The reinforced cutter structure withstands heavy drilling loads and high downhole pressures without compromising cutting performance.
Excellent Impact Resistance
Engineered to resist chipping and fracture caused by vibration and formation changes, ensuring reliable drilling performance.
Outstanding Wear Resistance
The premium polycrystalline diamond layer significantly reduces wear rates, extending cutter and drill bit service life.
Superior Thermal Stability
Advanced HPHT technology enhances heat resistance, allowing stable performance under elevated drilling temperatures.
Improved Drilling Efficiency
Optimized cutting geometry increases rock-breaking efficiency and penetration rates, reducing drilling time.
Longer Service Life
Exceptional durability helps minimize bit replacement frequency and lowers overall drilling costs.
Precise Size Specifications
The CB1319 cutter features a nominal diameter of 13 mm and an overall height of 19 mm. The carefully engineered diamond table thickness and chamfer design provide an excellent balance between aggressiveness and durability. Precision manufacturing ensures consistent dimensional accuracy, while customized sizes and diamond layer configurations are available to meet specific drilling requirements.
Material and Core Technology
Premium Polycrystalline Diamond Layer
Produced from high-purity synthetic diamond particles, the PCD layer delivers exceptional hardness, wear resistance, and cutting performance.
High-Toughness Tungsten Carbide Substrate
The carbide substrate provides superior structural support, shock absorption, and impact resistance during drilling operations.
Advanced HPHT Sintering Technology
The diamond layer and carbide substrate are permanently bonded through advanced HPHT processes, creating excellent interface strength and long-term reliability.
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.
