DB1623 Diamond Spherical Compound Teeth
Video
DB1623 Diamond Dome PDC Cutter is a premium dome-shaped polycrystalline diamond compact (PDC) cutter specifically engineered for high-impact drilling environments. Compared with conventional flat PDC cutters, the spherical dome structure distributes stress more evenly across the cutting surface, significantly improving impact resistance and durability.
Designed for demanding drilling applications, DB1623 delivers exceptional performance in hard, abrasive, and heterogeneous formations, making it an ideal choice for oil & gas drilling bits, mining tools, geological exploration equipment, and foundation engineering tools.

Applicable Strata
The DB1623 Dome PDC Cutter performs exceptionally well in:
- Hard limestone
- Granite formations
- Quartz-rich sandstone
- Dolomite
- Abrasive formations
- Interbedded formations
- Fractured rock layers
- High-impact drilling environments
Its unique dome geometry helps reduce cutter chipping and premature failure when drilling through challenging geological conditions.
Core Product Advantages
Outstanding Compressive Strength
The dome-shaped structure effectively disperses drilling loads, enabling superior resistance to compressive stress and reducing cutter breakage.
Excellent Impact Resistance
Engineered for highly demanding drilling conditions, DB1623 withstands repeated impacts and shock loads better than conventional flat PDC cutters.
Superior Wear Resistance
High-quality polycrystalline diamond layers provide long-lasting wear protection, extending bit life and reducing replacement frequency.
Exceptional Thermal Stability
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
Manufactured using selected synthetic diamond powders under ultra-high pressure and high-temperature conditions to achieve exceptional hardness and wear resistance.
Utilizes premium cemented carbide substrates that provide excellent mechanical support, impact resistance, and bonding strength.
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.
