Product Description
Tricone Drill Bit 12-1/2 Inch IADC 537 6 5/8 API Pin
1 . Descriptions:
Tungsten Carbide Insert (TCI) bits are utilized in drilling operations involving medium to hard rock formations.These bits feature a range of carbide inserts, including spherical inserts for extremely hard rock and conical inserts for softer rock.The number of insert rows directly corresponds to the specific application and the size of the hole to be drilled. Additionally, there are options for both open and sealed bearings, as well as three types of shirttail protection to choose from. TCI is an abbreviation 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 ?
- Tricone Bit IADC code passport
- Tricone Bit TCI & Steel tooth options
- Tricone Bit Additional tungsten carbide inserts on heel rows
- Tricone Bit Tungsten carbide coating on cone bodies
- Tricone Bit Diamond coated tungsten carbide inserts on the gauge of the cones
- Tricone Bit Tungsten carbide inserts on the shirttail of the legs
- Tricone Bit Additional central nozzle for cleaning cones
The tricone feature is that they come with their own passport as below :
- The specification of the cones
- The quality stamp signed by the person who made and checked the bit
- 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.
