摘要：
A method for forming a longitudinally extending keyway portion in a mill roll having a central bore, in which the keyway portion may be either a keyway or a tab portion. A cutting head is provided, and includes a body and one or more cutting tools extending from the periphery of the cutting head body. The cutting head is driven through the central bore of the mill roll, and the cutting tools form one or more keyway portions adjacent and communicating with the central bore.
