Review: Great crimping - An excellent crimp tool. Bought this to crimp the smaller JST Molex pins/connectors. These crimps have a narrower nose which is perfect for the small connectors. Crimps with a wider jaw will flatten the small tag that holds the connector in the housing. These work perfectly and produce a neat and tight crimp. Recommended..
Review: A Dupont cable crimping tool that really works and looks like it will be my go to crimp tool. - I had almost given up with finding an affordable, easy to use crimping tool, for Dupont plug and socket crimp connectors that provided a crimp as good as the mass produced breadboard jumper wires. If you can get good mass produced jumper wires why bother with a crimping tool, It all about length with longer wires you get problems with the way an electrical circuit will operate. So I like to use commercial jumper wires and tailor them to the length I need for each part of the breadboard circuit. The "WISS SN-2549 Crimping Tools for Dupont terminal 0.08-1.0 mm² XH2.54/ 2.54/2.8/3.0/3.96/4.8/KF2510/JST Terminal Crimper Plier Ratcheting Wire Connector Crimping Tool " has proved to be the best quality crimping tool to date that I have found. A********* The ratchet allows the tool to hold the crimp pin or socket securely while inserting the wire. Once the tool is fully closed and springs open the crimp pin is easily released unlike other brands and the wire and sheath crimps are showing the same closure as the machine produced crimps, with a similar insulation resistance end to end as machine made crips. The crimp tool is a good fit for my hands and the crimping pressure required to complete the crimp is comfortable for making 20 or 30 crimps at a time. Really glad I bought this tool, desertcarts delivery time was also fast.

## Questions & Answers

**Q: Will this work with the jst rcy terminals**
A: Yes，it works well with this jst rcy terminals.

**Q: hi would this work with mcon 1.2 pin terminals**
A: From what I can find out, no it would not because they are solder terminals.

**Q: Are the teeth interchangeable? I don't want to buy two whole units, but I'd take one a several sets of teeth.**
A: There are two diferent size openings in a single set of jaws to suit the different crimp sizes. Have used extensively with PH 2.0 connectors. After a bit of practice to get use to handling such small parts, worked very well giving consistent crimps strongly attached to the wires. This is very high quality, well made robust tool. Have no idea if different jaw sizes are available.

**Q: Will this tool crimp molex 0.093 connectors**
A: I have used it without any issues on such molex connectors. So for me the answer is yes. Specifically I used it for the following that I bought for a project.
2 Way Molex Connector Kit .093" 2 Pin Plug Socket & Terminals. I use the IWISS SN-28B version of the crimper

### ⭐⭐⭐⭐⭐ IWISS strike again with a great tool at a good price
*by M***P on 4 February 2023*

I needed a reliable crimper for small non-insulated connections and this IWISS tool is great and delivered by Amazon the next day through the letterbox. Previously I'd bought a cheaper generic SN-28B tool but even when using the correct connections the crimps I was making were failing and not formed correctly so I was wasting a lot of connectors. Buy cheap buy twice I guess. I've had IWISS tools in the past and initially missed this one when buying the SN-28B but gave it a go as the previous tool wasn't very good. Immediately the same set of non-insulated connectors I've been using are formed better on both the bit holding the cable insulation and the smaller part crimping the wire and most importantly aren't failing in the pull test or giving me random continuity problems. There's a bit too much wire in the cable in the pictures and I've also shown the size next to a pen - these are little so just a mm too long makes quite a difference! You also get some good instructions with these whereas a lot of crimpers you'll be left to your own devices to work it out (although they all have their own pitfalls, it just takes time to get used to each set). For me definitely worth paying that little extra over the generic crimpers if you value your time - these aren't as expensive as proper Molex crimps but still seem to do a more than good enough job. Thanks IWISS!
