Pick the size that suits your usual work and get the right pair on site.
What Are Knipex VDE Side Cutters Used For?
- Cutting copper conductors cleanly during first fix and second fix, whether you are trimming singles at a board, clipping flex in a plant room, or tidying final connections at sockets and switches.
- Snipping cable ties, sleeving, and small plastic fixings when dressing panels or keeping consumer unit work neat, without having to swap between tools for every little job.
- Working in tight electrical spaces such as back boxes, trunking runs, and control panels where knipex insulated side cutters give you proper control without bulky handles getting in the way.
- Handling day to day maintenance and fault finding where Knipex VDE cutters electrical insulation matters, especially when you are working near live components and need compliant hand tools in the bag.
- Cutting softer wire and general site materials cleanly on refurb jobs, where a decent pair of knipex vde diagonal cutters saves hand strain compared with cheap cutters that pinch rather than bite.
Choosing the Right Knipex VDE Side Cutters
Match the size to the work you actually do. Do not buy bigger just because it looks tougher.
1. 160mm for everyday electrical work
If most of your day is sockets, lighting, board work, and general maintenance, a knipex vde diagonal cutter 160mm is usually the sweet spot. It gets into boxes and panels easily, rides well in the pouch, and still has enough leverage for regular copper and cable ties.
2. 180mm when you want more leverage
If you are regularly cutting thicker conductors or doing heavier site electrical work, knipex vde side cutters 180mm give you more purchase with less effort. The trade-off is a bit more bulk, so they are less handy in cramped spots.
3. Insulation matters if they are for electrical work
If these are going anywhere near electrical tasks, buy proper knipex 1000v side cutters with VDE insulation, not standard dipped handles. That rating is the whole point when you are working near live parts or need compliant kit on the van.
4. Buy for the material, not just the badge
If you mainly cut copper, flex, and lighter wire, standard Knipex insulated diagonal cutters are spot on. If you expect them to chew through hard or piano wire all day, check the cutting capacity properly rather than assuming any side cutter will do it.
Who Uses These on Site?
- Sparkies use knipex vde side cutters every day for trimming conductors, snipping cable ties, and cleaning up tails during first fix, testing, and final fit off.
- Maintenance electricians keep a pair in the pouch for fault finding and small repair work, because they are quicker to grab than larger cutters when working in panels, risers, and plant rooms.
- Industrial fitters and control panel builders swear by knipex vde diagonal cutters for repeated neat cuts on copper and fine wire, especially where hand comfort matters over a full shift.
- Apprentices and improvers are better off buying decent knipex insulated side cutters early, because a reliable pair gets used constantly and saves replacing cheap tools that loosen up fast.
Choose the Right Knipex VDE Side Cutters for the Job
Use this quick guide to match the cutter size and type to the work in front of you.
| Your Job | Knipex VDE Side Cutters or Type | Key Features |
|---|---|---|
| General socket, switch, and lighting work | 160mm VDE side cutters | Easy to carry, good control in back boxes, enough cutting power for everyday copper and flex. |
| Consumer unit and panel tidying | Compact insulated diagonal cutters | Neat cuts on tails, cable ties, and smaller conductors without bulky handles fouling nearby components. |
| Heavier electrical installation work | 180mm VDE side cutters | More leverage for thicker wire, less hand effort, better suited to repeated site use. |
| Van tool kit for maintenance callouts | Mid-size 1000V side cutters | Proper electrical insulation, useful all-round size, quick to grab for repairs and fault finding. |
Common Buying and Usage Mistakes
- Buying oversized cutters for fiddly work can be a pain in tight boxes and panels. If most of your jobs are domestic or light commercial, 160mm is often the handier choice.
- Using VDE side cutters as a general site pry bar or twisting tool will knock the jaws out and ruin the cut. They are for cutting, not levering clips or opening knockouts.
- Assuming insulated handles mean indestructible protection is how tools get unsafe. Check the insulation regularly and replace them if the grips are cut, burnt, or badly damaged.
- Trying to cut wire that is too hard for the tool will chip the edges and leave you with poor cuts after that. Check the cutter capacity before using them on hardened materials.
- Leaving cutters wet or buried loose with other steel tools soon leads to rough action and edge wear. Wipe them down and store them properly so they stay smooth and accurate.
160mm vs 180mm vs High Leverage Cutters
160mm VDE Side Cutters
Best for everyday electrical work, especially sockets, lighting, and panel tidying. They are easier to control in tight spaces and lighter in the pouch, but they give you less leverage on thicker wire.
180mm VDE Side Cutters
A better choice if you want more cutting force without stepping into specialist cutters. They suit heavier installation work, though they can feel a bit big for cramped domestic boxes.
High Leverage Cutters
These are for lads cutting tougher material more often and wanting less strain through the hand. They are not always the smallest option, but they pay off if standard cutters feel hard work by midday.
Maintenance and Care
Wipe Them Down After Use
Dust, plaster, and damp site grime soon work into the joint. A quick wipe at the end of the day keeps the action smooth and stops corrosion starting around the pivot.
Check the Insulation
Inspect the VDE handles for cuts, deep nicks, burns, or loose sections. If the insulation is damaged, do not chance it on electrical work. Replace the tool.
Oil the Joint Lightly
One drop on the pivot now and then is enough. If the joint starts feeling stiff or gritty, sort it early before the cutters start binding and making rough, uneven cuts.
Use the Right Cutter for the Wire
Do not chew through material beyond the stated capacity just because it nearly fits. That is the fast way to nick or flatten the cutting edges and spoil a good pair.
Store Them Properly
Keep them in a pouch, case, or dry toolbox rather than loose in the bottom of the van. It stops the edges getting knocked about and helps the insulation last longer.

Knipex VDE Side Cutters FAQs
What are VDE side cutters used for?
They are mainly used for cutting copper wire, flex, cable ties, and light site materials during electrical installation and maintenance work. On a real job, they earn their keep in back boxes, panels, consumer units, and trunking where you need a clean cut and insulated handles you can trust.
Are VDE side cutters tested to 10;000V?
Yes. Proper VDE tools are typically individually tested at 10000V and rated for safe working up to 1000V AC. That said, the rating only means something if the insulation is intact, so always check the handles for cuts, burns, or damage before using them.
What size VDE side cutters should I buy?
For most sparks, 160mm is the safe bet for everyday work because it fits boxes, panels, and pouches without being clumsy. If you regularly cut thicker conductors and want more leverage, 180mm is worth it, but it is less nimble in tight spots.
What is the difference between side and diagonal cutters?
In practice, most people use the names interchangeably for this type of cutter. The main point is the cutting edges sit at the side of the head for flush, controlled snips on wire and similar materials, rather than gripping or twisting like combination pliers.
Can VDE side cutters cut hardened wire?
Some can handle harder wire, but not all of them are meant for repeated cuts on hardened material. Be honest about what you cut most. If it is mainly copper and general electrical materials, standard models are fine. If hard wire is a regular thing, check the exact cutting spec before you buy.
Are Knipex insulated side cutters worth paying more for?
Yes, if they are getting used daily. Knipex cutters tend to hold their edge, stay tight at the joint, and feel better in the hand over long shifts. Cheap insulated cutters often start fine, then loosen up, cut poorly, and end up replaced too soon.
