-The 437 TCI bits are used to drill low compressive strength, very soft formations. This series rock bit use sealed roller bearing structure. With rollers arranged in grooves recessed in the cone body, the size of the bearing journal is increased.
-Glorytek tricone bits is the service life of the bearing is further extended by adopting harder and more wear resistant material for thrust bearing.
-Surface of the high precision bearing heat treated by using advanced heat treatment process to improve the load capacity and service life of the bearing.
-The strength and wear resistance of inserts are improve by using carbide inserts with high strength and high wear resistance.
>Tricone bits, which some may also call roller cone bits or tri-cone bits, have three cones.
>Each cone can be rotated individually when the drill string rotates the body of the bit.
>The cones have roller bearings fitted at the time of assembly. The rolling cutting bits can be used to drill any formations if the proper cutter, bearing, and nozzle are selected.
