iCrimp Ratchet Wire Crimping Tool Set w/ 5 Interchangeable Jaws

I have been using this kit constantly. Crimp tightness is great. The rachet mechanism is crisp and reliable. Super easy to use. The included dies get most jobs done. I crimp a lot of coax connectors, so I had to get a die for that, but since this uses standard die mounting (2 screws) there were no issues at all. I think since getting this I have used it over 100 times. It has become part of the toolbox and not set to the side. Crimps properly and reliably every time. Really happy with this purchase.

My only regret is that I didn't buy this set sooner. At my workplace I had to constantly borrow tools in order to crimp Delphi weatherpack/metripack style terminals, and the crimp tools that I used were extremely basic non-ratcheting types. This made it fairly time consuming to crimp terminals because I had to essentially hold the wire and the terminal together while positioning the tool and crimping it. I finally caved and bought this set. To say that it made my life easier is an understatement. The ratchet action and big handles makes it trivial to get a proper crimp- simply place the terminal and ratchet until it holds the terminal in place, slip the wire through and then squeeze the handles. You get a proper crimp that is positioned where you want it when the jaws release, and it places no additional stress on your hands. The wire strippers are very decent. Chunky handles, a light spring and sharp edge makes it fairly easy to strip insulation, and the lock is pretty handy for storage. Keep in mind that the A03BC jaw set works for the terminal to wire connection on Delphi metripack/weatherpack connectors, however there is no specific jaw for 'crimping' the rubber seal at the end of the terminal (which requires a perfectly round crimp jaw). The picture shows just the wire interface crimped with the seal uncrimped. I found the A10 10AWG hole to work well enough however. I have not tested any of the other crimp jaws but will update this review if required. Overall, I highly recommend this tool. It feels like a quality piece for something so inexpensive, and it actually made the experience of wiring actually fun and relaxing. EDIT 8/10/2017: I used this crimper with the cheap red/blue/yellow terminals. Usually these things are junk because they never crimp properly- and I think most people simply solder them. However, I crimped them with this today using the A30J jaws and the results were fantastic. While this doesn't make the square imprint that specialty crimpers would have, the crimp was strong enough that I couldn't pull the wire back out; the plastic insulation was also shaped so that the end 'cupped' the wire properly. If anything, this was even more impressive than the Metripack crimps I did earlier.

It works as it should very versatile with the interchangeable jaws for all kinds of terminals

I was looking for a crimper that was a step above the plier style or those you find in a cheap kit and also needed one that would work with ferrules. This iWiss crimper with interchangeable jaws fit the bill and was at an attractive price point. I've used the crimper for both heat shrink butt connectors, small lugs and ferrules. It has done a fine job with each. The crimper does have a force adjustment and I did end up increasing the crimp strength and the resulting crimps have all been solid. Jaws seem reasonably well made and align well with the tool. Swapping out the jaws is just a bit tedious with the screws, but not bad. The case is a nice touch, although it was not made to hold the wire stripper that came with the kit, it just sits inside while the crimper and screwdriver have elastic bands and velcro to hold them in the case. The insulated crimp jaws (red, blue, yellow) do work well with both standard insulated and heat shrink terminals. The ferrule crimper doesn't create a perfect square, but does work well on the sizes I have tried. I have not used the other heads yet, but they all appear to be well made. If you are a professional that uses them daily, maybe you want a better tool, but for most DIY people or for a backup it is hard to go wrong with these.

The fit and finish are good. The soft case is a nice added option. it does hold all 3 tools and the jaws. It is made of very thick material and the zipper is quite heavy duty. The strippers are nicely machined and very sharp. The jaws line up and the stripping action is very good. The crimpers are also very well made and the ratchet movement is precise and even. All but one of the jaw sets are symmetrical. The miss-ground jaw set isn't 100% useless. It is used on non-insulated terminals; which I use very infrequently. The screwdriver feels cheap in the hand, but it has only one function. To change out crimping jaws. If it is only used for that task it should be fine. This is not a commercial grade crimping set, but for the amount of uses I will put it into service it should last me for years. UPDATE: I had a jaw that was not drilled correctly. Contacted Amazon and again Amazon took care of the issue in less than 3 days! 100% satisfied with the seller, Amazon & the crimping set!

First caveat - I bought this simply for crimping uninsulated spade terminals on 18ga wire, which I needed to do several hundred of, so I cannot speak to its durability crimping large connectors. I had previously purchased, on Amazon, on of the sets of “hundreds of crimp connectors with free crimping tool”, and found that the crimp tool was garbage. Instead of rounding the tabs of the spade connectors down over the cable, it simply smashed the tabs down, which often broke them, or didn’t grip the wire. Further, all the connector/tool sets seem to give you the same $10 crimp tool, so stay away from all of them. The crimp sets in this kit are not as finely machined on the outside as others, but the interior profiles, which actually contact the connectors, are machined in better detail and work far better. After throwing away the other crimp tool, I was able to work almost twice as fast with this tool, and with zero wasted/broken connectors. I did look at more expensive crimp tools, and believe this set to be the “Elbow of the curve” - it works well at a very reasonable price, and to do noticeably better, you will need to spend significantly more money. Highly recommended kit.

The iCrimp crimpers and wire strippers have held up very well with repeated use, and the quality of the W crimps has been impressive. I have bought three sets of these so far, one for each of the training schools I support and one for myself.

Don't waste your money. My 50 year old JC Penney crimpers do a better crimp. The jaws for AWG wire sizes up 10 awg work mostly for insulated ring lugs. For non- insulated ring lugs or butt splices either insulated or non-insulated there are no jaws that produce proper crimp. The jaws for non- insulated lugs has a picture of a ferrel. There are no jaws that take lugs for 2 awg as advertised. I would return but it will cost more in gas to get to the UPS store. 9/18/2026 update: raised to 3 stars after messing around with the connector types I use. 1. Terminal lugs, ring lugs etc. you must insert the wire from the left. This applies to both insulated and non - insulated. AWG 22-18 crimps are marginal 2. Butt splices, wire must be inserted from the right after careful positioning. Again AWG 22-18 are marginal. Other sizes up to 8 AWG are good and repeatable. 8 AWG are very hard to crimp, take your time. Careful positioning of butt splices will let you double crimp.

na jaar gebruik, nog steeds een goede tang. knijpt makkelijk

Muy buena calidad a precio asequible, lo he utilizado para ferrules, empalmes, conectores diversos y funciona muy bien. Hay que saber elegir los conectores para que no queden flojos y ver bien el lado del que se crimpan, hay que hacer una prueba para darse una idea de como va el conector.

Does the job quite well. As expected struggles a bit with heavy cables but with a short learning curve it delivers.

Good quality
