Crimping capacity: hexagonal crimper for AWG 28-5 (0.08-16 mm2) cable ferrules.Suitable for all types of electrical components for insulated and non-insulated terminals, wire ferrule and end sleeves.Hexagonal crimp profile with six serrated crimp surfaces created by 6 synchronized crimp jaws Quality: The ratchet crimping tool is made of special steel, all stressed parts are made of special steel, oil hardened and tempered.which can increase the service life, labor-saving ratchet device.The non-slip nylon handle with leverage principle is designed to improve crimping effects. Practical Tools: This hexagonal crimping tool is profiled with six serrated crimping surfaces, and created by 6 synchronized crimping jaws, which better fit round breaker shapes.The crimping pliers can self-adjust the suitable diameter for the stripping terminals, the ratchet pliers are precisely crimped, which improves accuracy and reliability when crimping to avoid wasting terminals Convenient Use: Labor-saving ratchet device.The non-slip nylon handle with leverage principle is designed for excellent and easy crimping during use. Materials - safe and reliable.Comfortable handle for easy work.Hexagonal crimp profile with six serrated crimp surfaces created by 6 synchronously driven crimp jaws. These tools have been precisely adjusted (calibrated) at the factory.Optimal transmission of force thanks to the action of the lever for fatigue-free use Great comfort of use thanks to the practical shape and low weight.
