Abstract
A fast-acting die head that is particularly well-suited for use with small-size workpieces employs a set of chasers, each formed as a single piece and having a nose portion that provides two force-receiving surface elements. One of the surface elements is disposed to coact with a camming ring, which is moved axially thereover to close the chasers radially upon the workpiece; the other, underlying surface element receives the force of a spring-loaded plunger, which acts to thrust the associated chaser to an open position when the closing force of the camming ring is removed.
