10 Inch 254mm 3-Wing PDC Bit

10 Inch 254mm 3-Wing Concave PDC Bit With Side PDC Cutters | Custom Thread Drilling Bit
This 10 inch / 254mm 3-wing concave PDC bit is a upgraded heavy-duty drilling tool independently developed by our factory, specially designed for large-diameter water well, mining, geological and geothermal drilling projects. Different from standard conventional PDC bits, this model adopts a unique full-side PDC cutter protection design . The outer edge of each blade is fully inlaid with high-quality PDC cutters, which effectively protects the bit outer diameter from wear, avoids diameter shrinkage during long-distance drilling, and greatly improves the overall durability and service life of the drill bit.
Built with a classic 3-blade concave centered structure, the bit features low drilling resistance, accurate self-centering performance and straight drilling trajectory. It perfectly solves the problems of hole deviation, bit jamming and unbalanced hole wall in large-diameter drilling operations. Reinforced integral blade body technology enhances impact resistance, making it adaptable to complex formations including clay, sand soil, sandstone, weathered rock and medium-hard mixed rock strata. It is an ideal large-size drilling bit for deep water wells, mine blasting holes and geothermal engineering construction.
This 254mm large-size PDC bit supports flexible thread customization to meet diverse rig matching demands. It can be configured with internal thread and external thread of multiple international standard specifications, including API, REG and NC threads. Whether for new drilling equipment matching or old equipment replacement, it can achieve perfect compatibility, solving the problem of single connection mode of traditional drill bits.
As a professional PDC bit manufacturer, we provide factory direct sales, strict quality inspection, and customized processing services according to customer drawings and parameters. The upgraded side PDC protection structure makes this 10-inch drill bit far superior to ordinary products in terms of wear resistance, hole forming accuracy and long-term working stability. It is widely exported to South America, Australia, Poland, Japan, Southeast Asia, Africa, Russia and other regions, winning long-term trust from global drilling engineering contractors and mining enterprises.
