Rock Drilling Bit 12-1/4 " Tricone Drill Bit of oil Well Bit
1 . Descriptions:
Tungsten Carbide Insert (TCI) bits are are used middle to hard rock formation which offers a variety of carbide inserts such as spherically shaped inserts for very hard rock or conically shaped inserts for softer rock. The number of rows of inserts is directly related to the type of application and the size of hole to be drilled. here are also open and sealed bearings available as well as three types of shirttail protection to choose from. TCI stands for Tungsten Carbide Insert.

3 . Roller Cone Bit Profile
The Tricone Bit is composed by Tricone bits consist of three rotating cones that have teeth made of a hard material, usually steel, tungsten carbide, or diamond.
These teeth crush the rock as the cones rotate, and the rock debris is then cleared away by the drilling fluid
4. What we should be pay attention on choosing the tricone drill bit ?
The tricone feature is that they come with their own passport as below :
Which type of tricone you should choose ?
It depends on the geology you are drilling in and the diameters of the borehole you are drilling. The International Association of Drilling Contractors (IADC) have developed an easy use step system to choose the right tricone for your geology with additional features such as bit protection for longer production life.
