Tricone Drill Roller Cone Bit
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.

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 featuring :
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.
