Tricone Drill Bits

The Tricone Drill Bits is an important tool for Horizontal Directional Drilling(HDD), and its performance will directly affect drilling quality, drilling efficiency, and drilling cost. The design of Tricone Drill Bits is mostly based on practical experience, combined with trial and error methods, and repeated design and calculation. Therefore, the design accuracy is low, the cycle is long, and it is difficult to improve the design quality. Moreover, only one drill bit can be designed for each calculation, resulting in low efficiency.
Tricone Drill Bits have the functions of impact, crushing, and shearing to break formation rocks during work, so they can adapt to various soft, medium, and hard formations. Especially with the emergence of jet type Tricone Drill Bits and long nozzle Tricone Drill Bits, the drilling speed of Tricone Drill Bits has greatly increased, which is a major revolution in the development history of Tricone Drill Bits. Tricone Drill Bits can be divided into milling tooth (steel tooth) Tricone Drill Bits and inlaid tooth (hard alloy teeth embedded on the roller) Tricone Drill Bits according to the type of teeth.

The working principle of Tricone Drill Bit is very simple. Firstly, the rotation of the rotor drives the roller to rotate, causing the three drilling teeth on the roller to simultaneously contact the rock. At this point, the function of the Tricone Drill Bit is to cut the rock, form rock debris, and discharge it from the borehole. As the drilling deepens, the Tricone Drill Bit will continuously cut down on the rock and discharge it from the borehole, ultimately completing the drilling task.

Tricone Drill Bits is a commonly used rock drilling tool, mainly composed of the main body of the Drill Bit, Rollers, and rotor components. Among them, the main body of the Tricone Drill Bits is the drill bit part on the drill pipe, the Roller is the support and rotation device of the three fixed alloy teeth on the drill bit main body, and the rotor is the power source that drives the roller to rotate through rotation. The structure of Tricone Drill Bits is compact and can efficiently cut different types of rocks.

Tricone Drill Bits has two types: milling teeth and inlaid teeth. Milling teeth are usually used in soft rock and hard soil
Layer, inlaid tooth teeth are suitable for hard rock layers, and the higher the rock hardness, the smoother the matching tooth alloy teeth.

1. Tricone Drill Bits is made up high-strength and high toughness hard alloy teeth, the impact resistance of the teeth is improved and the fracture rate is reduced;
2. The optimized design of tooth design, tooth number, exposed tooth height, and unique alloy tooth shape fully utilizes the cutting ability and cutting speed of the drill bit;
3. With the help of snap ring to lock the tooth wheel, Tricone Drill Bits can withstand high drilling pressure;
4. Welding wear-resistant alloy into the inner hole of the tooth wheel to improve the anti biting ability of the bearing;
5. Tricone Drill Bits is made up fully rubber oil reservoir that can limit pressure difference and prevent drilling fluid from entering the lubrication system provides good lubrication for the bearing system and ensures the normal operation of the “O” – shaped sealing ring, improving the service life of the drill bit;
6. Tricone Drill Bits is made up a new type of lubricating grease that is resistant to high temperatures and low wear has improved the high-temperature resistance of the drill bit sealing lubrication system.
7. ZH Tooling Tricone Drill Bits has high cutting force, capable of cutting various types of rocks.
8. ZH Tooling Tricone Drill Bits has simple structure, easy to operate and maintain.
