TANK IADC 117, 127, 137, and 217 steel tooth tricone bits are designed for drilling soft rock formations where high penetration rate and efficient drilling performance are required.
These steel tooth roller cone drill bits feature aggressive milled tooth cutting structures that enable rapid drilling in formations with high drillability. The cutting teeth are reinforced with advanced hardfacing technology to improve wear resistance and extend bit life.
The optimized tooth geometry allows efficient drilling in formations such as limestone, soft shale, soft marble, clay, and other soft sedimentary formations.
These tricone drill bits are widely used in water well drilling, oilfield drilling, geothermal drilling, and mining exploration, providing high drilling speed and reduced drilling cost per meter.
