API Water Well Drilling Tools 8 Inch TCI Tricone Bit Steel Tricone Bits
Application
There is a Tri Cone suitable for any rock formation
Tricone bit is versatile and can handle changing formations
Tri Cones are reasonably priced, long lasting and have an efficient drilling rate
Depending on your application, JCDRILL can provide you with new,extremely high quality tungsten carbide and diamond gauge protection throughout the drill bit as well as skirt tail hard facing and optimized hydraulics. These roller cone drill bits are designed to go to extreme depths in extreme conditions and in situations where they cannot fail.
When ordering a bit the IADC bit classification system is a very useful tool and allows JCDRILL specify a bit that out performs your expectations.
The TCI Tricone Bit ranges in size from 3.875” (88.9mm) to 28” (711.2mm)
The Tooth TriCone Bit ranges in size from 5” (127mm to 32” (812.8mm)
Characteristics
1. The tricone roller bit working life is according the drilling formation and the drilling rig.
2. Rock formation: Very soft with low compressive strength and high drillability, such as shale, clay, sandstone and conglomerate, etc.
3. Journal bearing. Hard faced bearing surface. Inner hole of cone is silver-plated. The load capacity and seizure resistance of the bearing is greatly improved.
4. O ring seal is made of the more wear resistant and high saturated buna-N with the increased seal section and precisely designed scaling flange in the cone sealing area has increased the reliability of the seal.
5. All rubber compensator is used which can limit pressure differential and prevent drilling fluid from entering the lubrication system and this provides the bearing system with good assurance of lubrication.
