Technical Field

[0001] The utility model relates to the technical field of machining tools, in particular to a machining tool capable of avoiding breakage. Background Art

[0002] Machining tools are tools used for cutting, milling, drilling and other machining operations. Common machining tools include drills, milling cutters, turning tools, blades, etc. These tools are usually made of materials such as cemented carbide and high-speed steel, and have a certain hardness and wear resistance to ensure that the material can be effectively cut during the machining process. In the machining process, the correct selection and use of machining tools is crucial to improving machining efficiency and quality.

[0003] Most existing blades are installed by fixing the blade to the cutter head by bolts. The blade fits closely with the cutter head, and the tool will vibrate during cutting.
