Crimping pliers for solder-free electrical connections. The ingenious lever transmission reduces hand force by up to 30% compared with regular crimping pliers. Consistently high crimping quality is ensured thanks to precision dies and a forced locking mechanism (unlockable). Tools are precisely calibrated in the factory for accuracy. Easy handling is achieved due to a well-balanced center of gravity, an angled head, and ergonomically shaped handles. Capacity includes half-moon, square millimeters (0.25 - 6 mm²), square drive, step-like square, triangular, and clamping widths for hexagon, round, and square shapes.
