Cable stripper Knipex 12 40 200 SB

The Knipex 12 40 200 SB cable stripper is a compact hand tool for stripping insulation from single, multiple and fine‑stranded conductors with plastic or rubber insulation. It adapts automatically to the cable cross‑section and protects the conductor from damage. The tool includes an adjustable cutting depth and an integrated wire cutter suitable for copper and aluminium: multiple‑stranded up to 10 mm² and single‑stranded up to 6 mm². The body is made of fiberglass‑reinforced plastic and the blade of oil‑hardened special tool steel.

Advantages

The automatic adaptation to different cross‑sections and the adjustable cutting depth ensure accurate stripping across a wide range of insulation types and sizes. A smoothly operating mechanism and low weight make the tool easy to handle during repetitive work. Replaceable stripping blades and clamping jaws extend service life. The integrated cutter handles copper and aluminium conductors within the stated cross‑section limits.

Suitable for

• Stripping single‑core copper or aluminium wires up to 6 mm²
• Stripping multiple and fine‑stranded conductors up to 10 mm²
• Electrical installation and maintenance tasks in residential and commercial settings
• Precise cable preparation for control panels and connection blocks

How to use

Place the cable between the stripping jaws and close the tool so the blades engage the insulation. The tool adapts automatically to the cable cross‑section; adjust the cutting depth if working with thicker or harder insulation. Pull the tool along the conductor to remove the insulation. For cutting, use the integrated wire cutter for copper or aluminium within the specified cross‑section limits. Replace stripping blades or clamping jaws when wear affects performance.

Usage recommendations

Use the adjustable cutting depth to avoid nicking conductors and inspect stripped conductors visually before making connections. Replace worn blades promptly and keep the tool clean and lightly lubricated to maintain smooth operation.
