TCI Tricone Bits feature :
Tungsten carbide inserts, excel in drilling operations in middle to hard rock formations. These bits offer a variety of carbide inserts, including spherically shaped inserts for very hard rock and conically shaped inserts for softer rock, catering to the diverse hardness levels encountered during drilling endeavors.
The number of insert rows directly correlates with the application type and hole size, ensuring customizable configurations for optimal drilling performance. Operators can choose between open and sealed bearings, along with three shirttail protection options, enhancing durability and performance in challenging drilling conditions.
Bearing Types
There are primarily three types of Open and seal 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.
The tricone feature is that they come with their own passport as below :
- The specification of the cones
- The recommended drilling parameters to get the best performance out of the bit:
- Bit weight
- Rotation speed
- Flushing volume
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.
