Greenlee EK50ML120B bare tool with 12mm jaw. The first electromechanical crimping tool with PowerSense Technology which allows you to hold your work during preparation before starting the crimp. Intelligent crimping system technology monitors amp draw for each crimp and provides a visual alert if a crimp does not complete a full cycle. Crimp up to 90 percent less force. 65 percent faster crimping cycle versus ratcheting tool. 10.8V Li-Ion Battery can perform up to 250 crimps on one battery charge. LED battery level indicator allows the user to monitor battery charge so they always know when the battery needs to be recharged. LED work light allows the user to illuminate their work in dark areas. When crimping is complete, simply release the trigger to open the jaws for the next crimp. Over-molded tacky grip area makes gripping the tool easier and more comfortable.
