Tricone bit is a type of rock drill bit that can be used for drilling soft, medium, and hard formations
How is tricone bit work?
It uses its rolling cutters ( also called three cones) to cut away the surface of the drilled rock. Tricone rock bit is usually fitted onto the end of a drill pipe and rotated against the drill face.
What is tricone bit consist of?
It has three rolling cutters ( also called three cones), which must all rotate on lubricated bearings which ensure smooth rotation under heavy loads. The bearing surfaces are made of tungsten carbide, and the cones are usually steel-made, cone-shaped heads equipped with several rows of concentric teeth. Tricone bits have two types body, one is Milled Teeth Body, which can be used in soft and medium formations, and another is tungsten carbide teeth, which can bite into harder rock formations such as granite and limestone, etc.
What is tricone bits’ application:
Widely used for Water well, Mining, Oil & Gas, Geothermal, Horizontal Directional Drilling (HDD), Blast holes, etc.
Advantage: Tricone bits are also easier to control in extreme situations, providing more options regarding torque and Weight On Bits.
