Klein Tools VDV226-110 Ratcheting Modular Data Cable Crimper / Wire Stripper / Wire Cutter for RJ11/RJ12 Standard, RJ45 Pass-Thru Connectors

Easy to use. Makes excellent cables. Purchased to replace older style pliers that consistently failed to crimp pin 1 pr pin 2. Simply using this crimper on cables that had been made by the pliers made the cables complete. I can make a cable now in a few minutes and every cable works, every time I have tested them. This crimper is a major time saver and reduces stress.

Worked flawlessly on the first try. I made two cat6 cables quickly without any mistakes. This review is 4.5 stars (or maybe between 4.5 and 5) but Amazon only allows whole-stars. I decided on 5 because 4 is too low. The tool feels sturdy and the mechanism is firm but not tight (perfect). This is the first time I've used a ratcheting crimper, and I'm a fan over non-ratcheting crimpers (though it's been decades since I last crimped any RJ45 connectors). The sheath-cutter works surprisingly well, though you should always inspect the individual wires to see if you have cut their sheaths as well. If you have large hands, this tool will feel small, but there is no issue using it. This tool seems like it would be equally easy to use for right-handers and left-handers, though each would likely choose a different grip (thumb near the fulcrum for left-handers, thumb near the end of the handle for right-handers). This tool really is great, I only have a few small issues. My only real complaint about this tool is that it can't be closed for storage. It's got a ratcheting handle so you can clamp-down on the connector during crimping, but then it always springs back to its fully-open position. Imagine having to store all your scissors in the "X position" (open) rather than the "Y position" (closed). I guess I'll just get some twine to hold it closed when it's in the drawer. There is a "safety override" knob on the handle. It's labelled "override" on the tool and the instruction card helpfully clarifies that as a "safety override", and it's used to allow you to release the ratchet before it's reached it's final position. I kinda feel like the solution to the "won't stay closed" problem could have been solved using this same knob, but rotated in the other direction, perhaps. When inserting the RJ46 connector into the tool for crimping, the connector does not lock like it would, say, in an actual Ethernet connection. This means that you have to ensure that you really, REALLY made sure to push the connector all the way in, and that it doesn't move at all as you perform the crimp. The crimping operation does not push the connector either way, so you SHOULD be okay, but you are on your own to ensure proper alignment. The "crimp nest" appears to be a separate die-cast component and could easily have been designed to have a clip to ensure proper and steady positioning. This crimper unfortunately comes with no connectors, and the bundle with connectors is an extra $15 for 50 connectors. I decided to buy much cheaper connectors and they worked perfectly fine. I kinds thing think this too should come with some really small number of connectors, like maybe 4. Otherwise you have to buy a lot of them if you only need a few. I suppose if you are buying a crimping tool, you are not interested in making just one or two cables, but at least it would let you get a sense of what quality connectors you would need to buy, or to compare to others you might find. The wiring diagrams directly on the tool are great, but they are stickers. I suspect they will wear-off over time. Anything that won't last the life of the tool isn't really worth much. Sure, you can find the wiring pattern on the internet, but having it on the tool is SUPER nice. The instructions tell you to strip between 1.5" - 2" of the sheathing which I found to be way more than necessary, but it depends upon the type of connector and a few other factors. In my case, I decided to start conservatively and cut a full 2" off the end, and ended up with 3/4" or more of discard wire pieces being sheared-off during the crimp (which is the point of the "pass-thru" design). That seemed to me like a lot of waste. In one instance, the outer wires weren't completely cut during the crimp/shear operation, but I could just twist them off the end of the connector after I removed it from the tool. I think the blade could afford to be 1/16" wider or so. The instructions don't make this suggestion, but after you have straightened each of the individual wires for insertion into the connector, I would recommend trimming them all flush to make the placement easier. The cutter doesn't look like it would work well for this, but it does: just put the wires across the oddly-angled center of the tool and close the jaws. It looks like there is plenty of space to lose stray cut-ends of wire into this tool. I've only had it for 24 hours so I haven't had much opportunity to fill it up with junk and have to clean it. There are 3 pins holding the two faces of the tool together, and each of the 3 has a retaining ring on it, so I'm optimistic about the serviceability of this tool. Had them been rivets or some other permanent fastener, I'd be less optimistic.

The Klein Tools VDV226-110 Ratcheting Modular Data Cable Crimper / Wire Stripper / Cutter is a tool every tech professional needs. The ratcheting mechanism makes crimping effortless and precise, while the integrated wire stripper and cutter save time and reduce clutter in your toolkit. It feels solid and well-balanced, with clean, sharp cuts every time and no frustrating slips. Assembly and adjustments are intuitive, and it handles all standard modular data cables flawlessly. Durable, reliable, and thoughtfully engineered — exactly the kind of high-quality tool I love testing and recommending.

This Klein crimper is a massive improvement over the cheap no-name ones I bought the first time. The ratcheting action is smooth, the leverage is great, and it makes clean, consistent crimps without having to crush the handles like a gorilla. It strips and cuts cleanly too, which is more than I can say for the budget tools. Everything locks in straight, the connectors seat perfectly, and the finished cables actually look professional instead of “well, hopefully this works.” After switching to this, I’m not wasting connectors anymore. If you want a tool that feels solid and works the way it should every single time, this is the one. Would absolutely buy again.

Works very well for the intended purposes.

This cable crimper is well built and solid. It cuts cable and strips outer jacket without any effort. Crimping, not so good. Of the eight wires, one and eight do not sever completely and require a second and even a third crimp and may still have to be “wiggled” off which is why I removed a star. I like the fact that the wire diagrams are on the handle to aid in correct alignment of the wires. Overall I’m satisfied with this tool.

I honestly wish I'd bought this sooner. I was turned off by the price, but it's worth it for all of the time it saves you. My previous tool would crush the fitting and I'd end up having to cut it off and try again. No more! Plus, it has the wire patterns printed on both sides of the tool for reference before you cut. It is truly a fantastic, well made tool.

Very high quality tool. Easy to use and very nicely designed.

Avevo provato altra crimpatrice considerato il prezzo di questa. Rimandata indietro subito. La toglierina non funzionava i cavi crimpati male oltre ad essere il lavoro davvero “sporco”. Così decido di comprarla. Che dire , alla prima prova lavoro perfetto e funzionante,cosa che con l’altra nemmeno avendolo rifatto 4 volte. Altro suggerimento,comprate gli spinotti della stessa marca,altro mondo.

Après avoir utilisé le produit similaire vendu par Amazon. (2 mille + notes / note 4.x et ayant des résultats peu fiables. De nombreuses tentatives et nécessitant de refaire les sertissages pour obtenir une connexion solide, j'ai été extrêmement satisfait de ce produit. Mécanisme à cliquet, assure une connexion solide et complète. La bande et la coupe incorporées sont très pratiques et précises. Les schémas de câblage des deux côtés de l’outil constituent une confirmation infaillible. Les connecteurs sont un peu plus chers que la marque XXX, mais valent le coût compte tenu du gain de temps et de la fiabilité. Fabriqué aux États-Unis ou en Chine... encore une fois, un prix inférieur ne signifie pas toujours un meilleur rapport qualité-prix. Je recommande fortement ce produit

De muy buena calidad. Compactas y muy prácticas. Hasta ahora solo la he usado con terminales regulares, pero funciona al 100. La recomiendo

Tenía una crimpadora de toda la vida de calidad, pero cuando descubrí los conectores "pass through", vi que era otro nivel: se acabaron los errores, y conexiones de calidad. Pero hacía falta una crimpadora que estuviera a la altura, y después de leer muchos comentarios me decanté por esta. No es barata, pero el dinero invertido por ahora merece la pena hasta al último céntimo. Es robusta y pesa lo suyo con lo que se nota que no es plástico ni materiales de poca monta. La cuchilla corta a la perfección, y si eliges unos conectores RJ45 medio buenos (en mi caso los he comprado VCE Link) te garantizas unas conexiones de cobre muy buenas. Sin ir más lejos, unos cables crimpadoshace años, y para mi decentes , no pasaba el test de velocidad de los 80 - 110 Mpbs...ha sido cambiar solo los conectores RJ45 y casi 400 Mpbs...con esto está todo dicho. No soy profesional de la materia, pero si te puedes permitir gastarte este dinero, te ahorras dolores de cabeza, conexiones que siempre te van a funcionar y como puedes apurar la longitud mínima del cable, puedes ganar en perdidas de conexión que con una crimpadora estándar no puedes. Si me la tuviera que comprar, no lo dudaría lo más mínimo. Muy contento con la compra.

Disclaimer: Ich verwende dieses Werkzeug nicht professionell. Für den Aufbau meines Heimnetzwerks musste ich einige Lan-Kabel verlegen und wollte sie aber in der Richtigen Länge haben. Ich habe vom Hausbau meiner Eltern noch eine Crimpzange für Hirose-Stecker übrig, aber keine Stecker mehr gehabt. Bei meiner suche nach neuen RJ45-Steckern habe ich gesehen, dass es mittlerweile Passthroug Stecker gibt, die ich noch nie genutzt oder gekannt hatte. Ich wollte dem ganzen mal eine Chance geben, vor allem weil ich mich noch daran erinnere, wie aufwendig die Hirose stecker, selbst mit Einfädelhilfe zu konfektionieren waren. Ich würde jedem empfehlen sich auf YouTube ein Paar Anleitungen anzuschauen, weil ich am Anfang Probleme hatte und schon die Passthrough methode aufgeben wollte. Nachdem ich aber den Dreh raus hatte, muss ich wirklich sagen, dass die Passthrough Stecker genial sind. Noch genialer ist das Werkzeug von Klein-Tools. Es ist zwar teurer als Konkurenten (bspw. VCE) aber alleine, dass man damit abmantel, schneiden und crimpen kann, macht es wieder gut. Weiterer Bonus: die Stecker-Belegung ist mit abgebildet, sodass man nicht erst umständlich im Internet suchen muss. Die Klingen schneiden den Kabelüberstand exakt bündig zum Steckerhäuse ab, sodass man auch keine Angst vor Kurzschlüssen haben muss. Klare Empfehlung!
