[0002] Cutting tools are tools used for cutting processing in mechanical manufacturing. Most of the tools are machine-used, but there are also hand-used tools. Since the tools used in mechanical manufacturing are basically used to cut metal materials, the term "tool" is generally understood to refer to metal cutting tools. Cutting tools are needed for gear arc chamfering.

[0004] However, there are some problems with the existing technology: during the use of existing metal cutting tools, the long-term cutting friction between the tool and the gear surface generates a large amount of heat that accumulates inside the cutter head. The coolant sprayed on its surface can only take away a limited amount of heat, which makes the tool easily damaged under long-term high temperature, affecting the service life of the tool. When a chip appears on the blade, the cutting effect is affected during the metal cutting process, and the tool needs to be replaced, which is time-consuming and labor-intensive. Therefore, we propose a textured structure metal cutting tool. Utility Model Content
