Knipex 12 21 180 Insulation Stripper Adapted Blades 180mm 0.5-6mm2

The Knipex 12 21 180 is a 180 mm insulation stripper fitted with interchangeable, precision-ground shaped blades that strip conductors from 0.5 to 6.0 mm2 without nicking or damaging the wire. Two blade configurations are available - one matched to conductor diameter covering four sizes and one matched to cross-section covering six sizes - giving the tool broad coverage across common cable gauges. An adjustable length stop and automatic spring return make it especially productive for repetitive stripping tasks in panel wiring and production environments.

Features and benefits:

• Interchangeable blades available in two configurations: four sizes matched to conductor diameter or six sizes matched to conductor cross-section, adapting the tool to different wiring standards
• Precision-ground shaped blades remove insulation cleanly without damaging the conductor, including fine-stranded flexible cables
• Clamping jaws grip the wire securely during stripping, preventing movement and improving cut quality
• Adjustable length stop allows a consistent stripping length to be set and repeated across an entire batch of conductors
• Compression spring automatically returns the tool to the open position after each stroke, reducing hand fatigue in repetitive work

Applications:

• Stripping insulation from copper conductors during control cabinet and distribution board assembly
• Preparing wire ends for screw terminals, ferrules, and push-in connectors in building electrical installations
• High-volume production wiring where a consistent strip length is required across many identical conductors
• Stripping fine-stranded or flexible cables where conventional blades risk cutting individual strands
• General electrical maintenance, repair, and installation work on conductors from 0.5 to 6.0 mm2
