8 Inch Tricone Bit On Hard Rock For DTH And Water well drilling
Application
Tricone bits consist of three “cones” which must all rotate on lubricated bearings. This lubrication in turn requires a grease reservoir and for any medium or large scale project some sort of bearing seal to prevent debris from entering the tricone and stopping rotation.
The TriCone Bit is the most versatile drill bit on the market. It is the go to drill bit in most styles of drilling. Whether you are drilling a water well or an oil well, Western Drilling Tools has the Tri Cone Drill Bit for you.
The Advantages of Using a Tri Cone Over Other Drill Bits
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, Western Drilling can provide you
with new, re-run or premium oil field quality Tricone bits. The
difference between a premium oil field Tricone bit and non-premium
oil well quality Tricone is that the roller cones have high end
sealed bearings; 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 Western Drilling to specify a bit that out performs your expectations.
Characteristics
1. The strength and wear resistance of inserts are improve by using
carbide inserts with high strength and high wear resistance.
2. 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.
3. The service life of the bearing is further extended by adopting
harder and more wear resistant material for thrust bearing.
4. This series oil well 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.
5. Thrust bearing surfaces are hard faced and treated with friction
reducing technology.
6. Rotary drill bits use journal bearing. Hard faced head bearing
surface. Cone bearing inlaid with friction reducing alloy and then
silver-plated. The load capacity and seizure resistance of the
bearing is greatly improve.
