iCrimp Ratchet Wire Crimping Tool Set w/ 5 Interchangeable Jaws for Insulated and Non-Insulated Terminals AWG20-2, Wire Stripper included

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.

I bought the ratchet crimping tool to crimp ferule tubes on cable wire for my dc to power station charger. This particular charger does come with the cable kit but at the time the company was out and I didn't want to wait for restock. I am 68 year old woman with terrible hand grip so I was hoping I could handle the ratchet. Yes, I handled the ratchet quiet well. Because I had no experience or knowledge of how to go about it I was a little slow at first. I have to say the ratchet is very easy to use. It comes with different exchangeable size jaws that are easy to switch out. I am very impressed with this ratchet. My work looks good and the charger is up and running. I definitely would recommend. Because I am not a professional but a DIYer I looked at price as part of my decision making process, so glad I picked this one.

works well once you find the right die for the job. could be easier to change dies.

Quality tool. Jaws interchange easily. Adjustable ratchet for that perfect crimp.

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.

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.
