• Advanced Polycrystalline Diamond Compact (PDC) Technology: Engineered with premium PDC cutters featuring super-hard diamond composite materials. This advanced technology delivers exceptional wear resistance and impact toughness, significantly extending service life compared to conventional carbide bits while maintaining sharp cutting edges even under extreme downhole conditions.
• Optimized 3-Wing Design for Faster Penetration: The three-wing twist structure provides aggressive cutting action with advanced shearing and line-cutting functions. Compared to 4-wing configurations, this design offers faster drilling speeds in soft to medium-hard formations while maintaining excellent stability, making it ideal for time-sensitive geological exploration projects.
• Versatile Application Across Multiple Industries: Widely used in geological exploration, water well drilling, coalfield mining, subway construction, and geotechnical engineering. Suitable for drilling extremely soft to medium-hard formations (including limestone, sandstone, shale, and clay), with adaptability to complex geological conditions.
• Rugged Construction for Demanding Environments: Built from high-strength alloy steel with wear-resistant tungsten carbide inserts on cutting edges and gauge sides. Features integrated flushing holes for efficient debris removal and cooling, ensuring consistent performance in abrasive and challenging rock formations.
• Standard API Thread for Easy Rig Integration: Equipped with industry-standard API Reg pin/box thread connections (available in 2 3/8", 3 1/2", 4 1/2" API Reg, and other custom options) for secure attachment to common drill rods and downhole tools. Available in a range of diameters (50-444mm, including 75mm, 94mm, 113mm, 133mm, 153mm, 171mm, 200mm, 216mm, 251mm, 311mm, 403mm, 444mm) to match various borehole requirements and rig specifications, with options for both coring and non-coring applications.
