Abstract
A crimping tool is provided including a rotary drive unit and removable extension arm with pivotal jaw arms. The removable extension arm is rotatable about its axis. A locking device is included in the jaw arm assembly such that the jaw arms may be securely positioned in a number of locations to accommodate various working angles. A logic circuit limits the movement of the jaw arms to one complete cycle for each trigger event.
