Self-adjusting crimping pliers for cable lugs, designed for crimping cable lugs according to DIN 46228 parts 1 and 4. The self-adjusting function adapts to the desired size of the cable lug and prevents incorrect crimps that could occur from using the wrong tool. Cable lugs are inserted from the front into the pliers, ensuring consistently high crimp quality, thanks to the integrated locking mechanism with automatic release. The lever provides optimal power transmission and reduces fatigue during use. The compact design and lightweight construction ensure high user comfort. The application range extends from 0.08 to 10 mm².
