Is The Iwiss 3220M Ratcheting Crimp Tool Any Good? | Voltlog

High quality PCB Services https://pcbway.com Join me in this video where we take a closer look at the IWISS IWS-3220M ratchet crimp tool which can do very small crimps like: JST-SH, Tyco D-1000, Molex CLIK-Mate and others. Is this tool any good? I’ll test it by trying to crimp some JST-PH connectors. And I will be comparing with the previous IWS-2820 non ratchet crimping tool that I reviewed in Voltlog 425.

#IWISS #Crimp #IWS-3220M


I have a couple of popular videos on my channel where I take a look at some affordable crimping tools, the most recent one Voltlog 425 where I looked at the IWISS mini 2820M, this is a dual action crimping tool, meaning that you will have to crimp first the insulation then the electrical connection, it’s cheap, it works but it does require a bit of extra work, a bit of extra attention for correct positioning of the crimp on the die, careful applying of force and a bit of practice on the user side to get a usable crimp.

My viewers recommended in the comments that I should also take a look at the ratcheting crimp tool from IWISS which is isn’t that much more expensive but should be easier to use, less fiddling, will crimp both parts of the crimp at the same time, won’t let you apply too much pressure which would crush the crimp so overall it should provide a better user experience and better crimps, at least in theory.

The model number for this is IWIS-3220M, comes in similar packaging, once again, there is some great information on the packaging itself, the list of supported crimp types, list of wire size vs the correct slot on the die as well as a bunch of tips & tricks on how to get a good crimp. This tool is rated for AWG32 up to AWG20 wire size in sq mm that would be 0.03 up to 0.52 sq mm, for my particular use case this is the range of crimps and wire sizes that I commonly use at my electronics workbench.

By the way should you decide to get one of these after watching my review there will be some links in the description of the video with places where you can order this tool so check them out.

Construction wise, like I mentioned earlier, this is ratchet type crimp, quite a weak spring action on the mechanism, I would have preferred a bit more force in the spring they use but that shouldn’t affect the quality of the crimps. There are rubber handles which feature this lock here to prevent them from sliding on the metal handle, that’s nice attention to detail. You would have to watchout to not get your fingers caught in the ratchet mechanism which sits here on the handles.
