The Eclipse 902599 Quik Crimp 6 Ton Battery-Operated Crimper with Die Set, Micro Computer Control System is a battery-operated hex crimping tool with die sets. Its microcomputer control system automatically detects pressure when crimping, with double safety protection. This tool is equipped with a pressure release function and a double piston, which is characterized by a fast approach towards the connector material, then a transfer to high pressure automatically with slower crimping. The crimping head can be smoothly turned by 350° around the longitudinal axis in order to gain better access to tight corners and other difficult working areas. The 902-599 accepts industry standard 6 ton dies.
