Data Networking Tools

Data networking tools are the hand tools used to terminate, crimp and test structured cabling such as Cat5e and Cat6. This category currently stocks the C.K punch down tool, used to seat individual cable cores into the IDC terminals of patch panels, data outlets and telephone modules.

It is a small but essential tool for anyone installing data points alongside power. Trade customers get trade pricing, and if you order before 5pm Monday to Friday it will be with you the next working day anywhere in Northern Ireland or the Republic.

Choosing tools for data cable termination

Reliable network performance depends heavily on termination quality. A good punch down tool and the right technique keep pairs twisted, connections tight and test results within limits.

What a punch down tool does

A punch down (or IDC) tool pushes each conductor into an insulation displacement contact, which cuts through the insulation to make the connection, and usually trims the excess wire in the same action. It is used on:

Patch panels in cabinets and comms rooms
Data and RJ45 keystone outlets
Telephone modules and connection blocks

Good termination practice

Strip only as much outer sheath as needed and keep the pair twists as close to the terminal as possible, as untwisting too much affects performance. Follow one wiring scheme, T568A or T568B, consistently throughout the installation, matching the colour coding marked on the outlet or panel. Make sure the blade is the correct way round so it trims the waste end, not the cable side. Respect the cable's minimum bend radius and avoid over-tightening ties on data runs.

Other tools to consider

For patch leads you will need an RJ45 crimper, such as the one in the strippers and crimp tools range. A cable tester or certifier confirms each link is wired correctly and performs to the expected category. Cable labels, a sheath stripper sized for data cable and a pair of fine side cutters complete a basic data termination kit.

FAQ's Ask Your Own Question

What is a punch down tool used for?: A punch down tool is used to terminate data and telephone cable conductors into IDC terminals on patch panels, data outlets and connection blocks. It presses each wire into the contact, which cuts through the insulation to make the connection, and usually trims off the excess wire at the same time for a neat, reliable termination.
Should I use T568A or T568B wiring?: Both T568A and T568B work equally well for data; the important thing is to use the same scheme at both ends of every link and throughout the installation. T568B is very common in commercial installations in the UK and Ireland, but check the project specification or match any existing cabling. Outlets and panels are usually colour-coded for both schemes.
Can I use a punch down tool on Cat6 cable?: Yes, a standard IDC punch down tool can terminate Cat5e and Cat6 cable on compatible patch panels and outlets. Cat6 conductors are often slightly thicker and the cable may have a central separator, so prepare carefully and keep pair twists tight to the terminal. Some Cat6 connectors use tool-less designs, so check the manufacturer's instructions.
How much should I untwist pairs when terminating?: Keep untwisting to an absolute minimum, ideally no more than about 13mm for Cat5e and Cat6, so that the cable's twist rate is maintained right up to the terminal. Excessive untwisting increases crosstalk and can cause the link to fail testing. Strip only the sheath length needed and lay the pairs directly into their positions.
Do I need to test data cables after termination?: Yes, testing is strongly recommended. A basic tester confirms wiremap and continuity, showing crossed, split or open pairs, while a certifier verifies the link meets the performance of its category and is often required for warranties on commercial installations. Label each link and record results so faults can be traced later.
Can I keep data and power cables in the same containment?: Data and mains power cables generally need to be segregated, either by separate containment, a divider or minimum separation distances, both for electrical safety and to reduce interference. The requirements depend on cable types and voltage bands. Check the current edition of BS 7671 and the relevant structured cabling standards for your installation.
