Advanced sintering technology enhances heat resistance, allowing stable performance under elevated drilling temperatures.
Longer Service Life
Optimized diamond table thickness and strong carbide substrate bonding contribute to significantly increased cutter lifespan.
Higher Drilling Efficiency
Maintains structural integrity during operation, improving penetration rates while lowering overall drilling costs.
Precise Size Specifications
DB1623 features a nominal diameter of 16 mm and a total height of approximately 23 mm. The cutter is manufactured with strict dimensional tolerances to ensure excellent consistency and compatibility with various drill bit designs. Customized dimensions, diamond layer thicknesses, chamfer configurations, and interface structures are available upon request.
Material and Core Technology
Premium Polycrystalline Diamond Layer
Manufactured using selected synthetic diamond powders under ultra-high pressure and high-temperature conditions to achieve exceptional hardness and wear resistance.
High-Toughness Tungsten Carbide Substrate
Utilizes premium cemented carbide substrates that provide excellent mechanical support, impact resistance, and bonding strength.
Advanced HPHT Sintering Technology
State-of-the-art high-pressure high-temperature sintering technology ensures strong diamond-to-carbide bonding and superior 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.
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.
