Review on 🔧 Glarks 486Pcs Wire Crimper Plier with Connector Set - SN-28B Ratchet Crimping Tool and Dupont Pins Kit: 2.54mm 1-7 Pin Housing Connectors, Male/Female Pin Headers - AWG28-18 by Evan Austin

I'm a total newbie to this style of crimping (I've made coax and RJ45 and regular auto-wiring connector types; oh, and DB25 and DB9 cable connectors back then). Thankfully, there are plenty of good tutorial videos out there ("dupont connector" and "sn-28b" are useful search terms). If you're new to this too, look at a few from different people and choose half a dozen connectors and a couple of terminal blocks to practice with before trying to do the actual work. As far as I can tell from YouTube and my own learning experience these pliers are excellent, but the process requires considerable skill to use them effectively and you just need to take the time to learn them. I mean an hour and I started working properly, albeit a little slowly, just working out on my own. But it started with the assumption that before I started studying in a systematic way, I had to study so as not to waste time on failure. I don't want to criticize this tool in any way; This tip applies to *any* crimping tool of this type. I'm usually better at learning from text, but this kind of physical manipulation helps me see how it's really happening. There's even an adaptation that I haven't quite figured out yet. The crimp dies are more complex than I expected, with two different sized sides, one for the portion of the pins that grips the insulation and the other for the portion of the pins that grips the conductor itself. Learn which side is which, and how to tell (by touch) when a pin is in the right place. Then learn to tell when the wire has penetrated deep enough. You need surprisingly little stripped wire - to be honest, 1mm is fine.
