• Advanced PDC Technology for Superior Hard Rock Penetration: Engineered with high-quality Polycrystalline Diamond Compact (PDC) cutters brazed onto a alloy steel body. This construction delivers exceptional wear resistance and thermal stability, enabling efficient drilling in hard rock formations such as granite, basalt, and limestone while significantly extending service life compared to traditional tungsten carbide bits .
• Optimized 4-Wing Multi-Fluted Design for Stability: The four-wing blade configuration evenly distributes cutting forces, reducing vibration and improving hole straightness. This design enhances chip evacuation efficiency by up to 30%, minimizing downtime for clearing debris and ensuring smoother, more stable drilling operations in abrasive environments .
• Integrated Central Fluid Passage for Effective Cooling: Features a strategically engineered central hole for drilling fluid circulation. This system provides continuous cooling and lubrication directly to the cutting interface, reducing heat buildup during prolonged operation, preventing thermal cracking, and maximizing tool longevity in high-temperature drilling scenarios .
• Versatile Performance for Medium to Hard Rock Formations: Suitable for a wide range of demanding applications including mining, quarrying, water well drilling, and geotechnical exploration. The bit’s cutting structure is designed to deliver consistent penetration rates in formations with a Protodyakonov hardness coefficient (f) ranging from 6 to 15, bridging the gap between standard PDC bits and more aggressive hard rock tools .
• Rugged Construction with High-Pressure Tolerance: Built to withstand rigorous industrial conditions with a pressure capacity of up to 70 MPa. The high-strength steel body and reinforced cutting structure ensure reliable performance in deep-hole drilling projects, meeting the demands of both commercial mining operations and infrastructure construction .
