Tricone bit is an important tool for oil drilling. Its working performance directly affects drilling quality, drilling efficiency and drilling cost. Roller bit: It can be divided into single cone, double cone, tri cone and multi cone bits according to the number of cutter. Tricone bit is the most commonly used bit at home and abroad.Our products are mainly used in: oil drilling, water well, natural gas drilling, geothermal well drilling, air conditioning well drilling, coal mine exploration, mining, bridge construction, etc.We have a complete range of products including DTH bits, tricone bits, PDC drill bits, impregnated diamond coring bits, water well bits, oil bits, mine bits, drill pipes, drilling rigs and drilling tools. Welcome new and old customers to negotiate cooperation.
Cutting structure
Steel Tooth: Premium tungsten carbide hard facing on the surface, greatly enhance the wear resistance of the tooth.
Tungsten Carbide Inserts: Various type high quality tungsten carbide inserts can be equipped on the bits, professional and scientific selection of the inserts as per the different application and drilling process to achieve high efficient drilling production.
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.
Bearing structure
Journal bearing and roller bearing types are available to be chosen. Abrasion & seizure resistance, loading capacity, stability of the bearing are well improved, suitable for high speed rotary drilling.
Seals and lubrication
The advanced metal seals improve the reliability and stability of the bearing sealing. Pressure difference type compensating system assures a good greasing lubrication function.
IADC
vary from 114--637 applicable for the hole drilling in the upper section with good drillability.
