iCrimp Heavy Duty Copper Lug Crimping Tool, for AWG 8,6,4,2,1 Gauge Battery Cable Ring Terminal Ends with Built-in Cable Cutter

I learned about this product on Will Prowse's YouTube channel. It's way better than I expected it to be. Makes great crimps, if a bit narrow, but there's room for two crimps on most lugs. I use it with UL-listed lugs and have gotten consistently good results. It's a convenient size, works exactly as it should, and is a great value. Definitely five stars. If you are considering any of the inexpensive hydraulic options for lugs in this size range, do yourself a favor and buy this instead. I have bought two of them and they are just low-quality crap by comparison, with one lasting exactly two crimps before failing. This thing is way better and easier, and therefore faster, to use.

I used these to put lugs on 8 gauge marine wiring. They worked great!! These are heavy duty. Highly recommend!! The lugs I used were 2 different size but this brand. https://www.amazon.com/dp/B000NI5D06?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1

If you are doing battery or speaker/amp connections once every 3-5 years then you absolutely do not need a different tool. This gives very decent hex crimps, and it cuts fairly well. The grips are solid, it takes a bit of force to properly do it, and you might want to practice on a lug or two. I don't see any reasons so far to give it less than 5 stars. It's not something made by Snap-on, but you are paying a very small price compared to what they would charge. I didn't even look to see if they had a hand tool like this honestly, but it would be 200+ easily. Obviously, if you do this for a living you have a hydraulic tool of higher quality. BUT this thing is incredibly useful. For anything in that 4-8 gauge range it is nearly perfect. We'll see if it holds up. As another reviewer said, I prefer this to any of the separate die tools that are not hydraulic just for ease of use. If I did any of this for a living I'd have a high-end hydraulic crimper.

Feels solid. Gauge marking don’t seem that accurate but easy enough to just use the next smaller size. Probably has to do with all the variances between actual wire gauge, lug quality and the cheap tools. Either way, they got the job done with no worries about the tool falling apart.

Again another great tool for my automotive electrical work. Ready to perform

Great tool. Skip the IWISS ratcheting crimper and get this. I bought both this and the ratcheting crimper to compare. The ratchet is much easier to use, but gets just "OK" results. This thing does a proper hex crimp that's quite uniform all the way around. The ratcheting version kind of mashes the connector flat-ish, especially if you do two hits (which I think you should). I've attached some pictures (black wire). I've been crimping dozens of heavy lugs (no insulation) onto marine grade 6AWG cable for solar battery bank. This is my go-to crimper now for big lugs. The ratchet is being returned. Only two minor complaints: 1) it leaves a bit of a "shark fin" on both sides of the crimp - basically where the jaws come together. It's not bad and looks fine with heatshrink over it. 2) you need 3 hands to operate it. my method is to load the lug into the jaws, come down lightly on it, then place the crimper on its side on a sturdy workbench (one handle resting on the bench), insert the wire and press down on the top handle. Once the lug has a grip, pick the whole mess up and finish it with both hands. Excellent, predictable performance at a very good price.

After looking at a lot of battery cable crimpers I chose this one because I liked the design and that it gives a hex crimp around the lug, also has a cable cutter on the end which cut the cable with no trouble. It works well and put a good crimp on the lug for me. Shipped in one day.

I used this to crimp 6 gauge battery lugs and connectors when installing trolling motor wiring in my boat. These are excellent. Crimps are nice and tight. No fiddling with size wheels or dies. It already has the cable cutter as part of the tool. Very handy, easy to use, marked with actual gauge sizes not MM and having to use conversion chart. I returned a KOTTO Battery Cable Lug Crimper Tool 6-50mm² combo, it was junk. It would not crimp tight enough for the corresponding mm conversion. I was thrilled to see how well this IWISS one worked. Even though the crimps were already nice and tight, I noticed that this product also has the ability to make small adjustments if needed. The default settings gave excellent results right out of the box.
