I received the tool in a very good and safe package and on time. TEMCO provides great tools and equipment. Excellent crimping tool, very easy to work with and stable when using the Hammer. I strongly recommend ths vendor for future orders.

This crimper works great on 4awg ring terminals. It works best if you mount it to something for a more stable base. I ended up bolting it to a piece of 3/4" ABS plastic. At first I screwed it down to a 2x4 that ended up splitting in half after a couple of crimps. 1 or 2 good wacks with a 2 pound hammer works well. Very happy with this tool. It does the job. The only drawback is, you need a good solid working surface close by. Could be an issue if you are terminating short wires inside a panel

Did the job. Made the job easy, simple, and effective. The crimping accuracy and strength of the lug is all on you. The tool is the perfect size and it seems durable.

As a lug crimping tool, this does the job, and not only that, the crimps hold really well. That goes to say, assuming the end user is using heat shrink for every lug as well as proper wire stripping methods. The tool is very straightforward, easy to use, and will take the abuse.The crimp will hold the wire and lug together tight, but the style of crimp can still fail, due to it being crushed or hammered down on one side, compared to other crimpers which squeezes the entire lug. Its also a little difficult to hold the wire inside the lug before hammering the tool. Other than that, this is a great product.I would recommend to beginners and others who seldom do wiring, however I would suggest solder methods or better lug crimpers for the everyday electrician

For a better grip, you may want to try this great little Gizmo. When crimped, it's there to stay.

Bought this to make my own cables for an RV wiring upgrade. Worth every penny. It's smaller than you'd expect, but quite tough. I've made multiple cables using 4/0 welding wire, 2 awg welding wire, 1awg thhn and 6 awg stranded wire. This crimper handled them all perfectly. Pro tips: Use good copper lugs appropriate for the gauge wire you're crimping. Find a firm surface, concrete or steel will do. Use a small sledge, 2-4 lbs, but one that you can still operate comfortably with one hand. Hold the lug snug to the wire with one hand and hammer with the other hand, at least for the first tap or two. Start with a decent tap, just to seat the crimper in the lug so when you whack it with the next strikes it won't slip. 4-5 good whacks (for 4/0, less for small wire), you'll hear the sound change as you compact that wire and turn it into essentially solid metal at the crimp. When that sound changes, you're crimped! No adjustments needed between different wire sizes, it's self adjusting. I also added solder to my connections. I found this worked best: flux the copper wire and the inside of the lug beforehand, then crimp as described, then heat it up and add solder (some of my larger lugs had no holes in the lug, other than the big one the wire goes in, so I drilled a 1/8" or so hole in the lug to add the solder thru. Worked great, but honestly, you don't even need to solder these connections. The crimper makes them that strong! Recommend heat shrink wrap, the good thick kind with glue inside. Strengthens the connections, makes it waterproof and looks professional

I wanted to re-wire new batteries to the bow thruster and windlass on our sailing boat. Getting an electrician to show up and do everything was going to be tricky and, in the end, proved impossible. However, I purchased this crimper tool in advance and it allowed me to do all the connections on the marine grade cables, from AWG 6 through 1/0 without a problem. I did borrow the industrial shipyard vise to help me push the crimper (along with a hefty pipe I found on the floor for extra torque); but this tool did everything with ease. I lost count of all the connections, easily over 15 with cables of all sizes and high quality (thick) copper connectors.It's a big recommendation from me.
