TANK IADC 637 tricone bits are designed for drilling medium-hard to hard rock formations where durability and stable drilling performance are required. These TCI tricone drill bits feature a cutting structure composed of conical tungsten carbide inserts with optimized spacing and small curve radius.
This insert configuration provides excellent rock crushing efficiency and improved penetration rate when drilling formations such as fine-grained basalt, granite, siliceous limestone, and porphyry formations.
To enhance durability during drilling operations, the bit body is equipped with reinforced shirttail protection using tungsten carbide inserts, which significantly improves wear resistance and extends the operational life of the roller cone drill bit in abrasive environments.
These tricone rock bits are widely used in mining drilling, geothermal drilling, oilfield drilling, and water well drilling, providing reliable performance and lower drilling cost per meter.

The TANK IADC 637 tricone drill bit demonstrated excellent drilling stability and wear resistance in medium-hard volcanic formations. Compared with the previously used bit from another supplier, the drilling contractor reported:
• 18% increase in penetration rate
"The IADC 637 tricone bits from TANK delivered stable drilling performance in our basalt formations. The bit life was longer than expected and helped us reduce overall drilling costs."
