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.
