Weicon Cable Stripper No. S 4-28 Spiral

WEICON Cable Stripper No. S 4-28 Spiral is a professional cable processing hand tool developed for the precise, fast, and safe stripping of standard round cables. The product is designed to work on common cables with outer diameters from 4 to 28 mm and, in addition to conventional circular and longitudinal cutting, also offers a spiral cutting function. This additional feature helps remove complex insulation more controllably in cases where standard methods are less effective. Manufactured by WEICON in Germany, the model stands out with its fiberglass-reinforced polyamide body and blade system designed for safe use.

Technical structure and cutting capability of the WEICON S 4-28 Spiral
The core design of this model is based on a rotating internal blade system capable of circular, longitudinal, and spiral cutting on both soft and hard cable insulation. According to the technical data sheet, the cutting depth can be adjusted precisely from 0 to 3 mm in 0.1 mm increments, helping reduce the risk of damaging deeper layers. The internal blade is adjustable and replaceable, and the tool also features an integrated retractable safety blade. The housing material is specified as fiberglass-reinforced polyamide, while the product has a length of 145 mm and a weight of 80 g. This structure provides a balanced combination of durability and controlled handling for field use.

Spiral cutting mechanism and application method
The distinguishing feature of the product is its ability to perform spiral cutting in addition to standard circular and longitudinal cuts. During use, the cutting depth is first adjusted according to the cable, then the internal blade is fixed with the spiral key and the function adjustment mechanism is set to spiral mode. After the spiral cut is applied to the end of the cable, a small incision is made at the end of the insulation with the integrated safety blade, allowing the sheath to be removed more easily. To return to circular or longitudinal cutting, the spiral lock is disengaged and the blade is released to move freely again. This design provides a more controlled working advantage, especially on difficult and complex insulation types.

Application areas and compatible cable types
The WEICON S 4-28 Spiral can be used in electrical panel assembly, building electrical installations, automation infrastructure, field cabling work, maintenance and repair processes, and general industrial electrical installation. The technical documentation states compatibility not only with PVC-insulated stranded and solid conductors, but also with PUR cables as well as round and damp-room cables. For this reason, the product is functional not only in standard installation work but also in applications involving cables with more demanding insulation structures. The spiral cutting feature offers an important operational advantage in cable types where conventional outer sheath opening methods are not sufficient. The replaceable blade design also supports service continuity during regular use.

Key advantages and safe-use approach
The main advantage of this cable stripper model is that it combines precise cutting depth adjustment, multiple cutting functions, and an integrated safety blade in a single housing. The spiral cutting feature in particular provides controlled stripping capability not only on standard round cables but also on more problematic insulation structures. Its lightweight and compact design makes it easier for maintenance teams, electrical installation companies, and industrial service units to carry and use. The manufacturer also clearly states that this tool should only be used on de-energized, non-live cables and conductors, indicating that it should always be used in accordance with safe working procedures.
