A coiler drum of a reversing rolling mill includes a work portion that engages a strip of metal being processed in the reversing rolling mill. The work portion includes an inner base surface and engaging strips that extend radially outward from the base surface. When the metal strip is engaged by the work portion, the metal strip does not contact the inner base surface, which has a surface area greater than 35 percent of the work surface. The engaging strips can be formed on the coiler drum by using weld overlays, inserts into slots, or by casting the engaging strips onto the coiler drum at the time the coiler drum is cast. The engaging strips may be laterally offset from one another and have a length less than 50 percent of the axial length of the work portion. The engaging strips may also be formed from a different material than the material of the work surface of the coiler drum.
