[0002] There are many types of diamond coated tools with significant performance differences. The structures, preparation methods and application fields of different types of diamond tools are quite different. Diamond coated milling cutters have the advantages of 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. In addition, diamond is a pure crystal without adhesive. Compared with single crystal diamond, it has the same properties. The excellent coating technology greatly improves the cutting performance and service life of the milling blade.

[0003] In the prior art, a diamond-coated milling cutter with an adjustable function and a publication number of CN218425842U includes a drill rod, one end of which is provided with a connection block.
