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

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

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!

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.

I crimp crimping tool. Havn’t used but it look’s good.

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