A hand-held tool for terminating connectors onto a coaxial cable has an elongated body and an end stop and plunger on the body, the plunger being controlled by a lever arm which will axially advance the plunger toward and away from the end stop to radially compress a portion of the connector into firm crimping engagement with the end of the coaxial cable. To accommodate different lengths of connectors, a plunger permits mounting of different length adapter tips to vary the axial spacing between the adapter tips and the end stop according to the length of connector being terminated.
