non-standard matching demands for different projects.
