PRODUCT DESCRIPTION
TCI 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.
>> Characteristics
The tricone drill bit is the most popular drill bit in the world, it can be widely used for oil&gas drilling, mining, water well, geological exploration areas.Our tricone drill bit is divided into metal sealed drill bit and rubber sealed drill bit.
>> The C-centre jet can avoid the formation of a ball in the bit, eliminate the fluid area at the bottom of the hole, accelerate the upward flow of cuttings and improve the ROP.
>> High saturation NBR bearings can reduce sealing pressure and improve sealing reliability.
>>Gauge protection improves gaugeability and extends bit life.
>>Add a row of teeth between the rear taper and the outlet to trim the hole and protect the taper.
