Cable knife system JOKARI 4-70 for stripping and cutting cables, model 8254510005

The JOKARI Cable knife system 4-70 (model 8254510005) is a modular tool for stripping and cutting round cables with diameters from 4 to 70 mm. The system combines a replaceable bracket mechanism, a metal viewing window for direct monitoring of the cut, and a built-in safety mechanism that reduces the risk of blade-related injuries. It is intended for electrical installation, maintenance and repair work where reliable, repeatable insulation removal and controlled cutting are required. The tool is compatible with the JOKARI accessory range and can be adapted to different common cable types by changing the bracket.

Advantages

The modular bracket system allows one device to cover a wide range of cable diameters, reducing the need for multiple separate stripping tools. The metal viewing window gives the operator visual control during cutting, improving precision and process reliability. An integrated safety mechanism prevents accidental contact with the blade, and the ergonomic design supports comfortable handling during repeated use. TÜV/GS approval for the safety feature provides independent validation of the protective function.

How to use

Select the appropriate bracket for the cable type and diameter, mount it onto the tool and position the cable in the bracket opening. Use the viewing window to visually align the blade with the insulation. Operate the cutting/stripping action according to the tool’s design—advance or rotate the tool as required to score and remove the insulation without damaging the conductor. After stripping, inspect the conductor for nicks or damage and replace the bracket or blade if wear affects performance.

Usage recommendations

Use the JOKARI 4-70 on round cables within the specified diameter range and choose the correct bracket for the cable construction. Wear appropriate personal protective equipment when working with live or potentially live conductors, and ensure power is isolated before cutting where applicable. Regularly check the bracket, blade and safety mechanism for wear and proper function; replace worn parts to maintain cutting quality and safety.
