A method of hot-shearing an elongated metal bar into sections of given gauge length comprises longitudinally indexing the metal bar to position cross-sectional zones thereof where it is to be sheared successively at a plurality of heating stations at which the shear zones of the bar are progressively heated by resistance heating units to reduce the force required for subsequent shearing of the bar through the heated shear zones on ensuing index thereof to a shearing station.
