摘要： A cutting tool with asymmetric structures on cutting teeth has multiple toothed surfaces. Each of the toothed surfaces has multiple groove structures dividing a side edge of the toothed surface into the cutting teeth. Since the groove structures of the toothed surfaces are arranged in an asymmetric and complementary manner, contact areas between the cutting teeth on the toothed surfaces of the cutting tool and a workpiece are reduced. The cutting teeth on the toothed surfaces of the cutting tool are not worn and broken easily. When the cutting tool is used for cutting hard brittle material, machining quality, accuracy, and efficiency are enhanced.
