    17 1/2" IADC 617 Tricone Bit Baker Hughes Tricone Roller Cone Drill Bits For Water Well Drilling


    17 1/2" IADC 617 tricone bit Baker Hughes Tricone Roller Cone Drill Bits for water well drilling


    Tricone Rock Bits provide outstanding performance along with outstanding reliability and simplicity.

    Roschen follows the IADC bit classification system in which the first three digits classify the bit according to the bearing/seal design used and the formation it is designed to drill.

    Tricone bit can be customized to optimize penetration rates and bit life in particular formations and under specific operating weights and rotation speeds. Our company offers new steel tooth and tungsten carbide insert tricone bit in sizes from 3 1/2" – 26", with open or sealed bearings, regular or jet circulation, and a wide range of additional custom features for ideal performance in any formation.


    TRICONE BITS IADC CODE REFERENCE




    First Digit
