Bootlace ferrule crimping tool
WKK provides practical crimping tools for both insulated and non-insulated bootlace ferrules ranging from 0.5 to 2.5 mm². These tools are used to crimp the ferrule onto the stripped end of the wire. Thanks to the crimping design, the ferrule is evenly shrunk around the conductor, ensuring optimal electrical conductivity and mechanical connection. This prevents loose or poorly contacting connections that could cause deformation or oxidation. During use, first strip the end of the cable, slide the correct-sized ferrule over the conductor, and use the tool to crimp the ferrule properly. Afterwards, you can attach the finished product to, for example, a spring or screw terminal.
Application: Attaching bootlace ferrules for secure cable connections
The primary application of a bootlace ferrule crimping tool is to secure ferrules to cable ends, making it easy, safe, and durable to connect these cable ends — for example, to screw terminals or distribution boards. The ferrule ensures that the fine copper wires are neatly contained, make proper contact with the terminal, and do not come loose under mechanical stress or vibration. According to guidelines like NEN 1010, the use of bootlace ferrules is mandatory for fine-stranded cables in screw terminals. The result: a reliable connection, reduced risk of faults, and a tidier installation.
Different types of bootlace ferrule crimping tools
There are various models of crimping tools that differ in crimp type (square, hexagonal, V-shape), range (e.g., 0.25 mm² to 10 mm² or larger), and mechanism (manual, with ratchet, automatically adjustable). Standard crimping tools are available for light installation work, as well as heavy-duty professional models for larger wire sizes or industrial applications. The crimp shape (e.g., square versus hexagonal) may also vary depending on whether the connection is round or a screw terminal.
Application areas
Bootlace ferrule crimping tools are used in a wide range of installations: electrical installations in buildings, panel building, machinery manufacturing, panel assembly, distribution boxes, solar energy systems, and anywhere cable ends need to be neatly finished and connected. Due to their high reliability, they are crucial in situations with vibrations, fluctuating temperatures, or where ease of maintenance is important. They are also indispensable in control panels or switchboards where many cables converge.
How to choose the right bootlace ferrule crimping tool
When choosing the right bootlace ferrule crimping tool, consider the following important criteria: crimp range (matching the wire sizes you use), ferrule type (insulated or non-insulated), crimp shape and quality of the tool (such as jaw profile and ratchet function), ergonomics, and frequency of use. For installations with many cables and fine-stranded wire, a tool with automatic adjustment and a ratchet mechanism is recommended, while a handle-type tool may suffice for occasional use. Good tools provide even pressure and do not deform the ferrule, improving the contact quality.
It is also useful to choose a tool that matches the insulation thickness and ferrule size available in your stock.
