In the rapid development of economic construction in contemporary society, the laying and transformation of transportation roads, the survey and development of various mining, the construction and development of the energy field, the demolition and reconstruction of construction infrastructure, and the construction of tapered drilling tools. Broad demand and quality requirements are getting higher and higher.

　　At the same time, due to the continuous improvement of science and technology and the rapid development of the world's industrialization process, rock drilling equipment has been continuously improved and upgraded in non-stop upgrading, and large-scale power rock drilling equipment has also continuously launched new products, coupled with the fierce modern society. Competition makes people's awareness of cost-saving continue to increase, and various industries have put forward more requirements on the performance, variety, and quality of tapered drilling tools products.

　　It is the application and production of tapered drilling tools that play an extremely important role in the process of human development. It is a tool for humans to conquer ores and one of the important means for humans to obtain energy. Without its appearance, there will be no further industrial development. Tapered drilling tools are made up of a more elongated drill rod and an alloy drill bit with higher hardness. In rock drilling operations, tapered drilling tools are constantly subject to wear and corrosion of various pit waters during drilling operations. Tapered drilling tools must withstand various forces such as "tensile force, pressure, bending force, torsion, reaction force, etc." under the high-speed impact of high-power rock drills. The above-mentioned reasons have caused the service life of tapered drilling tools to be very short, usually, only a dozen minutes or the longest can only be used for tens of hours. In the current manufacturing of all steel tools in human society, the technical content of medium drilling tools is very high. How to improve The manufacturing technology of tapered drilling tools has become a very important subject.
