Unior insulation stripper with hooked blade, model 610930 (for 4–28 mm cable diameters)

The Unior insulation stripper with hooked blade, model 610930, is a hand tool designed for controlled removal of insulation from round cables with diameters from 4 to 28 mm. Intended for electrical and telecommunications work, maintenance and installation tasks, this stripper provides a precise cutting action that minimizes damage to conductor cores. The hooked blade geometry helps to engage and lift insulation cleanly, while the compact form supports both field and workshop use.

Advantages

The hooked blade allows accurate engagement with cable insulation, reducing the risk of nicks in conductors and enabling repeatable stripping results. The stripper’s diameter range covers a wide variety of round cables used in power, signal and telecom applications. Its hand-tool format offers portability and immediate usability without power sources, and the blade design supports controlled stripping even in constrained workspaces.

Suitable for

• Stripping insulation from round power cables and multi-core cables within 4–28 mm diameter range
• Electrical installations, maintenance and repair work
• Telecommunications and data cable preparation
• Workshop and on-site field service tasks requiring manual stripping

Key specifications

• Cable diameter range: 4–28 mm suitable for round cables
• Blade type: hooked blade for controlled lifting and cutting of insulation
• Operation: manual hand tool for field and workshop use
• Application: designed for electrical and telecommunications cable insulation removal

How to use

Select a cable with diameter within the specified range and position the hooked blade against the insulation at the intended stripping point. Apply steady pressure while rotating or sliding the tool as required to score and lift the insulation; then pull the insulation away from the conductor to expose the core. Maintain a controlled motion to avoid cutting into conductor strands. Inspect the exposed conductor for damage before making the electrical connection or further processing.

Usage recommendations

Regularly inspect the hooked blade for wear and replace if the cutting performance degrades. Use the tool on cables within the specified diameter range to ensure clean stripping. For safety, disconnect power and verify circuits are de-energized before stripping live conductors; wear appropriate personal protective equipment during use.
