HELUTOOL HAM 29: Quick and Easy Cable Stripping Tool
With the HELUTOOL HAM 29, electricians and installers have a convenient and useful tool that saves time and effort when laying and connecting cables.
1. What is cable stripping?

Cable stripping is the process of removing the outer insulating layer or semiconductor layer of the cable to facilitate inspection and processing of the cable ends during installation or connection. This process is very common in electrical engineering, electronic equipment assembly, and cable manufacturing. The accuracy and efficiency of cable stripping are crucial in ensuring the quality of connections and the reliability of the entire electrical system.
2. Some methods for stripping electrical cable insulation

Some types of cable stripping accessories from HELUKABEL
2.1 Cable stripping pliers
Wire strippers are an indispensable tool for electricians. This type of pliers can be adjusted to fit different wire cross-sections without damaging the conductor core. They are used when it is necessary to remove the insulation at the end of the wire so that the copper or aluminum core can conduct electricity.
Stripping wires with pliers is the most common method, often used to strip wires in residential settings, fuse boxes, or control cabinets, in preparation for installing terminals, connectors, or cable clamps.
Additionally, there are specialized pliers designed specifically for stripping thin wires. They function similarly to standard cable strippers but are specially engineered to handle wires with extremely small cross-sections, even as small as 0.4 mm², ensuring clean stripping without damaging the conductor core.
2.2 Wire stripping tools
Cable stripping tools are typically tubular in shape, can be opened lengthwise, and have a cutting blade attached inside. Multi-purpose cable strippers also feature an external sliding bar, allowing the cutting depth to be adjusted according to the outer diameter of the cable to be stripped (e.g., 2.5 mm² or 4 mm² cross-section wires).
3. Features of the HELUTOOL HAM 29

3.1 Improved cable stripping tool from HELUKABEL
HELUKABEL expands its accessory portfolio with the HELUTOOL HAM 29, an innovative outer jacket cutter. This universally applicable tool is designed for cable diameters ranging from 4.5 to 29 millimetres. The blade, made of hardened steel, is suitable for both soft and hard insulation materials and the cutting depth can be precisely adjusted up to three millimetres. As a result, the outer jacket of cables and wires can be effortlessly removed without damaging the underlying insulation or braiding.
3.2 Key Advantages of HELUTOOL HAM 29
HELUTOOL HAM 29 impresses with the following outstanding advantages:
- High precision: Cutting depth can be adjusted up to 3 mm, ensuring that the inner core layers of the cable are not damaged.
- Versatile: The tool features a quick-release spring clamp system that holds the cable securely in place with ease and precision. Users can easily adjust the device to make circular cuts, spiral cuts, or straight cuts with a simple motion.
- Safety assurance: The improved design minimizes the risk of injury to users.
- Highly effective: The cutting blade is designed to suit most types of cable insulation layers. Quick and efficient operation saves time for engineers and electricians.
- Simple operation: No jamming during operation thanks to the vertical pulling mechanism, ensuring a smooth cutting process.
- Durability: The risk of damaging the cable during stripping or cutting is eliminated thanks to the sturdy structure and blade protection against jamming and damage caused by improper use.
- Ergonomics: The HELUTOOL HAM 29 tool also impresses with its carefully researched ergonomic design. Optimized to fit the user's hand, it ensures comfortable operation and prevents hand fatigue even during prolonged use.
The support surface for stripping is designed to be smooth, allowing for smooth and fatigue-free work. In addition, with its compact size, this cable stripping/cutting tool fits into any toolbox or bag, making it convenient and easy to carry around.
3.2 Technical characteristics of HELUTOOL HAM 29
- Wide range of applications: suitable for cables with diameters from 4.5 mm to 29 mm.
- Multi-material: suitable for both soft and hard cable insulation layers.
- Special blade processing: allows for clean and neat removal of the outer layer.
- No deviation when cutting: thanks to axial pulling, which ensures straight and precise cuts.
- Flexible cutting depth adjustment: maximum 3 mm, with small adjustment increments of 0.1 mm.
- Protect the inner core layer: the underlying conductor layers are not damaged during stripping.
- Safety lock system: prevents the tool from opening in "rip cut" mode, protecting the blade from damage when operated incorrectly.
- Easy to use: simply turn the adjusting ring to the "longitudinal cut" symbol and pull along the length of the cable to complete the operation.
