ABSTRACT:
Each of a pair of die nest members for a crimping tool comprises preferably four individual arms extending radially outwardly from a central longitudinal axis in a cruciform configuration permitting each arm to be selectively indexed into operative position in one jaw of the tool for disposition adjacent any one of the similarly indexable arms of the other die nest member in the other jaw of the tool to provide a selectively determinable pattern of mating die nest combinations. Each die nest member may be rotated about its transverse axis to insure that the desired die nest combination will be located at a position employing the most favorable mechanical advantage of the tool.
