Short answer: Cold drawing pulls a rod, bar or tube through a hardened die (and, for tubes, over a plug) at room temperature, reducing its size while improving surface finish, dimensional accuracy and strength through strain hardening. Bright drawn bar, precision tube and fine wire all come from drawing: it delivers tolerances and a clean, scale-free surface that hot processes cannot, at the cost of reduced ductility that annealing restores when needed.
