A bar puller mounted at a tool station on the turret of a numerically controlled turret lathe has opposing reversible, self-centering jaws biased toward each other and to a centered position for general alignment with the projecting end portion of a bar held by a rotary chuck mechanism, which comprises part of the lathe. The jaws receive and grip the projecting end portion of the bar therebetween when the bar puller is forced into engagement with the projecting end of the bar by movement of the turret. The bar puller may be adapted for mounting at either a boring or turning tool station on the turret. The jaws are adjustably positionable to receive and grip bars of differing size.
