What Is Tricone Drill Bit?

    Roller Cone Bits have conical cutters or cones with steel tooth or tungsten carbide buttons around them.As the drill string is rotated,the bit cones roll along the bottom of the borehole in a circular motion.As they roll,new teeth come in contact with the bottom of the hole,chipping the formation below and around the bit tooth.Air or drilling fluid life the crushed rock chips from the bottom of the hole and up the annulus. As rotation continues,another tooth makes contact with the bottom of the hole and creates new rock chips,thus,the process is continuous.Premium tungsten carbide insert (TCI) bits and milled tooth (MT) bits are needed to be designed to withstand high temperatures and endure long running times while drilling through soft to ultra hard formations.

   Tricone Drill Bit is an ideal solution from soft to 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.The medium formation TCI tricone bits features aggressive chisel tungsten carbide inserts on the heel rows and inner rows. This design provides a fast drilling rate and added cutting structure durability in medium to medium hard for mations. The HSN rubber O-ring provides adequate sealing for bearing durability.
