Our Company

Hunan Tianying Drilling Machine Manufacturing Co., Ltd is a professional Rock Drilling Bits manufacture, we supplies series of TCI Tricone bits for drilling in soft formation to very hard formation, available in both open-air bearing type or sealed bearing type. Under our R&D team’s constant product development, our Rotary Rock Drilling Bits are renowned for their great reliability, excellent and even quality and long services life with an expertise direct to any corner of the world.All bits the above are manufactured according to strict standards, set forth by the American Petroleum Institute (API). And classified according to characteristics set forth by the International Association of Drilling Contractors (IADC).

This Series Of Rock Roller Bits Can Apply For Drilling Hard To Very-Hard Formation.
Application : For use in abrasive consolidated formations with compressive strength above 400 Mpa such as taconite, quartzite and banded iron formations
Cutting structure: These bits are characterized by closely spaced conical or spherical inserts with medium to low projection. This configuration promotes good penetration rates in hard, consolidated and very abrasive formations. Smaller carbide inserts are provided on the gage and inner rows or hard metal is deposited in the nose area to contain shell erosion and improve performance.

• Compression Strength: 60,000 – 100,000 psi
• Drilling Speeds: 50 – 90 rpm
• Jet Circulation: All sizes
• Weight on Bit (WOB): 4,000 – 7,500 lbs/in of bit diamete

What is Tricone Drill Bit ?

1. A roller cone or tricone rock bit consists of a bit body with three moveable conical rollers equipped with cemented carbide inserts.
2. The idea is the crush the rock by rolling the inserts against the rock with appropriate rotation speed and feed force.
3. 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.
4. Roller bits for hard and abrasive rock generally have spherical cemented carbide inserts closely spaced.
5. Roller bits for softer rock may have the chisel and conical carbide teeth or quality milled steel teeth as the cutters.
6. Three types of cemented carbide inserts are used for roller type bits being Chisel, Conical, and Hemispherical.
7. A roller bit will utilize nozzles from which the compressed air escapes to lift the cuttings from the bottom of the hole.

CUTTING SELECTION GUIDE

Advantage:

1. Optimized cutting structure and bearing geometry to distribute load .
2. More uniformly distributed load over bearings.
3. Smoother bit performance .
4. Sustained penetration rate over longer periods of time .
5. Reduced risk of bearing failure .
6. Streamlined lug manages.
7. larger drill cuttings.
8. Higher penetration rate Less regrinding of cuttings to smaller pieces.
9. Less bit wear.
10. Full body armor minimizes wear on bit body and shirttail.
