Product 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 for mations. The HSN rubber O-ring provides adequate sealing for bearing durability.

Quality Control

In manufacturing, each process goes through an extensive and painstaking testing , quality control is a process that ensures customers receive products free from defects and meet their needs.
1, Raw material selection:To make a good drill bit, it is necessary to select the best material and gate keeping the quality of the material. We purchase the high-quality steel and strictly control the material composition and size, it main includes the detection of the shape, diameter, reamed diameter, length composition, and flaw of the raw material, Tungsten Carbide and Grease are also the best raw materials on the market.Besides, we marked every different piece of materials before transferred to the warehouse.
2, In strict accordance with the ISO9001 international standards for production.
Carefully control every step of the production, complete each of the production process, the production process is including blanking, forging, rough turning, heat treatment,fine turning, quenching, assembling, welding,
painting, then storage. Each working process was full inspected, after the qualification, then move to next working process, which to ensure the 100% qualified rate.
3, Sampling observation, numbered, packing and arrange the shipment.

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.

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.
