A die has first and second apertures(12, 13) extending longitudinally. The flow of the metallic material forced against the entry wall is directed along two neighboring flow paths following first and second entry surfaces(24,26), with the first entry surface directing a first portion of the metallic material past the second aperture and into the first aperture, and with the second entry surface directing a second portion of the metallic material past the first aperture and into the second aperture. The metallic material of the workpiece separates under the influence of cross shear stress through the two apertures.
