As one of the trusted tricone bit manufacturers with over 10 years of experience, we provide durable and precision-engineered drill bits designed for various drilling applications.
Our tricone bit for sale features three rotating cones with either milled steel teeth for soft formations or tungsten carbide inserts (TCI) for hard formations, ensuring efficient penetration, reduced wear, and extended service life.
Backed by ISO and API certifications, we offer customized solutions and a one-stop procurement service to meet diverse drilling needs.
A Tricone Drill Bit operates using three rotating cone-shaped cutters, each embedded with milled steel teeth or tungsten carbide inserts (TCI). These cones rotate independently as the bit is pressed against the rock, effectively crushing, grinding, and chipping through formations.
Working Mechanism:
Rotation & Weight on Bit (WOB) – The drill string applies downward force, pressing the three cones against the rock surface.
Cone Rotation & Rock Fragmentation – As the drill rotates, the cones roll across the formation, breaking rock through a combination of crushing and shearing actions.
Cutting Efficiency Based on Teeth Design:
Milled Steel Teeth (MT) – Ideal for soft formations, where aggressive cutting is needed.
Tungsten Carbide Inserts (TCI) – Used for hard formations, offering durability and wear resistance.
Mud Circulation & Cooling – Drilling fluid is pumped through nozzles in the bit, cooling the cutters and flushing rock cuttings away to prevent clogging.
