A connector attaching tool is for attaching a coaxial cable connector to a coaxial cable by longitudinal compression of the coaxial cable connector. The tool includes a tool body defining therein a connector compression chamber and a plunger receiving chamber longitudinally adjacent thereto. A plunger having a plunger head is within the plunger receiving chamber and a plunger shaft extends outwardly therefrom. A handle is carried by the tool body and is movable from a retracted position to a compressed position for advancing the plunger shaft to drive the plunger head to longitudinally compress the coaxial cable connector within the connector compression chamber to thereby attach the coaxial cable connector to the coaxial cable. The tool body defines a connector magazine chamber for storing a plurality of coaxial cable connectors. A biasing member is within the connector magazine chamber for urging the coaxial cable connectors toward the connector compression chamber.
