In various mining or exploration industries, the drill bits used are all consumable production tools. The quality and life of the drill bit determine the work efficiency and operating cost of the drill. In 1960, wire rope percussion drills were mainly used in mining operations in our country. The drilling technology was relatively backward. This situation directly affected the speed of our country’s construction of the four modernizations. Therefore, increasing the service life of the drill bit is a major factor. Very important thing.

　　Since 1990, my country has continuously expanded its scale and accelerated development in mine production, energy development, and national infrastructure construction. This has put forward higher requirements for the production of drill bits.

　　Our country's drill bit R&D and manufacturing personnel have finally made a very significant breakthrough in each of them after years of struggle. The drill bit production standards and technology are in line with international standards. In addition to meeting domestic industrial production needs, they have also been exported to foreign countries. It has also cultivated a group of scientific research teams with combat effectiveness and a group of production forces who are very proficient in product manufacturing and production management. The successful scientific research of the drill bit has made an important contribution to the development of my country's industry and played a vital role in the construction of the country.

　　At present, China’s four modernizations and further reforms and opening up are developing in a deeper and farther direction. The Chinese government and people hope that China’s scientific and technological forces will be stronger and the industrial development will be faster. As the saying goes: " Workers must first sharpen their tools if they want to do their jobs well.” Only by further popularizing and improving scientific knowledge can reasonable production and use of drill bits and tools be carried out. The development of industry is one of the important signs of social civilization.
