I find the ratchet type always seem to do a better job because they consistently apply the correct crimping pressure until release. I've seen some cheapish ratchet crimps with interchangeable dies for around $25 which look like they cover everything but I always worry about the quality of something that cheap. An example of some of those are HERE. If anyone has any particular recommendations or endorsements of a crimping tool they use that fits my requirements, then can you please let me know which one(s) you use. • Posts: 909 Threads: 59 Likes Received: 543 in 318 posts Likes Given: 730 Joined: Nov 2018 Reputation: 26 01-Mar-2019, 12:50 AM (This post was last modified: 01-Mar-2019, 12:51 AM by Scott_M.) Hi Snow I have 2 IWiss crimpers one is SN-28B which is for larger connectors it is the ratchet type and works very well. I needed a set for smaller connectors and was happy with the IWiss quality so looked there first, I ended up with a basic style ( no ratchet ) but for the little connectors it is fine. It's number is IWS-2820M and it was only about $15 if I remember correctly. I got it on Amazon. The smallest set works for JST-SH. These are single crimp so you have to do the wire and insulation separately, I think it gives more control I Found it Scott Posts: 12,098 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 I have two IWISS crimpers. Both works great. It is nicer to actually have two crimpers rather than changing the die all the time. https://www.amazon.com/dp/B00OMM4YUY/ref...ECbFF1YVK8 https://www.amazon.com/dp/B078WPT5M1/ref...ECb5X1T4V1 Posts: 21,397 Threads: 593 Likes Received: 9,029 in 6,683 posts Likes Given: 1,428 Joined: Jun 2018 Reputation: 795 Thanks guys. Typically the IWISS gear seems to be sold at rip-off prices in the UK. Probably because it's imported. I've found what look like clones of the same but I need to be sure that it's not some cheap knock-off tat that will fall apart after 5 minutes of use, so I'll check out some reviews. • Posts: 12,098 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 I can tell you that the ones I got were fulfilled by Amazon and they are quality. • Posts: 5 Threads: 0 Likes Received: 3 in 3 posts Likes Given: 0 Joined: Jan 2019 Reputation: 0 Here is a good article I just read today on crimping http://tech.mattmillman.com/info/crimpconnectors/ and all the different types of connectors and their "official" crimpers.

As an example, this is the same branded IWISS SN-28B on the Amazon UK website as are selling for $23 on the US Amazon website... https://www.amazon.co.uk/dp/B017JU20Z6 £44 delivered, which converted to US currency works out at almost $60 USD Alternatively I can get branded IWISS ones from China for $23 delivered but I would have to wait ~4 weeks for them... https://www.aliexpress.com/item/SN-28B-c...66039.html Some cheaper "clones" of the same are here... https://www.amazon.co.uk/s/ref=nb_sb_nos...rds=SN-28B To be fair, some of them do seem to get OK reviews. • Posts: 12,098 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 I see what you mean. The Engineer crimpers look attractive considering the alternative. • Posts: 21,397 Threads: 593 Likes Received: 9,029 in 6,683 posts Likes Given: 1,428 Joined: Jun 2018 Reputation: 795 Just a quick update to this. I still don't have a pair of crimps, but Andreas just posted a very useful comparison between the IWISS IWS-2820M and Engineer PA-09 crimps on his YouTube channel which might be useful for others who are also considering getting a pair. Spoiler alert: The IWISS come out as the winner. I can get those in the UK from Amazon for 15 GBP (~$18) delivered. This compares to 40 GBP (~$48) for the PA-09. So getting a pair of the IWISS over the PA-09 is a no-brainer. • Posts: 909 Threads: 59 Likes Received: 543 in 318 posts Likes Given: 730 Joined: Nov 2018 Reputation: 26 I tried pushing the 2820M on you back in post 2.

I guess I should have just taken your advice in the first place I ordered a pair this morning shortly after posting Andreas' video. They should be with me by Thursday. Now I just need to get a selection of JST connectors to use with them Posts: 12,098 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 I think I have been recommending the IWISS for a while to you too. • Posts: 21,397 Threads: 593 Likes Received: 9,029 in 6,683 posts Likes Given: 1,428 Joined: Jun 2018 Reputation: 795 (11-Aug-2019, 04:35 PM)voodoo614 Wrote: I think I have been recommending the IWISS for a while to you too. It's only when you see actual visual comparative proof that you then believe a $18 tool really is just as good or better than a $48 tool • Posts: 12,098 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 I like the IWS-3220M for micro connector. Because it ratchet, you can hold the connector and thread the wire easier. • Posts: 21,397 Threads: 593 Likes Received: 9,029 in 6,683 posts Likes Given: 1,428 Joined: Jun 2018 Reputation: 795 (11-Aug-2019, 04:51 PM)voodoo614 Wrote: I like the IWS-3220M for micro connector.
