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

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.

Klein Tools are always solid, and the VDV226-110 is no exception. As an IT professional, these crimpers have been great. They make quick work of cables, and the results are consistent and clean. I highly recommend pairing them with the Klein Tools VDV110-261. Together, they streamline the process and save a lot of time when you are terminating multiple runs. They are easy to use, feel durable in the hand, and perform exactly as expected. Another dependable product from Klein.

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.

I might still be making up cables for a living if I had found this earlier. I'm 65, with some old gnarly fingers that don't like to do precise work anymore. I've made up about a million (my hands thinks so anyway) rj45 T568B connections. My old crimpers required stripping the outer jacket back, untwisting the wires, then holding them together in a very specific color pattern, trimming them square at just the right length, sliding the 45 connector on and then crimping. If a wire didn't align just right and "jumped" a slot...you cut it off and started over. This crimper starts out the same, strip the jacket, untwist the wires, but then... it's different. You fit each wire in THROUGH the pass through RJ45 connector. This gives you the chance to check the color code mapping BEFORE you crimp and waste a connector. Once your sure the wires are "slotted" correctly, just give them a good tug to make sure they're seated , slide the connector in the tool and squeeze. It trims the wires off flush with the end of the connector, and presses the strain relief into place. The crimps are dead on accurate and the ratcheting mechanism gives you much needed leverage making for easier crimps with less fatigue over traditional crimpers. Awesome value, and a quality tool. Plus, it's more compact and fits in my tool bag easier.

Works right away, cuts all wires when crimping, and everything fits and comes together flush when crimping. My workplace had some other knockoff brands that would not cut all the wires are were not closing properly. If you're worried about the quality of your cables, this is the right one to use.

Comprei vários alicates da China e nacional mais esse devido o preço poderia vim melhor ele com 2 meses começou a criar a ferrugem nos lados e a lâmina de corte criou também de 1 a 10 eu daria um 7

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

I’m really impressed with this Klein pass-thru crimp tool. Before getting it, at least 1 in 3 of the cables I made would either not work at all or wouldn’t run at full speed, which was frustrating and a waste of time. Since switching to this tool, every cable I’ve made has come out clean and reliable, so it’s already saved me both time and money. I also like that it’s basically an all-in-one tool, which makes things so much easier when I’m up ladders or working in tight spots. It feels solid in the hand, the ratcheting action is smooth, and the pass-thru design makes setup straightforward. Overall, a great, dependable crimper that has made my cable jobs much more efficient.

Great quality but stripper does not fit properly

This gives users the ease to repair or terminate cables at desired length, great product
