Only takes about half the power as a normal crimper. Has helped me tremendously. Easy to use. Built well. I will buy another if I ever wear these out.

like anything i was 50/50 on the purchase i usually like a hands on before purchase but upon receiving them i was ok with the purchase use them 2 to 3 time a week. there good and sturdy they don’t wobble and mess up the crimp. the only thing that’s a little bit time consuming is when your changing dies you have to fully remove a screw on both side and then re align the new dies in the jaws before tightening up the screws. plus side they do send two extra screws with it and a very clear diagram for all the dies in the set

Bought: Haisstronica 6PCS Crimping Tool Set Ok, Like many of you I have been using those cheap thin metal striper/crimpers that come in every electrical "kit" you ever buy. You can also buy those in stores and are fairly inexpensive, sometimes downright cheap. And to use them to crimp anything means hurting your hand from the pressure and that crappy thin metal. On to this tool and set: I paid $54.99 for this item and at time of review some 10 months later it is $49.99. That seems excessive or expensive however you know the old saying, you get what you pay for. Here you get so much more. It this set you get the crimping tool and 6 sets of dies. It says 6ps because die A is installed on the tool during arrival. The case it comes in is fairly cheap plastic but is more than enough for what you need. However I think the snaps that close it are poor. They are the standard molded on snaps that come with most things that wear over time and break and since they are molded on you cannot replace them. That's really the only con to this set. I opted for this set and not the one that comes with a screw driver because who doesn't already have a screwdriver in their tool kit? Anyways, the Tool feels great in the hand is VERY confrontable. The handle is molded plastic with rubber grips. Crimping pressure (how far down it crimps) is adjustable. The crimper uses a ratchet method so you don't accidently slip. This also lets you increase hand pressure a little at a time which is wonderful. When you hit the full crimp pressure the tool automatically unlocks releasing pressure. If in the event you cannot get full pressure to release there is a bar latch in-between the handles you can use to release the ratchet tension. The dies that it comes with are very wide for an even and professional crimp every time. Those cheap crimpers you get other places only crimp in a tiny spot which means sometimes you have to crimp then connector twice or more! Not with this tool, once and done! Changing dies is extremely easy. Just use a Philipps head screwdriver to remove two screws, one on the top die and one on the bottom. then change dies and replace screws. in the event you lose a screw, this set comes with two EXTRA screws! How awesome is that? This set also comes with almost every die you will need. I mostly use Insulated connecters so I mainly use die A but sometimes use others. I thought I'd never use the Solar connector Die but just recently actually used it and it worked wonderfully! Incase you forget what die is used for what, this little kit comes with a card with pictures of every die and the types of connecters each die is used for and wire sizes. that is EXTREAMLY helpful. The dies are each labeled A,B,C, ext. Also the case which holds the dies is also labeled in each slot for A,B,C, ext. So there is no confusing where each die goes or what they are used for. In conclusion, this set is well worth the money paid for it and is extremely helpful and comfortable to use. Not only that but it gives a good solid professional crimp every time. I have used this set hundreds of times. I have also installed 2 stereos in 2 different cars using this set and it was such a great tool to use. It not only made the job easier but it also made the job more solid and reliable. So please do yourself a favor and get this set, you will not regret it!

This thing works well. It is big and heavy but does a great job

Fantastic buy. I purchased this to crimp a variety of cable terminals for a commercial audio installation. I could not be happier with the purchase. It did an excellent job crimping. If you are looking at this because you have a specific job in mind, make sure the dies work with the terminals you intend to use. I needed only two of the included dies, but both worked perfectly. I am happy to have the other dies from r use in the future.

Better quality than I expected for such a low price. Have used insulated and uninsulated crimpers from Klein before, no noticeable difference in results with these for insulated and uninsulated butt connectors and ring terminals, MC4 terminals and Anderson Powerpole connectors. Swapping jaws is easy and they give you a couple of extra screws for the dies in case you drop one somewhere. Very good value and very impressed, hard to beat for a DIY user.

I bought this to make new wires with MC4 connectors from my solar array to the MPPT. It worked great and absolutely no issues. Crimps created are solid and fully crushed. Maybe worth mentioning is that for my installation, I wasn't using "solar" wire but 10 AWG marine grade wire from Ancor (also bought here when it was on sale). As already mentioned, it worked great for me as a home tool. I have no idea about the longevity of the item though if it were in constant / consistent use. For my purposes and cost for this tool though, I am 100% satisfied.

I've collected a bunch of different crimpers, but these are so nice I've been using these the most on my classic car rewire. Insulated or noninsulated options. Great product. Hasstronics has proven to make good quality connectors and tools.

Nice tools if you fix wire of your bike...

Buen producto, lo volveria a comprar

I've used this crimper on 3 different jobs now the latest one being a setup for a portable winch. Every single crimp has been good and solid, some reviews stated that these did not make tight enough crimps, this has not been my experience. Although I have not used all the attachments, out of the 2 different attachments I used both times the crimps made were tight. It's a much better tool than the cheap hardware store crimpers and an absolute necessity if you're dealing with different types of wire sizes and connector types. Super happy with it. A great investment for anyone who is doing wiring regularly.

Premiers tests très concluants sur les cosses isolées. Mâchoires "B" Dommage qu'il est necessaire d'utiliser un tournevis pour le changement des mâchoires. Mais ces modèles sont plus chers.

Great tool. Very please with the item. A firm and sturdy tool. Would recommend.
