Core Product Advantages
Superior Compressive Strength
The high-strength tungsten carbide substrate provides excellent load-bearing capability, ensuring reliable performance under heavy cutting forces.
Exceptional Impact Resistance
The truncated structure reduces stress concentration and significantly improves resistance to cracking and edge chipping during impact operations.
Outstanding Wear Resistance
The premium diamond layer offers superior abrasion resistance, extending cutter life in highly abrasive working environments.
Excellent High-Temperature Stability
Advanced thermal-resistant technology enables the cutter to maintain cutting performance under elevated operating temperatures.
Longer Tool Service Life
Optimized diamond-to-carbide bonding technology minimizes premature failure and maximizes operational lifespan.
Improved Cutting Efficiency
The engineered cutting geometry enhances rock-breaking performance, reducing energy consumption and increasing productivity.
Precise Size Specifications
DH1216 features a standard diameter of 12 mm and an overall height of 16 mm. The truncated diamond table is designed to balance wear resistance and impact toughness, providing optimal performance in mining and engineering applications. Customized dimensions, diamond layer thicknesses, truncation heights, and chamfer configurations are available according to customer requirements.
Material and Core Technology
Premium Polycrystalline Diamond Layer
Manufactured using high-purity synthetic diamond powder to achieve exceptional hardness, wear resistance, and cutting performance.
High-Strength Tungsten Carbide Substrate
Utilizes premium tungsten carbide material to provide excellent toughness, compressive strength, and impact resistance.
Advanced HPHT Sintering Technology
Employs industry-leading High Pressure High Temperature technology to create a strong metallurgical bond between the diamond layer and carbide substrate for superior durability 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.
