A beautifully made set of high speed woodruff key cutters comes in a handsome wood storage base. Woodruff cutters are used for milling (cutting or shaping) woodruff key slots in metal materials. Woodruff key slots are a pocket intended to accommodate a key - an element used to connect a rotating machine element to a shaft. The whole system is called a keyed joint.
