Diamond tools have extremely high hardness and wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity, low thermal expansion coefficient, and low affinity with non-ferrous metals. It can be used for precision processing of non-metallic hard and brittle materials such as graphite, high wear-resistant materials, composite materials, high silicon aluminum alloys and other tough non-ferrous metal materials. There are many types of diamond tools with significant performance differences. The structure, preparation methods and application fields of different types of diamond tools are quite different.

According to statistics from the State Intellectual Property Office, as of March 2010, the number of patent applications received in my country has exceeded 6,011,448. However, among the numerous patent applications, domestic tool companies still lack the number of patent applications. If you enter the company name to search, the comparison results may be even more surprising. Many internationally renowned tool companies have applied for more than 100 patents, among which Sandvik Coromant has registered more than 400 patents.
