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.

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.

Great buy for the price. Does just what I needed. Comfortable grip, great clean crimps, perfect addition to my electrical repair tools.

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.

When I saw this set, I knew I had to test it and try it out for myself. Especially since I am always working around automotive wiring and connectors. The crimping is good since it has enough different types of style crimping blocks, and it comes with a nice case. The color of the handles makes it pretty easy to spot and find when looking for it. It has clicking so has a good way of crimping down and you know when to stop, and it's not hard to use.

Bought about 2 years ago. Uses constantly no symptoms of failing just yet

Seeing as how a good quality crimper runs anywhere from $75-$200+ dollars, my expectation for this 5 in 1 for under $50 was not very high. I received it packaged quite well, and it came with a cd holder type case that has 4 pouches for the extra dies, a screwdriver with its own straps, and a spot with elastic and velcro straps for the actual crimper. Being an Industrial Electrician, this is a tool that I need quite often, since I am one who likes to ferrule and ring the ends of 98% of the wires I terminate. Having had carpal tunnel surrgery, a tool that uses mechanical action and leverage to its advantage to increase ease of use is right up my alley. So once I took it out of the case I tried out every die that came with it; I put in every one and crimped a few wires to see how it actually worked. Besides the alignment of the dies when the tool is completely closed being off by like 1/16th inch (which did not seem to affect the crimp at all) this tool crimps all 5 different styles nice and secure to the wire, and actually doesn't leave that bad of an actual crimp on them either. It does not crimp ferrules into modular shape (square) like a lot of the pricier ones do but it does crimp it on securely and gives almost like a U shape to the ferrule. Overall for not having that high of expectations to begin with and for being less than $50, this is a great product. It is made in Japan but it is quality made and if take care of and used properly should last hopefully a few years an up. Great product for the price!

These seem to be of very high quality. But, using the color coding, almost every crimp I make with it, is not near tight enough. And once you start closing it, you are committed. Because of the ratcheting mechanism, once you start crimping, you cannot open them back up until you close them all the way. So you cannot reposition once you start. I wanted to love these, but they mostly lay unused in my toolbox. The strippers work well, and the case is nice

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.

Good quality

This is a great set, one complaint is that the only the die it comes loaded with has the wire gauge marked on it, the rest don't. Not a huge deal as you can dry fit your crimp first but it would have been better if they were stamped with the wire gauge size.

Good
