Tricone Drilling Bit 6 1/4Inch Rock Drilling Tools Roller Cone Bit Mining Drill Bit

Tricone roller cone drill bit is a critical cutting tool primarily used in rotary drilling applications, especially in oil and gas exploration, mining, and geological surveying.

Normal IADC:
437 Soft Formation TCI Tricone Bits:
The 437 TCI bits are used to drill low compressive strength, very soft formations. TCI bits maximize the use of both conical and chisel tungsten carbide inserts of large diameters and high projection. This cutting structure design, combined with maximum cone offset, results in high bit penetration rates. The deep intermesh of cutter rows prevents bit bailing in sticky formations.
517Medium Formation TCI Tricone Bits:
The 517 features aggressive chisel tungsten carbide inserts on the heel rows and inner rows. This design provides a fast drilling rate and added cutting structure durability in medium-to-medium hard formation. The HSN rubber O-ring provides adequate sealing for bearing durability.
637Hard Formation TCI Tricone Bits:
The 637 bits can be used to drill hard and abrasive formation. Wear-resistant tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge. Maximum numbers of hemispherical-shaped inserts are used in all rows to provide cutter durability and long life.
617Medium-Hard Formation TCI Tricone Bits:
The 617 features robust chisel tungsten carbide inserts on the heel row and conical on the inner rows. This design provides a fast drilling rate and added cutting structure durability in medium to medium hard formations. The HSN rubber O-ring provides adequate sealing for bearing durability.

If you need, please contact us without hesitation, we will give you a satisfactory answer within 24 hours.

Oil and Gas Exploration:
Roller cone bits are extensively used in drilling petroleum and natural gas wells. They excel in crushing and fracturing diverse rock types—from soft shale and sandstone to hard limestone and dolomite—enabling efficient wellbore creation for extraction and production.

Mining and Mineral Exploration:
These bits facilitate core sampling and blast hole drilling in mining operations. They are ideal for excavating mineral deposits, coal seams, and ore bodies, providing precise cutting performance in both surface and underground mining environments.
