Cemented carbide precision tools are based on excellent matrix technology, grinding technology and coating technology. They have the characteristics of high efficiency, high speed, high precision, and long life. The product categories mainly include insert, end mill, and cutting tools for 3C (computer, communications, and electronic consumer goods) and PCB (printed circuit board) machining. Cemented carbide precision tools meet the needs of high-end manufacturing industries such as aircraft, automobiles, shipbuilding, and 3C. According to statistics, the global market for cutting tools has reached 10 billion US dollars. In this paper, the resource advantages, processing advantages and performance advantages of Ti（CxN1-x）based cermet are introduced, the technical limitations of Ti（CxN1-x）based cermet is analyzed, and the development of Ti for the domestic application status of Xiamen Tungsten R&D is introduced. Based on the research on Ti（CxN1-x） based cermet tools, the future of the market is prospected. At present, Ti（CxN1-x） based cermets account for about 1/5 to 1/4 of the cutting tool materials in developed countries, and Japan has reached 1/3. The use of Ti（CxN1-x） based cermets is still increasing year by year. The demand for cermet indexable tools will account for 50% of the total in the future. According to this calculation, in the next 10 years, Chinese cermet cutting tools will form a market scale of 5 to 6 billion yuan.
