Core Product Advantages
Outstanding Compressive Strength
Engineered to withstand extreme downhole pressures, DB1215 maintains structural integrity during high-load drilling operations.
Superior Impact Resistance
The optimized diamond-carbide interface effectively absorbs impact energy, reducing cutter chipping and breakage in complex formations.
Excellent Wear Resistance
Premium polycrystalline diamond material provides exceptional abrasion resistance, significantly extending cutter lifespan.
High Thermal Stability
Designed to operate under elevated drilling temperatures while maintaining cutting efficiency and structural reliability.
Faster Rate of Penetration (ROP)
Sharp cutting edges and stable cutting geometry help improve drilling efficiency and reduce operational costs.
Longer Bit Service Life
Reduced wear and breakage result in fewer bit replacements, minimizing downtime and maximizing productivity.
Precise Size Specifications
Full product range with multiple specifications available, including standard models of 13mm, 19mm and 22mm, as well as thickened and heightened DE series. All products are manufactured with a strict tolerance of ±0.02mm, ensuring tight fitting installation, stable operation and no vibration.
Material and Core Technology
Advanced HPHT Sintering Technology
Manufactured using high-pressure high-temperature sintering processes to create a highly bonded diamond structure with superior mechanical properties.
Premium Diamond Layer
Utilizes selected synthetic diamond powder with optimized grain distribution for enhanced wear resistance and cutting efficiency.
High-Toughness Tungsten Carbide Substrate
The tungsten carbide base provides excellent support for the diamond layer, improving impact resistance and overall durability.
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.
