Fully automated adjustment to the respective cross-section-depending insulation thicknesses in a range from 0.03 – 10.0 mm². The so far common fine adjustment of the tool is no longer necessary due to the unique self-infeeding of the cutting depth preventing damage to the conductor. The steel-made restrain jaws with integrated cutting edges very often also allow professional stripping of cables with demanding insulating materials like TEFLON® and Radox. With wire cutter for copper and aluminium wires, multiple stranded up to 10 mm² and single stranded up to 6 mm². Smoothly operating mechanism.
