Among all detailed classifications, cutting tools are the most widely used scene of cemented carbide, accounting for 33%. In view of the fact that cemented carbide itself has the advantages of high hardness, wear resistance and red hardness, high strength and elastic modulus, good corrosion resistance and oxidation resistance, small linear expansion coefficient, and no longer processing and regrinding of molded products, so hard Alloy cutting tools have become the most widely used "industrial teeth", and they are also widely used in various cutting machine tools. Cemented carbide tools can be classified into cutting inserts (accounting for 49.7%, which is the largest proportion of cemented carbide tools), milling tools (27.6%), and hole processing tools (18%). According to the subsequent processing method, it can be divided into rough machining tool and finishing tool. Among the same alloys, those with more cobalt content are suitable for rough machining, and those with lower cobalt content are suitable for finishing.

In terms of the sales of the more subdivided carbide cutting tool manufacturing industry, the proportion of automobile and motorcycle sales reached 21%, followed by the field of machine tools (18%) and general machinery (15%). For the automotive industry, the main application scenarios of cutting tools are to cut and produce engine cylinder blocks, crankshafts, connecting rods, and parts such as gearboxes, axles, and hubs. The production process of related parts is more complicated, and the division of labor is more detailed. For the general machinery industry, the main application scope of knives includes agricultural machinery, household appliances and sanitary ware, mining machinery, electrical machinery, etc. The materials in the aerospace field are mostly high-performance and difficult-to-machine materials such as titanium alloys, high-temperature alloys, and composite materials. Therefore, there is an urgent need for long-life, high-reliability knives. The Zhuzhou Diamond Co., Ltd. already has benchmark products and put them into mass production, and is waiting to challenge the dominance of overseas high-end brands.
