Tapered drilling tools currently have a low range of applications in some fields of excavation and drilling, but in terms of performance, their future development trend is very good, and the use-value is high, especially for some deep wells and high hardness rocks. For complex geological conditions, this kind of drill bit is undoubtedly excellent. Therefore, the prospect of tapered drilling tools in the future is very broad. Of course, the technology still needs certain development to mature.

　　So what is the reason that restricts the development of tapered drilling tools? First of all, it is indeed defective in some aspects, for example, the drilling speed is low and cannot meet certain requirements, resulting in low current use value. This is the most common phenomenon in current equipment. The reason for this is insufficient water power and insufficient mechanical braking power.

　　Of course, some domestic tapered drilling tools companies does not give up research on their performance. A lot of drill bits have been developed and there have been great breakthroughs in technology. After years of development, a variety of serialized and large-size drill bits and machinery have been developed, which are fully suitable for large-size drilling and can achieve higher speeds.

　　tapered drilling tools have good advantages and characteristics in many aspects, and have a high development space in mechanical crushing work, which can meet the digging ability of higher hardness rocks; and also have sufficient resistance to fatigue and wear. In terms of cutting teeth, the number of cutting teeth is increased and the size is reduced, which is more conducive to cutting teeth to enter the ground.

　　tapered drilling tools mainly include several parts: bypass valve, hydraulic motor, Cardan shaft, and transmission shaft. The motor mainly provides power and directly affects its speed and load. It is currently the main factor restricting the development of tapered drilling tools in China. However, as the current drill technology continues to mature, its application prospects are becoming more and more extensive.
