iCrimp Battery Cable Lug Crimping Tool for Open Barrel Lug,Lead-Free OEM Battery Terminals,B Type Crimper for AWG 13-3

The IWISS IWS-5100A crimping tool is built like a tank!The handles are made of thick steel, the grips are large, non-slip and comfortable. The crimping head is 9mm (almost 3/8 inch) thick steel with the crimp patterns wire EDM machined into it.The long handles and the pivot design provides great mechanical advantage - crimping thick, heavy connectors is effortless.Although this is not a "ratcheting" crimper, the mechanism goes slightly "over center" so that it's impossible to make a faulty crimp by not squeezing enough.The crimp patterns machined into the head are shiny smooth and don't leave any gouges or burrs on the connector.The crimp amount or depth (squeeze) is adjustable by loosening two locknuts and then adjusting the two pivot cams. There are 4 settings on each cam, so you actually get 8 different settings.The crimper comes set to 1,1 which is the lowest setting. At this setting, the crimps are perfect. The adjustment cams have a hexagonal lock under each head so that they stay where they are set. It is impossible for them to self-rotate out of adjustment.Maybe after years of use, the tool might wear enough to require adjustment, but since it's so heavily built, I doubt it would ever wear out in my lifetime.I own several different Iwiss brand crimping tools and they are all very good quality and work flawlessly. This tool is no exception. It's super easy to use, it's built very solidly and it makes beautiful, strong crimps. Also, unlike other brands, this tool was lubricated during assembly as evidenced by traces of oil on all the joint pivots. A little thing, but it's another indicator of Iwiss quality.This tool is a bit expensive, but you get what you pay for and more.I give the IWISS IWS-5100A crimping tool both thumbs up!

This review is for the 5100A, I needed a crimp tool that would handle larger diameter splices. The first slot (A) works very well with AMP (TE) 8500-1400 CMA crimp splices. Perfect for making power or ground branches in motorsport harnesses on a budget without sacrificing crimp quality. The quality of this tool is actually better than some of my GM Delphi and Sargent crimpers. There is very little slop in the tool and the jaws are well made and smoothed. Another review saying it "was built like a tank" was correct. I have a few iCrimp tools from Amazon and have been very pleased.

I bought a box/set of open barrel copper connectors and found I couldn't make any of them work without the proper crimp tool. So, I purchased this one. Once I received it, I did a few experiments on crimping various gauge wire with the various open barrel connectors. It's good to practice with this on junk wire so that when it comes time for the real deal, you're prepared and will do a correct crimping job. I can say that I'm totally happy with it. It's a very well built set of crimpers. The prime reason I gave it four stars for "Easy to use" rating was/is because in a situation like crimping, you need two hands for operation of the crimpers. Then you need another hand to place and hold the connector in place in the teeth of the crimper, and finally you need another hand to hold the wire to be crimped so it's properly placed in the open barrel while the two handles are being squeezed together. For this very reason, I would have liked to purchase the bench unit but, the ones I bought are more versatile and portable.On edit: The bench unit basically takes the place of a couple extra hands. Now, primarily you need only use one hand for the one handle since the base of the unit is stable. And you can use the other hand for stabilizing the barrel connector and the wire end that are in the jaws ready to be crimped. But the bench unit is not nearly as portable as the two handled one is so, working close to your work and not a bench means you more that likely need the portable unit.

My first crimp is shown in the photo. The crimp is mostly ok, but you can see the crimper wasn't placed quite close enough to the ring and required a second crimp to touch it up nicely. That was just my inexperience with the tool. A dozen crimps later I am producing excellent results with minimal fussing around.The tool itself is extremely sturdy and easy to work with. That said, even with the compound action design and long handles it does take considerable effort to crimp the 50A and larger size barrels. For those I put one handle against the floor and use my arms and a little body weight to squeeze down the other crimper handle and complete the job. Once you do it a few times it is simple.The cutter works easily and the nose of the crimper can be used to tighten the barrels on the crimps before inserting into the tool (you have to do this with the crimps I have).I have no regrets about the price or quality of this tool so far and I no longer dread crimping larger terminals or worrying if they are crimped properly. Should have gotten this long ago.

Seems to be solid tool

I have purchased 2 of these, one for each of our work locations, they are great! I can do splices of 5-20x 20ga wires together with either closed or open barrel crimps with no problem, join 1x 12ga to 6x 16ga with a 8ga crimp with ease, its awesome! I have a 2nd crimper, one of the Themco hydraulic ones but i only use that for much larger 0, 1, 2 or 4ga wire, but this does 90% of my main day to day. Highly recommended, great quality and super sturdy.

Both the battery terminals on my NA Miata were broken enough it was hard to get a good connection to the battery when I bought it. They are attached with this style crimp. Bought this tool and some new terminals. The hardest part was probably getting the old ones off without making the wires too short. Tool worked perfectly. I don't have a ton of strength but was able to easily crimp them both using it.

These work awesome. Very easy to use. Just make sure to purchase the right wiring terminals. These actually performed better then expected. Makes wiring look profession. Well made also. Highly recommended.

Good product and good value for money. Used professionally, functions well.

Works great for larger open barrel F-splices (Amp/Tyco/TE).
