    Product Description


    17 1/2 inch IADC637 TCI Tricone Bit

    The tricone drill bit is the most popular drilling bit in the world,it can be widely used for Oil&Gas Drilling,Mining,Water
    Well,Geological Exploration areas.Our tricone bit divideds into metal sealed drill bit and rubber sealed bit.
    1. The C-Center jet can avoid the formation of a ball in the bit, eliminate the fluid area at the bottom of the well, accelerate
    the upward flow of drilling cuttings and improve ROP.
    2. High saturation NBR bearings can reduce sealing pressure and improve sealing reliability.
    3. The G-Gauge protection improves the measuring ability and prolongs the service life of the bit.
    4. Adding a row of teeth between the rear taper and the outflow to trim the borehole and protect the cone.

    (1) Cutting Structure of this series tricone rock bit :
    The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.The
    wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.

    (2) Gauge Structure of this series tricone rock bit :
    Multiple gauge protection with gauge trimmers on heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts
    and hardfacing on the shirttail increases gauge holding capability and bearing life.

    (3)Bearing Structure of this series tricone rock bit :
    High precision bearing with two thrust faces. Balls lock the cone.Hardface heard bearing surface. Cone bearing inlaid with
    friction-reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved and
    suitable for high rotary speed.
