Abstract: The present invention relates to a cast cutter that has upper and lower cutting blade portions each having opposing cutting blades formed at either side of the upper and lower portions thereof in such a way that the opposing cutting blades of the upper cutting blade portion and the opposing cutting blades of the lower cutting blade portion are operated cooperatively with each other, such that the upper and lower cutting blade portions perform a cutting operation, while forming a cutting range of a predetermined width, thereby minimizing a cutting load generated when cutting a cast to make the cutting operation simplified, and thereby having no limitation on a cutting length to provide an excellent cutting efficiency.
