• Optimized 4-Wing Arc-Angle Design for Hard Rock – Engineered with a concave arc-angle blade profile to enhance cutting efficiency and stability in granite, basalt, and other hard rock formations, reducing vibration and improving penetration rates.
• Premium Polycrystalline Diamond Compact (PDC) Cutters – Features high-grade PDC cutters that deliver exceptional wear resistance and impact toughness, ensuring long service life in demanding drilling conditions such as coal mines, water wells, and mineral exploration.
• Efficient Hydraulic Structure for Chip Removal – Strategically placed water jets and large chip evacuation slots help cool the cutters, remove debris quickly, and prevent bit balling, allowing for continuous, high-performance drilling.
• Versatile Applications in Mining & Water Wells – Suitable for drilling in soft to very hard formations (UCS up to 25,000 psi), including sandstone, limestone, shale, and hard abrasive rock, making it ideal for coal mine gas drainage, water well development, and geotechnical exploration.
• Build with Standard API Thread Connection – Constructed with a robust steel body and available in various sizes (4–12 inches) with standard pin or box connections, providing reliable torque transmission and easy integration with most rotary drill rigs.
