DTH Hammer Bit PDC Inserts for Mining and Water Well Drilling
PDC inserts are crafted from tungsten carbide substrates and diamond powder sintered under extreme temperature and pressure. They integrate the rugged impact properties of tungsten carbide with the exceptional wear resistance of diamond. This unique composition significantly reduces thermal fatigue failure during rock breaking, ensuring longevity and efficiency.
These inserts are specifically engineered for down-the-hole (DTH) hammer drilling, prioritizing high-impact resistance and superior wear performance. They are ideal for navigating hard rock and abrasive formations, maintaining stable cutting efficiency even under high-frequency impact.
Key Technical Advantages
High Impact Strength
Optimized diamond structure and carbide substrate withstand repeated DTH hammer impacts without chipping or fragmentation.
Superior Wear Resistance
High-density polycrystalline diamond layer ensures a long service life when drilling through hard and abrasive rock materials.
Thermal Stability
Maintains peak cutting performance under the intense heat generated during high-speed impact drilling operations.
Stable Cutting Performance
Reduces the risk of insert breakage, significantly improving overall drilling efficiency in challenging DTH applications.
Available Sizes & Specifications
We offer a wide range of specifications to meet diverse user needs. Customized production and processing are available based on specific drawings and requirements regarding size, chamfer, and diamond thickness.
