PDC (Polycrystalline Diamond Compact) drill bits are full-face drilling tools designed for efficient performance in coal mining, oilfield operations, water conservancy projects, hydropower construction, and building infrastructure. With decades of industry experience, we offer PDC bits in various sizes and specifications to meet diverse drilling requirements.

Note: Custom sizes available upon request to meet specific project requirements.

• Optimized crown profile designed for different formation characteristics with functional composite pieces for soft to medium hard formations
• Force-balanced cutting structure with asymmetric blades and deep chip grooves for higher rotary speeds
• High-quality steel base material with wear-resistant surfacing to prevent erosion
• Dynamic flow field simulation for optimized hydraulic design and enhanced cleaning/cooling performance

• Ensure clean well bottom free of sand and metal debris before installation
• Verify thread connections and nozzle installation integrity
• Start with low pressure and avoid sudden bit drops during initial drilling
• Use large displacement starter turntable with thorough well washing
• Begin with 40-60 RPM for at least 30 minutes for proper bottom hole formation
• Follow manufacturer recommendations while adjusting parameters based on actual formation conditions
• Maintain smooth, even operation throughout drilling process
• Monitor for signs of bit issues including reduced footage, pressure changes, or increased torque
