Introduction:
TCI Tricone Bit is suitable for soft to hard formation with low compressive strength and high drillability, such as mudstone, gypsum and soft limestone, etc. Tricone bit with high strength toughness of carbide tooth reduces rate of gear broken and with high-performance wear resistant materials improve the wear resistance and service life of the bit.

Application:
water well drilling,oil &gas well drilling ,HDD,exploration,geothermal well drilling,drilling projects,etc.
Hard formations with high compressive strength, such as sandstone, limestone, dolomite ,hard gypsum, marble, etc
Technology:
1. Sealing and Lubrication: The bearing seal uses a top-notch HNBR O-ring for optimal sealing. The exceptional compression and radial seal design enhance the sealing performance. The compensation system and superior grease prevent excessive pressure and greatly improve lubrication reliability.
2. Motor hardfacing: Tungsten carbide particle hardfacing is generously applied on the shirttail and extended to the front of the bit leg to provide extra safeguarding in high-speed, directional, or abrasive conditions.
