Review on 🛠️ IWISS Ratchet Wire Crimping Tool Kit with 5 Interchangeable Jaws, Wire Stripper and Cutter for Insulated and Non-Insulated Terminals 0.5-35mm ² in Oxford Bag Packaging by Jay Huang

My only regret is not purchasing this set sooner. At my place of work I had to constantly use tools to squeeze the Delphi weather bag/Metripack. Terminals and the crimping tools I used were extremely simple, ratchetless types. This made crimping the terminals quite time consuming as I had to hold the wire and terminal together while installing the tool and crimping it. I finally gave in and bought this set. To say it made my life easier is an understatement. The ratchet mechanism and large handles make crimping a breeze - simply place the terminal and turn the ratchet until it grips the terminal, feed the wire through, then squeeze the handles. You'll get the right crimp that sits where you want it when the jaws are released without putting extra strain on your hands. The stripping tool is very decent. Massive handles, a light spring and a sharp edge make it easy to remove insulation, and the lock is very convenient for storage. Note that the A03BC terminal set is designed for terminal-to-wire termination on Delphi Metripack/Weatherpack connectors, but does not have a dedicated jaw for "crimping" the rubber seal at the end of the terminal (which provides a perfect round crimp jaw required ). The figure shows only a crimped wire interface with an uncrimped gasket. However, I found the A10 10AWG hole worked pretty well. I have not tested other crimping dies but will update this review if necessary. Overall, I highly recommend this tool. It looks like a quality part for something this cheap and it really made the hookup process fun and relaxing. Usually these things are junk because they never crimp properly and I think most people just solder them. However, today I crimped them with A30J dies and the results were fantastic. While it doesn't give the square pressure that dedicated crimping machines would, the crimp was strong enough that I couldn't pull the wire back out; The plastic insulation was also shaped so that the end would "grip" the wire properly. If anything, it was even more impressive than the Metripack ferrules I've made in the past.
