The turret body is provided with indexing means for indexing the tool spindle, and clamping means for clamping the tool spindle at an indexed position indexed by the indexing means. The turret body has a function for indexing the tool spindle for attaching the complex tool thereto and a function for clamping, thereby using the complex tool in a turret lathe.

Turret for turret lathe

A tool holder for attaching a complex tool having a plurality of kinds of cutting edges to a turret, has a base portion attachably and detachably formed at the turret. The base portion has a rotatable tool spindle attachably and detachably installing the complex tool thereon. The tool spindle is provided with indexing means for indexably rotating the tool spindle at an indexed position corresponding to each cutting edge of the complex tool. And, clamping means for clamping the tool spindle at a predetermined indexed position is provided.
