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-guiding (lockable) locking mechanism. The tools are factory calibrated for precision. Easy handling is achieved through a well-balanced center of gravity, an angled head, and ergonomically shaped handles. The capacity includes half-moon, square (0.5 - 6 mm²), step-shaped square, triangular, and clamping widths for hexagonal, round, and square shapes.
