Rock Drill Bit 17-1/2" Tricone Drill Bit of water /oil / Mining Well Drilling Tool
1 . Descriptions:
Tungsten Carbide Insert (TCI) bits serve as indispensable tools for drilling operations in middle to hard rock formations, presenting a versatile range of carbide inserts meticulously designed to address the varying hardness levels of rock encountered during drilling endeavors. These inserts come in diverse shapes, including spherically shaped inserts tailored for exceptionally hard rock formations and conically shaped inserts optimized for softer rock materials.
The selection of carbide inserts plays a pivotal role in determining the efficiency and effectiveness of the drilling process, as different rock formations demand specific insert configurations to achieve optimal results. The number of rows of inserts featured on TCI bits is directly correlated with the nature of the application and the desired hole size, allowing for customizable configurations that cater to specific drilling requirements.

2. Specification:
TCI (Tungsten Carbide Insert) and Steel Tooth Tricone Bits. Each
type is uniquely designed to tackle specific drilling challenges
and geological formations with precision and efficiency.
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.
Steel Tooth Tricone Bits feature :
Steel Tooth Tricone Bit are renowned for their effectiveness in
drilling applications across a spectrum of geological formations.
These bits are particularly well-suited for drilling in shale
formations, soft limestone sites, fast drilling in various strata,
natural gas drilling, deep wells, and abrasive formations.

3 . Tricone Bit profile and Compostition
4 . 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.
5. What we should be pay attention on choosing the tricone drill bit ?
6. The tricone feature is that they come with their own passport as below :
7.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.
