This invention is concerned with the production of steel fiber by machining a thick steel plate or block for reinforced concrete, where a milling cutter having a plurality of cutting edges is positioned on the steel plate or block and is moved relatively in the horizontal direction. A surface of said plate or block is machined by the rotating cutting edges to chop steel fibers of approximate triangular in cross section. According to this method, steel fibers of high quality may be economically produced.
