What is Tricone Rock Bit ?

Tricone Rock Bit is an ideal solution for soft, medium, or hard rock formations, it is connected with the drill stem and rotates along with it, and drive cones to pressed on the rock. Each cone rotates round the axis of its leg and three cones simultaneously revolve around the bit center. The tungsten carbide inserts on the cone shell cause the formation to spall under the weight on bit and the impact load of cone rotating, the debris will be discharged out to hole by compression air. Tricone bits come in several different varieties, and can deal with a wide range of different rock formations. It is important to know the type of formation you are drilling in when selecting a drill bit.

Hard to Very-Hard Formation

Application : For use in moderately abrasive consolidated formations with compressive strength ranging between 140 – 485 Mpa such as hard limestone, quartzite, granodiorite, and medium grade metamorphic 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

These bits are used to drill high-compressive strength, medium hard formations. A small amount of cone offset and low insert projection is used to prevent cutting structure damage when hard streaks are encountered. Increased numbers of blunter, smaller diameter inserts are used to increase life in harder, more abrasive formations.
