Abstract: The bidirectional sheet metal cutting tool (100) is a cutting tool that performs cuts on webbed material in which a length of cut exceeds a physical dimension of the cutting tool (100), while limiting flexing of the webbed material during a cutting operation. The cutter assembly (140) is configured to ride on a guide track (145), and has upper and lower sections. The upper and lower sections have an offset attachment to each other at an interface, so that the webbed material passes the offset after cutting in an extended bypass cutting operation. An interface between the upper and lower sections has a curved profile, allowing deflection of the webbed material on at least one side of a cutting direction. The cutting tool (100) can be mounted to a sheet metal forming tool as a slitter (500), permitting sequential operations of the metal forming tool.
