Product Description

Choice of tci roller bit type
1) Formation conditions
2) Previous footage of the tci drill bit
3) tungsten carbide drill bit cost
4) Existing feasible conditions

5) The roller cone bits for make Hole Opener
The choice of tricone bit type has a significant impact on drilling costs.Generally, the softer the type of drill bit,the higher the mechanical speed can be obtained. Because the tooth length, the shifting axis are too large, and the scraping effect is large,the teeth are easily worn and broken. Therefore,it is necessary to select the drill type according to the lithology and the wear of the drill bit.

tci tricone bit for oil drilling well

The Advantages of Using a TriCone
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
