Abstract: Disposable cutting blades and method for producing disposable cutting blades with profiled cross sections for a device for chipping wood. The method includes heating a primary material of a hardenable material in a soft-annealed state having a worked surface to a temperature above room temperature, but below a conversion temperature Ac1, rolling the primary material to form a profile blank with at least one precisely gaged guide path in a base body in cross section and with an increased thickness of at least one edge region, a metal-removing working of at least one edge region in a longitudinal direction of the profile blank to form a cutting edge and to form scratching edges in a spaced manner directed perpendicularly to the cutting edge, and continuously hardening the edge regions of the cutting blade.

Abstract: A composite tool comprising a supporting part of a metallic material having a first composition and a working part of a metallic material having a second composition which is different from the first composition, a process for the manufacture thereof and a method of cutting an austentic alloy article with this composite tool. The supporting part of the composite tool is made of a tenacious iron-based material, and the working part is made of a precipitation harden iron-cobalt-tungsten alloy. The parts are joined by a metallic connection.

Abstract: The invention relates to a process for producing a cutting tool, in particular saws, cutting rules or cutting dies, comprising a carrier material (1) in strip or disk form, to whose edge, which is substantially standing on end, a cutting-edge region (2) in the form of a pulverulent alloy is applied and melted during the application, preferably by means of a laser beam, and then solidifies on the edge.

Abstract: The invention relates to a composite tool consisting of a metallic supporting part and at least one such working part of different material compositions, which parts are metallically bonded to each other, in particular, a saw blade or bandsaw. For increasing the cutting yield and tool service life, in particular, when working titanium and titanium alloys, austenitic Cr—Ni—Mn—N steels and nickel and nickel-based alloys, the invention provides that the supporting part or the supporting strip are formed of a tenacious iron-based material and that the working part(s) are formed of a precipitation hardenable iron-cobalt-tungsten alloy (Fe—Co—W).
