 The Advantages of Using a Tri Cone Over Other Drill Bits
1)There is a Tri Cone suitable for any rock formation
2) Tricone bit is versatile and can handle changing formations
3)Tri Cones are reasonably priced, long lasting and have an efficient drilling rate
4)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.
