Insulation cable stripper with interchangeable blades for four (adjusted to diameter) or six (adjusted to cross-sections) different conductor cross-sections. The precision-ground blade shapes do not damage the wire; even multi-stranded conductors are gently stripped. During stripping, the wire is held securely by clamping jaws. It features a length stop for a consistent stripping length during repetitive work. The capacity includes half-moons, square millimeters, square drives, step squares, triangular shapes, and clamping widths for hexagonal, round, and square forms.
