Crimping pliers for solder-free electrical connections. The ingenious lever translation reduces hand force by up to 30% compared to conventional crimping pliers. Consistently high crimp quality is ensured thanks to precise dies and a forced locking mechanism (unlockable). The tools are precisely set (calibrated) at the factory. Easy handling is achieved through a well-balanced center of gravity, an angled head, and ergonomically shaped handles. The capacity includes half-moons, square millimeters, square drives, square step squares, triangular shapes, and clamping widths for hexagonal, round, and square forms.
