Work-holding devices for use with work loading and transferring apparatus for automatically handling and moving gear blanks and gear pieces from one station to another relative to gear-cutting machines. The work-holding devices, which are positioned at the ends of loading and transfer arms, each include a cup means for contacting and centering a gear piece relative to the holding device, and jaw members for effecting a tight grip on the workpiece. These different embodiments of the workholder device are disclosed, namely, (H-1) a basic device for handling work blanks which have not been cut at all, (H-2) a device similar to H-1 but including stock-dividing means suitable for orienting a rough cut workpiece for a further cutting operation, and (H-3) a device similar to H-2 but including a different form of stock-dividing means for orienting a workpiece between two finish-cutting operations.
