Best Crimpers of 2025

"I've been using the Klein Tools 3005CR crimper and it has significantly boosted my confidence in crimping two wires. I no longer worry about wires coming loose. The strip tool also provides a clean, straight cut, which is fantastic!"

"These crimpers have been a great asset for me as a diesel tech. I appreciate the crimp strength they offer for butt connections. However, they can be a bit bulky, making it challenging to fit into tight spots."

"This crimper has performed flawlessly with various connector types I've tried. The ratchet action feels satisfying, and it's very comfortable to use. Plus, I love the ability to release the crimp early if needed!"

"I've found that Klein makes exceptionally good tools. I added some shrink tube to the handles for a better grip, but that's just my personal choice."

"The quality of this tool is tremendous. It's well manufactured and incredibly durable."

"This tool works great for my needs. It cuts and crimps effortlessly on 10-22 AWG terminals, which has made my electrical projects so much easier. The quality is evident, and I appreciate that it's made in the USA."

"I had to terminate about 20 CAT6 ethernet lines and wanted a quality tool to make it easier. This tool has worked great for me! I’ve terminated 8 lines easily, and it cuts, strips, and crimps the connectors solidly. Highly recommended!"

"After using cheaper crimpers, this tool is a game-changer! The cutter and stripper work perfectly, and the crimper is flawless. A must-have for making cables!"

"I've been a fan of Klein Tools for a long time, and this one is no different. The pass-thru feature is fantastic for confirming wire order before crimping. I do wish the RJ-12 had this feature too, but the tool feels durable and well-built."

"I was initially 50/50 on this purchase, but after using it a few times each week, I'm satisfied. They are sturdy and don’t wobble during crimping. The only downside is that changing the dies requires completely removing screws, which is a bit tedious. However, they provide extra screws and a clear diagram for the dies."

"I bought the Haisstronica 6PCS Crimping Tool Set and have found it to be a significant upgrade from the cheap crimpers I've used before. The pressure adjustment and ratchet mechanism make crimping easy and reliable. Plus, the included die card is extremely helpful for identifying the right die for each job. This set is definitely worth the price!"

"This crimper has been a fantastic addition to my toolset. I’ve used it extensively for various jobs and have always achieved solid and professional results. Whether for insulated or non-insulated connectors, it has performed superbly. I highly recommend it to anyone who works with wiring regularly!"

"I absolutely love this tool. Stripping electrical wire or speaker cable can be a challenge with typical wire strippers, often leading to cutting too deep and severing the wire. I tried it on some leftover 16 AWG cable and it stripped the jacket effortlessly. When I moved to a thicker 12 AWG cable, it struggled initially, but after adjusting the knob, it worked perfectly. The cutting and crimping features are also excellent. Using this tool made the process quick and enjoyable, which is a refreshing change!"

"At my local dealership, I handle most of the electrical work, and these pliers are fantastic. The sideways serrations on the tips make removing fuses in tight spots easy. The wire strippers perform well for automotive applications, though I have to tilt them slightly for smaller gauge wires. One minor issue is that crimping can dig into my hand during extensive tasks. Also, the wire cutters are in a somewhat awkward position, but overall, I highly recommend these pliers for anyone's emergency tool kit!"

"Using these pliers for crimping is a game-changer. They work like bolt cutters, are easy to adjust for different sizes, and are well-made. Although I had to crimp multiple times for a clean finish initially, the durability and effectiveness made it worthwhile. If I had the chance to do it again, I might consider spending more for a hydraulic option, but for now, I'm satisfied with my purchase!"

"I can't believe products from GB are still getting bad reviews. Their tools are solid and awesome. I’m usually frugal, but I have no regrets about my GB purchases. The pliers have a nice grip, and the cutter works well."

"I’ve been using a terrible old crimping tool, but this one is a game changer. It has a great shape for a solid pinch. I only wish I had bought it sooner!"

"I’m really happy with my purchase. This tool feels substantial, and the crimps are precise. It's now an essential part of my wiring toolkit. I highly recommend it!"

"This tool is perfect for my tasks; I have nothing negative to say about it."

"For the first time, using this tool brought me so much joy. It feels like a top-notch professional tool. I did have to use the number 6 selection for an AWG 4 wire to get the best crimp, but everything else is top quality. Thanks, iCrimp!"

"I wanted to love these crimpers, but when I applied larger crimp pressure, the jaws shifted sideways, leaving the crimps not secured at all. Unfortunately, I can't use them."

"This is the number one tool for crimping; nothing else compares!"

"As someone in the tower telecom industry, these are a must-have! They're incredibly easy to use and offer the best value for my budget!"

"While they are a bit pricey, you get what you pay for. They provide a smooth crimp with excellent leverage, and I appreciate the comfortable handle for one or two-handed use. Although the plastic feels a little soft for construction, I'm still satisfied with my choice over the Greenlee."

"I found the crimper to be effective and it looks great with an easy-to-read dial gauge. Highly recommended!"

"This crimper really impressed me. I do my own wiring and have had issues with connectors before. I got this for a great price and it arrived the next day. The rubber grips made it much easier to use than my old one. I would definitely recommend it!"

"I always thought that only Klein crimpers were worth using, but this one has changed my mind. It’s cost-effective and more user-friendly than Klein crimpers. I’m really pleased with how it performs!"

"I regret not buying this set sooner. I used to struggle with basic crimp tools at work, but this ratchet action crimper made my life so much easier. It’s straightforward to use, and the wire strippers are decent too. Overall, I highly recommend this tool for anyone needing reliable crimping."

"As a 68-year-old woman with limited grip strength, I was pleasantly surprised by how easy it was to use this ratchet crimper. It came with various jaws, which were simple to switch out. My work turned out great, and I’m very pleased with my decision to buy this crimper."

"I was looking for a crimper that was an upgrade from the basic ones, and this iWiss crimper fit the bill perfectly. I've used it for heat shrink butt connectors and ferrules, and it performed exceptionally well. While changing the jaws is a bit tedious, the results are worth it. Great tool for DIY enthusiasts!"
