Core Product Advantages
Superior Compressive Strength
The tungsten carbide substrate provides exceptional structural support, enabling the cutter to withstand extreme compressive loads during drilling operations.
Excellent Impact Resistance
Optimized diamond-table bonding technology significantly improves resistance to impact and cutter chipping, especially in complex formations.
Outstanding Wear Resistance
The high-density diamond layer offers exceptional abrasion resistance, extending bit life and reducing replacement frequency.
High Temperature Resistance
Advanced thermal stability technology enables the cutter to maintain cutting performance under elevated drilling temperatures.
Longer Service Life
Enhanced diamond crystal structure minimizes premature wear and cutter failure, ensuring consistent drilling performance over extended periods.
Higher Drilling Efficiency
Optimized cutting geometry improves rock-breaking efficiency, resulting in faster penetration rates and lower drilling costs.
Precise Size Specifications
DW1214 PDC Cutter features a standard diameter of 12 mm and a total height of 14 mm, making it suitable for various drill bit designs and manufacturing requirements. Custom dimensions, chamfer angles, diamond layer thicknesses, and cutter geometries are available upon request to meet specific drilling applications and geological conditions.
Material and Core Technology
Premium Polycrystalline Diamond Layer
Manufactured from selected synthetic diamond powders under HPHT conditions, providing superior hardness and wear resistance.
High-Strength Tungsten Carbide Substrate
Engineered with high-quality tungsten carbide to enhance toughness, impact resistance, and load-bearing capability.
Advanced HPHT Sintering Technology
Utilizes cutting-edge high-pressure, high-temperature sintering processes to achieve exceptional diamond-substrate bonding strength and thermal stability.
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.
