[0002] Circular saw blade is a general term for a circular blade tool used to cut solid materials. Its edge is endowed with sharp teeth, which can grab the workpiece under high-speed rotation and produce a cutting effect. Depending on the cutting object, saw blades of different materials are required, such as diamond saw blades for stone cutting, high-speed steel saw blades for metal material cutting, and carbide saw blades for cutting solid wood, artificial boards, aluminum profiles, plastics, plastic steel, etc.

[0003] Circular saw blades are highly efficient tools widely used in metallurgy, machinery, stone processing and other industries. At present, the saw blades produced in my country mainly adopt non-embedded welding method, that is, the carbide saw teeth, also known as the cutter head, are directly welded to the outside of the toothed disc. After welding, the impact resistance of the cutter head is greatly reduced, and it is easy to break and fall off teeth. Therefore, a double-head saw blade with positive and negative cutting is proposed to solve the above problems. Utility Model Content
