1 pair of spare blades for 12 21 180. These replaceable blades are adapted for 4 or 6 different conductor cross-sections. They leave the wire undamaged thanks to precision-ground blade shapes, allowing for gentle stripping of even multi-stranded conductors. During the stripping process, the wire is held firmly by clamping jaws. The tool features a length stop for consistent stripping length during repetitive tasks. It has various capacities, including half-moon, square millimetres, square drive, step-like square, triangular, and clamping widths for hexagon, round, and square shapes.
