Tricone Drill Bits
Tricone drill bits are traditional rotary drilling tools using tungsten carbide inserts (TCI) or steel teeth, suitable for formations from soft to ultra-hard rock. Diameter range 75-660mm, full IADC series certified.
Product Overview
Tricone drill bits are one of the most commonly used drilling tools in oil, mining and water well drilling. The three-cone structure creates impact and crushing action during rotation, effectively breaking rock. Our tricone drill bits are manufactured by certified partner factories using TCI (Tungsten Carbide Insert) technology, with stronger wear resistance and higher drilling efficiency.
Products are produced by certified partner factories and certified by IADC (International Association of Drilling Contractors), covering the full series from IADC 517 to 737, meeting various drilling needs from ultra-soft to ultra-hard rock formations.
