Description

What Is Tricone Drill Bit?

Tricone Drill Bitis 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.

Application:

Medium to Medium-Hard Formation

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 moderately spaced conical inserts with medium projection. This configuration promotes good penetration rates in medium hard and moderately 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.
