KNIPEX 1221 Automatic Wire Stripping Pliers 0.03-10 mm² (32-8 AWG) with Cutter, 180 mm

The KNIPEX 1221 automatic wire stripping pliers are a professional-grade tool designed for precise and efficient stripping of single, multiple, and fine-stranded conductors with plastic or rubber insulation. With an automatic adjustment mechanism that adapts to the cable cross-section, these pliers ensure clean and damage-free stripping every time. The integrated wire cutter handles copper and aluminum conductors up to 2.5 mm², while the adjustable length stop allows for repeatable strip lengths from 3.0 to 18.0 mm. The ergonomic multi-component handles provide a comfortable grip, and the replaceable blade cassette extends the tool's lifespan. Made in Germany, these pliers are ideal for electrical installations, industrial applications, and automotive work.
