Portable hydraulic machine for shearing metals, essentially characterized by comprising an operating head provided with two cutting blades mounted on the corresponding ends of an articulated jaws whose opposite ends are conjugated with links or levers whose angle they form can vary more or less according to the advances and retreats of a piston that is driven by the pressure of a fluid that, through a flexible conduit is driven by a motor-pump group, prior to the passage of the same fluid through a valve, to the position from which it can establish the direct passage of the pressurized fluid to the operating piston or to a feeder tank, in an inactive closed circuit.
