PURPOSE: An automatic cutting device for hard metal bar materials is provided to reduce the cutting time of a bar material since a hard metal bar material is cut into multiple materials having short length. CONSTITUTION: An automatic cutting device for hard metal bar materials comprises multiple circular cutting blades(4), a hydraulic controller(24), push rods, a material discharging cylinder(63), and a material piece ejecting unit(65). The circular cutting blades slowly moves down with the hydraulic controller and cut a hard metal bar material(P) into multiple pieces. After completion of the material cutting process, the push rods are turned upward. The material discharging cylinder is operated, the piston rod is moved back, a rotary shaft(61) is rotated counter clock-wise with a plain gear(62), and a material support tool(6) is rotated. Accordingly, piece bar materials on the material support tool are poured out on the material piece ejecting unit.
