    Tricone Bits

    Tricone rotary bits are sometimes a good alternative to a DTH hammer. Available in TCI (carbide buttons) and mill tooth configurations.

    We carry a large inventory of rerun bits and can also supply new bits. TCI bits are available for Medium Soft, Medium Hard, and Hard formations. Please call us to check stock.

    Remember, when drilling with Tricone Bits you need to maintain proper down pressure to prevent premature bearing failure.


    Features


    1.Cutting Structure

    The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.


    2.Gauge Structure

    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

    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.


    4.Seal and Lubrication

    The advanced metal seal package consists of two metal seats and two elastic energizers. Compressed energizers ensure good contact being kept on two sealing surfaces of metal rings by elastic force, and achieve the bearing seal. In the drilling, metal seal are relatively dynamic, and the energizers are static. This will improve the reliability and durability of bearing seal. The pressure compensator system and advanced grease can greatly increase the lubricating reliability.
