What Is Tricone Drill Bit?

A roller cone or tricone rock bit consists of a bit body with three moveable conical rollers equipped with cemented carbide inserts.The idea is the crush the rock by rolling the inserts against the rock with appropriate rotation speed and feed force.Carbide inserts are distributed over the three rollers in such a manner that the entire bottom of the hole is worked on when the drill bit is rotated. Roller bits for hard and abrasive rock generally have spherical cemented carbide inserts closely spaced. Roller bits for softer rock may have the chisel and conical carbide teeth or quality milled steel teeth as the cutters.Three types of cemented carbide inserts are used for roller type bits being Chisel, Conical, and Hemispherical.A roller bit will utilize nozzles from which the compressed air escapes to lift the cuttings from the bottom of the hole.

Advantage:

High quality----strictly act according to the ISO9001 standard, and all bits are manufactured according to strict standards, set forth by the American Petroleum Institute (API).

Propessional Equipment---- No matter raw material selection, or processing technology are selected is the industry leading technical equipment.

16 Years History---- From 2003 to 2019, customers are located all over the world and win a good reputation.

Application:

Soft to Medium-Soft Formation

For use in less abrasive softer formations with compressive strength ranging up to 270 Mpa, such as shales, limestones, carbonates and most metamorphic formations.

Cutting structure: These bits are characterized by large diameter, widely spaced chisel or sharp conical inserts with high projection. This configuration promotes maximum penetration rates in softer formations. Smaller carbide inserts are provided on the gage and inner rows to contain shell erosion and improve performance.

• Compression Strength: 15,000-25,000 psi
• Drilling Speeds: 80 – 110 rpm
• Jet Circulation: All sizes
• Weight on Bit (WOB): 2,000 – 5,000 lbs/in of bit diameter
