DB1421 maintains structural integrity and cutting efficiency even under elevated drilling temperatures, reducing thermal degradation risks.
Consistent Drilling Performance
Precision manufacturing ensures stable cutting behavior, improved drilling efficiency, and smoother bit operation throughout the drilling cycle.
Extended Service Life
Enhanced diamond retention and strong substrate support contribute to a longer operational lifespan, lowering overall drilling costs.
Precise Size Specifications
DB1421 features a nominal diameter of 14 mm and an overall height of 21 mm. The cutter is manufactured with strict dimensional tolerances to ensure compatibility with various PDC drill bit designs. Customized dimensions, chamfer configurations, and diamond table thicknesses are available to meet specific drilling requirements and application conditions.
Material and Core Technology
High-quality synthetic diamond particles are sintered under extreme pressure and temperature conditions to achieve exceptional hardness and wear resistance.
The optimized interface between the diamond table and tungsten carbide substrate enhances impact resistance and minimizes delamination risks.
State-of-the-art production equipment and strict quality control procedures ensure consistent product quality and reliable field performance.
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.
