[0002] Cutting tools are tools used for cutting processes in mechanical manufacturing. They are divided into metal cutting tools, woodworking tools, and mining tools, etc. Machining tools are mainly used for metal cutting, and common types include turning tools, milling cutters, drills, boring tools, and reamers.

[0003] During workpiece processing, different processing operations are sometimes required, such as milling, grinding, etc., which require changing different cutting heads. In order to improve processing efficiency and reduce the time spent changing tools, there are also multi-functional cutting tools on the market.
