TANK IADC 537, 617, and 627 tricone bits are engineered for drilling medium-hard rock formations where balanced cutting efficiency and durability are required. These TCI tricone drill bits feature a cutting structure composed of chisel and conical tungsten carbide inserts arranged on the cone rows to deliver efficient rock crushing performance.
The optimized insert layout improves penetration rate and drilling stability when working in formations such as apatite, gabbro, coal seams, silicified magnesite, and other medium-hard abrasive rocks.
To ensure longer service life in demanding drilling conditions, the bit body includes reinforced shirttail protection with tungsten carbide inserts, which significantly enhances wear resistance and protects the bit structure during extended drilling operations.
These roller cone drill bits are widely used in mining drilling, oilfield drilling, geothermal drilling, and water well drilling, providing stable performance and reduced drilling cost per meter.

- Location: West Java, Indonesia
- Formation: Medium-Hard Volcanic Rock
- Bit Type: IADC 617 TCI Tricone Bit
- Hole Size: 8 1/2 inch
- Application: Geothermal Exploration Drilling
Performance Result
The TANK IADC 617 tricone bit delivered stable drilling performance in volcanic formations with high abrasiveness. Compared with the previous bit supplier, the drilling contractor observed:
- 15% higher penetration rate
- Improved wear resistance of carbide inserts
- Longer drilling intervals between bit replacements
Customer Feedback
"The TANK tricone bits performed very well in our geothermal drilling project. The bit life was longer and drilling efficiency improved compared with the previous bits we used."
