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.

All advantage extend bit work life
The tricone drill bit is the most popular drilling bit in the world,it can be widely used for Oil&Gas Drilling,Mining,Water Well,Geological Exploration areas.Our tricone bit divideds into metal sealed drill bit and rubber sealed bit.
1. The C-Center jet can avoid the formation of a ball in the bit, eliminate the fluid area at the bottom of the well, accelerate the upward flow of drilling cuttings and improve ROP.
2. High saturation NBR bearings can reduce sealing pressure and improve sealing reliability.
3. The G-Gauge protection improves the measuring ability and prolongs the service life of the bit.
4. Adding a row of teeth between the rear taper and the outflow to trim the borehole and protect the cone.
