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

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.

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 tool is awesome! It's incredibly well built and worked perfectly for crimping new battery cable terminal clamps to replace the existing damaged ones. It does require a little setup time to properly set the cable in the new fitting the center it in the jaws but once done its a simple squeeze away from having a professional grade crimp.

Haven't had a chance to use the tool yet, but it seems sturdy and well built. Decent price. The only thing I see may be an issue is that the jaws could be a little wider. The crimp portion of most connectors are longer than the jaws are wide.

Omg, it was way more work than it should have been to see if these would work! As another reviewer said: the labels on the jaws are not helpful. Pictured is a new XScorpion brand 4-gauge terminal in the first (smallest) crimp slot on the 8200-model crimper. It fits perfectly. That is what we needed to know, not whatever Amp rating they were designed for.The black wire pictured was my first attempt/practice shot (wire length was not a concern) on vintage Stinger #4 ground cable. The two blue-wire crimps were on new tinned-copper Monster Car Audio (Monster Cable) 4-gauge. I left the silly "flux-tube" in there, as the wire-braid is wrapped around it. It's a Monster Cable feature.Look how clean those crimps turned out. I also lightly greased the tool's die saddle with Shell Gadus grease. After a total of four crimps, I can already feel minor slop developing in the main handle-pivot. I snugged the 13mm nylock nut, while holding the pin-head with some pliers (as I saw another person comment on). The jaws are nice and thick steel, but the handles are far too short for the amount of leverage required to crimp, at least with these nickel-plated "platinum" brass terminals. Copper terminals would probably be much easier. Still, for the price, this provided excellent results.I bought the 8200 because I wasn't sure if the #4 terminal would fit in the smallest die. The middle die is too large, so factor this in if you'll only do #4 and below (get the 5200 model instead). I also plan to crimp car battery terminals in the future, so I knew I'd need 2GA capability at some point.

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.

This is a quality piece of equipment. At this price, you could break after one repair and it would still pay for itself. Fortunately for us, this thing will last quite a long time.
