iCrimp IWS-3220M Micro Connector Pin Crimping Tool 0.03-0.52mm² 32-20AWG Ratcheting Crimper for D-Sub,Open Barrel suits Molex,JST,JAE

This is a nicely built crimper. I've used crimpers before but not this particular style. Amazon says, "comes with instructions", but not with my copy so I had to do a little trial and error to get good crimps without crushing the pin insert end of the connector. The numbers on my copy of the crimper differ slightly from the Amazon illustration with the largest being 2.0mm instead of the 1.9mm shown. No biggie. The tool has a good ratchet mechanism which is used to hold the connector in place while the wire end is inserted and then the crimp is finished. Makes great crimps. It's coated with some kind of lubricant which stains so be careful no to lay it on your prize tablecloth when taking it out of the protective plastic bag. Wiping it down doesn't help because there's more lubricant in the bag so it's coated again the next time you remove it. You probably don't want it lubricant free, because this lubricant probably contains a corrosion inhibitor to preserve the tool.Very good tool for the price and works well, but when crimping, be sure to check the insertion distance so the actual connector doesn't get crushed in the process.

I love these things! Such a life saver! Ive used them countless times at this point!Just the right size for anyone into 3d printers! They're accurate, crimp well, and work great once you get the hang of them.I suggest crimping some trash wire just to get a feel for them before you send it and use them on a project.

These crimpers are great. Pretty easy to use and crimps the small connectors easily. I was trying with a crimper with a similar die (which was a little bit bulky). Love this. I wish I bought this earlier. I'm going to re-crimp all of my wires again to get better crimps.

These make great crimps for JST "zh" connectors. It crimps the pins without overly squashing them, so that they will fit into the connector immediately after crimping.I had previously tried one of the "SN-01BM" crimpers for these, but the anvils were a bit too large and squashed the pin too much, making it too wide to fit into the connector, without taking some small pliers and squeezing the sizes to reduce the width again.The crimps I get with this crimper also look significantly better than I had gotten with the SN-01BM, which is probably a function of having a more appropriately sized anvil for the pin.My only complaint about this crimper is that it doesn't feel nearly as good as the SN-01BM. The SN-01BM feels much more sturdy and well built, while the IWS-3220M feels flimsy and cheap in comparison. I also prefer the slight angle of the jaws on the SN-01MB. If only I could get this anvil set on a SN-01BM. Ah well :)

Same quality as the Snap On branded one for 1/4 the price! Big W, boys

This is my first crimping tool. I was so excited when it arrived, I felt like a kid with a toy. I have never crimped before but this tool is fantastic. It's light yet sturdy, and it grips comfortably. Feels just right in my hands. With a few tries I was crimping like a pro.

Great set of crimpers.. As another reviewer stated. Make sure your putting the pins in the right direction.. and there not to far or short in the jaw position.. Then slightly crimp to hold the pin. Then push the wire in. They work great and for an E-Bike you need these!! Makes for a great time savor and short work..Used for larger pins as well, you just have to be carful not to crimp to tightly and flip the spring loaded release up first.
