An annular thread-whirling head is disclosed, wherein, projecting over its periphery, indexable inserts are mounted in recesses in a first plane and are connected directly to the thread-whirling head. The plurality of indexable inserts lies with an indexable insert surface on a bearing surface of the recess, in a manner such that the indexable inserts are individually accessible, and may be assembled and disassembled in a simple manner by way of a fastening element. The produced swarf per indexable insert is minimized by way of the plurality of used indexable inserts, and the service life or the performance of the thread-whirling head is increased. Recesses may also be provided in a second plane so that, apart from a plurality of indexable inserts in a first plane, one may also arrange and fix a plurality of indexable inserts in a second plane, offset parallel to the first plane. A thread-whirling head with indexable inserts in a first and a second plane permits the manufacture of multiplex outer threads in one passage.
