Description

The KNIPEX Insulation Stripper (12 21 180) is a precision manually-adjusted wire stripper with replaceable blade sets adapted to specific conductor cross-sections or diameters. The replaceable blade cassette system allows the tool to be easily reconfigured for different wire gauges, giving professionals both flexibility and precision — ensuring that each strip leaves the conductor undamaged regardless of insulation thickness.
At 180mm, this stripper provides comfortable handling for panel wiring, switchboard installation, and control cabinet assembly. The plastic-coated handles are comfortable over extended use, and the jaw action is smooth and repeatable. The replaceable blade design extends the effective service life of the tool significantly compared to fixed-blade alternatives.
This model is particularly valued for precision work where conductor integrity is critical, such as fine multi-strand signal cables, control wiring, and data conductors where even minor nicking of the conductor strands could compromise performance or reliability.
