PROBLEM TO BE SOLVED: To provide a billet cutting device capable of highly maintaining cutting performance by making wear of a guide mechanism difficult to generate and allowing replacement on a line and adjustment in operation. SOLUTION: This device is provided with fixed blade 2 and movable blade 4 for cutting a long-sized metal bar as the billet, a hydraulic cylinder 3 mounted with the movable blade 4 on a piston rod 3b, a frame 1 fixed with the fixed blade 2 and the hydraulic cylinder 3, and the guide mechanism of the movable blade 4. The guide mechanism is constituted of a fixed guide 10 provided around a guide hole 5 formed on the frame 1 and outside the frame 1, and a sliding guide 20 passing through the guide hole 5 of the frame 1 to be mounted to project the outside. A gap adjusting means sliding in the relation to the fixed guide 10 and using shims 14 and 15 for the sliding guide 20 and (or) the fixed guide 10 is mounted on the sliding guide 20.
