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.
1.Compression Strength: 20,000 – 70,000 psi
2.Drilling Speeds: 60 – 100 rpm
3.Jet Circulation: All sizes
4.Weight on Bit (WOB): 2,500 – 7,000 lbs/in of bit diameterat
Bits thread are manufactured according to API standards.

Products Description
What Is Tricone Drill Bit?
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 formations. The HSN rubber O-ring provides adequate sealing for bearing durability.

Working principle
1) Revolution of drill bit The revolution speed of the drill bit is the rotation speed of the turntable or the
down hole power drilling tool. When the drill bit revolves, the cone also rotates around the axis of the drill bit. The linear
speed of each row of teeth on the cone rotating around the axis of the drill bit is different, and the linear speed of the outer
row of teeth is the largest.

speed of each row of teeth on the cone rotating around the axis of the drill bit is different, and the linear speed of the outer
row of teeth is the largest.
2) Rotation of the drill bit When the drill bit rotates, the counterclockwise rotation of the cone
around the axis of the tooth palm is called auto rotation. The rotation speed of the cone is determined by the revolution speed of the drill bit, and is related to the effect of the teeth on the bottom of the well.
3) Longitudinal vibration (axial vibration) impact crushing of the drill bit The change of the position of the wheel center makes the drill bit reciprocate up and down along the axial direction, which is the longitudinal vibration of the drill bit, which is related to the drill bit structure parameters such as tooth height and tooth spacing and lithology. Soft strata have small amplitudes, while hard strata have large amplitudes. The vibration frequency is proportional to the number of teeth and the speed of the cone.
4) Sliding shear breaking action of drill bit Crushing different types of rock requires different slippage of the drill bit, which
is determined by the structural parameters of the drill bit. In soft formations, bit slippage is large, and in hard formations, it
should be as small as possible or not slipped.
