Core Product Advantages
Outstanding Compressive Strength
The reinforced conical geometry distributes drilling loads more efficiently, enabling the cutter to withstand extremely high compressive forces encountered in deep and hard-rock drilling operations.
Superior Impact Resistance
The diamond-enhanced structure and optimized stress distribution significantly reduce edge chipping and fracture risks caused by vibration and formation discontinuities.
Exceptional Wear Resistance
Premium-grade synthetic diamond materials provide long-lasting abrasion resistance, helping maintain cutter sharpness throughout extended drilling cycles.
Excellent High-Temperature Stability
Manufactured using advanced high-pressure high-temperature (HPHT) technology, the C3219 maintains structural integrity and cutting performance under elevated downhole temperatures.
Higher Rate of Penetration (ROP)
The conical profile concentrates cutting energy at the contact point, improving rock fragmentation efficiency and increasing drilling speed.
Extended Bit Service Life
Reduced wear, improved thermal stability, and enhanced impact resistance contribute to longer bit runs and lower replacement frequency, reducing overall drilling costs.
Precise Size Specifications
The C3219 cutter features a nominal diameter of 32 mm with a diamond table thickness optimized for demanding drilling environments. Its precision-engineered conical profile enhances force concentration during rock engagement while maintaining excellent structural stability. Dimensional tolerances are tightly controlled to ensure consistent performance and compatibility with a wide range of drill bit designs.
Material and Core Technology
Premium Synthetic Diamond Layer
Manufactured using high-quality synthetic diamond powders that provide outstanding hardness, wear resistance, and cutting efficiency.
Advanced HPHT Sintering Technology
Produced under carefully controlled ultra-high pressure and high-temperature conditions to achieve strong diamond-to-substrate bonding and superior mechanical properties.
Diamond-Enhanced Conical Design
The optimized conical geometry improves stress distribution, enhances impact resistance, and increases rock-breaking efficiency in hard and abrasive formations.
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.
