API 8 1/2"IADC437 TCI Tricone Roller Bit for Oil Well Drilling
TCI Tricone Bit is the most popular drilling bit in the world which can be widely used for Oil and Gas Drilling,Mining,Water Well,
Geological Exploration areas.

The IADC code from 417 to 837 can meet your difference hard formation drilling.
Also you can tell us the drilling formations,then we can offer professional suggestion for suitable IADC.

Additional Features which you can choose 


G - Gauge Protection

Special carbide inserts are strategically fixed on the back of cones to effectively reduce wear in abrasive formation and directional and horizontal wells and extend the bit life.


C - Center Jet

Center jet can avoid bit balling,eliminate resorting area of fluid at bottom hole,expedition upward flow of cutting and improve ROP.Its suitable for drilling in soft to medium soft formations with low compressive strength and high drill ability.


T - Enhanced Carbide Inserts

The enhanced carbide inserts in heel ,gage rows and head OD can make the bit to work long time and better performance when drilling in more abrasive ,hard and extreme hard formations.


L - Bit Stabilization

The function of bit stabilization is for improving working situation of bit,which can effectively protect head and compensator recess in well drilling.
Carbide Insert Shapes of TCI Tricone Bit
  
K - Hard Formation Cutting Structure
The bit adopts unique design parameters and extended cutting tooth-top to improve the bottom hole crushing volume and bottom hole coverage of the teeth and improve the penetration rate of the bit in the hard formation drilling.

X - Wedge Tooth
The main cutting teeth of the bit are wedge-shaped teeth, which have the characteristics of high cutting efficiency and strong crushing resistance for a specific medium soft to medium hard formation, effectively improving the penetration rate of the bit and making the bit working long time.
 

Y - Conical Insert Shape
The main cutting teeth of the bit are conical teeth,which are suitable for drilling in hard and brittle formation.Usually IADC 637 tricone bit use this shape carbide insert on cones.
