1 . Descriptions:
TCI (Tungsten Carbide Insert) bits are utilized for drilling in medium to hard rock formations. These bits feature a range of carbide inserts, such as spherical inserts for extremely hard rock or conical inserts for softer rock. The number of insert rows is determined by the specific application and hole size requirements. Additionally, there are options for open or sealed bearings, as well as three types of shirttail protection. TCI stands for Tungsten Carbide Insert.

4 . Bearing Types
There are primarily three types of bearing designs used in tricone drilling bits:
• STANDARD OPEN BEARING ROLLER BIT:
On these bits the cones will spin freely. This type of bit has a front row of ball bearings and a back row of roller bearings.
• SEALED BEARING ROLLERS BITS
These bits have an O-Ring seal with a grease reservoir for bearing cooling. The seals acts as a barrier against mud and cuttings to protect the bearings
• JOURNAL BEARING ROLLER BITS
These bits are strictly oil/grease cooled with nose bearings, O-Ring seal and a race for maximum performance.
5. Question :
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.
