Insulation cable cutter with interchangeable blades for four or six different conductor cross-sections. Thanks to precisely ground blade shapes, the wire remains undamaged; even multi-stranded conductors are gently stripped. During the stripping process, the wire is securely held by clamping jaws. It features a length stop for consistent stripping lengths during repetitive work. The capacity includes half-moon, square millimeter, square drives, step squares, triangular, and clamping widths for hexagonal, round, and square tubes.
