Abstract
Thread-cutting apparatus includes an indexable insert having multiple thread-cutting profiles. The invention may be embodied either in a thread-milling insert or a thread-chasing insert. The insert is configured to provide clearance for internal threading and to enable cutting force to be directed through a large cross-sectional area of the insert.
