Tricone Drill Bit 12-1/4 Inch Drilling Tool

Description 

A tricone bit is an essential component of the bottom hole assembly used in drilling operations.

This mechanical drill bit utilizes rotational motion and the mechanical friction generated by its teeth to remove the rock surface during drilling. 

Its purpose is to harness the energy from the rotating drill string and the mud supply, effectively applying this force to facilitate well deepening.

Applications

• Geotechnical investigation
• Mining exploration & Probing
• Geotechnical instrumentation
• Geophysics

 
Bearing Types

• 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.
 
 
IADC Codes

First Digit 1, 2, and 3 designate STEEL TOOTH BITS with 1 for soft, 2 for medium and 3 for hard formations.
4, 5, 6, 7 and 8 designate TUNGSTEN CARBIDE INSERT BITS for varying formation hardness with 4 being the softest and 8 the hardest.
 
Second Digit 1, 2, 3 and 4 are further breakdown of formation with 1 being the softest and 4 the hardest.
 
Third Digit This digit will classify the bit according to bearing/ seal type as follows:
