A modular rolling mill comprises a plurality of rolling units having work rolls configured and arranged to progressively reduce the cross sectional area of a product received along a mill pass line. Gear units are mechanically coupled to each rolling unit, with each gear unit in turn being mechanically coupled to a driven line shaf t by first bevel gear sets. The ratios of the first bevel gear sets progressively increase fr om the first to the last of the gear units to thereby accommodate a progressively increasing spe ed of the product being rolled. A second bevel gear set is associated with the last ge ar unit. The ratio of the second bevel gear set is the same as the ratio of the first lev el gear set of the penultimate gear unit. The line shaft is selectively coupled to the last gea r unit via one or the other of its first and second bevel gear sets.
