ENGINEER Precision Universal Crimping Tool with Inter-Changeable die Plates (Size S) Handy Crimp Tool. Made in Japan. pad-11

Wow. Just wow. I bought a these PAD-11 crimpers to work with TH025 tabs and sockets in automotive work. The crimpers even came with to-the-point instructions on the packaging. The TH025 measure exactly 1.5 mm on the crimp wings when parallel. Engineer's instructions say to use the next size up, which would be 1.6, and best results are with the crimping wings parallel to each other. Included are diagrams for good and bad wing alignment with the tool die.My first crimp turned out perfect! It looks factory, and is secure. That is all I wanted, and I got it. So glad I didn't cheap out on one of the many other ratcheting tools that claim to do both insulation and wire crimp simultaneously. For small projects, this is fine to do the two parts separately, and allows you to verify the wire won't pull out before you crimp the insulation.If you need anything more than this, you'll have to graduate to the industrial tools costing hundreds or more.The wire cutter is sharp and the stripping notch is handy. There's also a convenient rule printed on the side to measure something up to 10mm. The orange handles are not cheap plastic, but some sort of soft elastomeric grip.I'd add a photo, but the TH025 crimps are only 1.5mm wide, so hard to photograph without my pro gear set up.

The good:Feels solid and well balanced.Interchangeable dies means you don't have to buy a whole new tool to occasionally crimp and uncommon size.Hinge action is super smooth and has no side-to-side wobble.Perfectly aligned dies.The bad:The grips take a little getting used to, still feels a little weird in my hand.Other thoughts:They were more costly than the usual bundled fare you find in "all-in-one" combo boxes of connectors / wires / tools, and I was a little curious as to whether or not I would actually see enough difference to make up that price. As you can tell from the above, I did. These have a much smoother overall finish, better action, and the dies worked great on mine without any adjustment or alignment needed. The wiring on my Arduino projects goes faster than ever.

If you been crimping connector for any amount of time you probably have several style crimpers. These are categorized in your head based on performance with a given sized crimp. Well, all of them seem to have little issues that for whatever create a less than ideal crimp, maybe they flatten the crimp too much & make it arch, thus having to straighten the crimp out after crimping. Possibly, the crimper die is slightly mis-cut on the 1.6mm crimp & 2 outta 4 times it'll break the right tang off the crimp body.I've been crimping a wiring harness for a flight controller, servos, balance connectors, etc. & so far this crimper has produced the closest thing to a perfect crimp.One drawback! There is a wire cutter section right next to the hand grips & if you're not careful you could easily crimp & cut the a fatty pad off of you palm. I'm about to grind off the cutter all together but just be aware of it.It's not the perfect crimper but it can produce perfect crimps.

These tools work on extremely small parts and require you to get a "feel" of the work. Don't expect it to work the first time. Very precise tool.

The die blades are a bit on the thin side. It may be good for certain connectors but some of my connectors required more than one crimp on the conductor side.

I bought this (No. 11 die) based on various online reviews recommending it for JST-GH crimping (Genuine SSHL-002T-P0.2 contacts) as an alternative to JST’s expensive tooling.The die slots were physically small enough to crimp these tiny contacts, however the resulting crimps are completely unusable. Conductor crimping was alright and passed pull testing, however the contact is slightly bent during the process which sets you up for failure crimping the insulation and inserting it into the GH housing - something a lot of 3rd party crimpers suffer from. No die could crimp the insulation. Too large of die and you can’t insert it into the housing, and too small of die breaks the contact, no nice middle ground.I believe someone else had the same experience and returned their tool because I received the tool with its packaging already opened with no attempt at making it look new again, and there was usage marks at the pivot joint and cutting blades. This is Amazon’s fault not Engineer’s, and the tool quality seems to be pretty nice.

Took a small amount of practice, but now perfect crimps every time, even tiny crimps. Solid tool!

Good for crimping down to 1.25mm pitch pins.Most of my use is for Molex Pico-SPOX pins (1.5mm) and with this tool I get very consistent results.

These precision machined and well polished dies have sensible spread between sizes so you can always get a good crimp on any terminal within range of this tool. The smallest size is distal to the fulcrum so you can really feel how much pressure you are exerting. I do have a couple of similar but cheaper tools from IWISS and but the smaller terminals are so tiny that it can be difficult to align them into the tool while crimping and the PAD-11 is so well machined that the whole process just becomes easier. This is the one I should have bought in the first place for my 2 step crimping tasks. I also purchased the bigger PAD-13 so that I can also do the bigger contacts found in appliances and so on. Having both is much better than swapping dies all the time.

Habe diese Zange für die JST-SH bestellt. Funktioniert super mit ein bischen übung. JST-XH und PH gehen auch.

Il faut savoir investir parfois, et pour sertir des connecteurs, même de façon anecdotique, je pense qu'il faut casser sa tirelire et acheter ce genre de pince : sertir des duponts ou autres devient un jeu d'enfant.Pince de bonne facture qui plus est, et solide.*Possibilité de changer les mors si on veut sertir plus gros.

La mejor crimpadora que ha caído en mis manos. No pierdas tiempo y dinero con otras.
