[0001] The utility model relates to the technical field of resin cutting blades, in particular to an explosion-proof resin cutting blade with high heat dissipation. Background Art

[0002] Resin cutting blades use resin as a binder and glass fiber mesh as a reinforcement. They are made of a variety of materials and have particularly good cutting performance for difficult-to-cut materials such as alloy steel and stainless steel.

[0003] During the cutting process of an object, the resin cutting blade will generate a high temperature due to the friction between the resin cutting blade and the object, which will cause the resin cutting blade to melt or break. Common resin cutting blades on the market usually only have a simple cutting function and cannot achieve a rapid heat dissipation effect on the cutting blade, thereby reducing the service life of the resin cutting blade. In view of this, a high heat dissipation explosion-proof resin cutting blade is proposed to solve the above problem. Utility Model Content
