The present invention provides a combined splitting blade, including a cutting ring and a fixed disc. The cutting ring is provided with a through-hole for the flange and a blade formed on the periphery. The fixed disc is partially covered on the upper and lower end surfaces around the through-hole of the cutting ring by die-casting. The cutting ring is clamped tightly. The fixed disc and the cutting ring are made of different materials. As the cutting ring and fixed disc are not prefabricated nor made of the same kind of materials, thus simplifying the fabrication process of the blade to save the cost of materials, processing and fabrication time. In addition, the combined splitting blade is fabricated by of rolling.
