If you’re anything like me, you’ve probably tried a number of crimping tools—some good, some not-so-good, and some that left you crimping twice just to get a decent hold. So when I got my hands on the Haisstroncia 6pcs Crimping Tool Set, I was curious to see if it could really replace a toolbox full of crimpers. But after testing it for a few weeks, I can confidently say: this crimping tool set is a keeper.
One Tool, Six Functions — Replaces 6 Different Crimpers!
The standout feature of this Haisstroncia crimping tool set is its versatility. It comes with six interchangeable die sets, and each die is designed for a specific type of terminal. With just one crimp tool, you can cover almost every crimping scenario you’ll encounter.
6 Die Sets of Haisstroncia Crimper Tool
Here’s what each die does:
-
Die Set A – For heat shrink connectors and terminals. Ideal for automotive and marine applications where you need moisture protection.
-
Die Set B – For insulated terminals. My go-to for standard wiring jobs.
-
Die Set C – For non-insulated terminals. Offers excellent conductivity where insulation isn’t needed.
-
Die Set D – For open barrel terminals, often found in OEM automotive wiring.
-
Die Set E – For ferrule terminals. A must-have if you’re working on control panels or stranded wire.
-
Die Set F – For Solar MC4 connectors. I didn’t expect to use this one, but it came in handy for my solar projects. It makes a solid crimp on an MC4 connector barrel.
Having all six of these in one kit saves space, time, and money. No need to juggle a drawer full of single-purpose crimping tools.
Solid Construction and Professional Feel
The tool itself feels sturdy and well-built. The forged jaws are crafted with precision technology, which gives you even, consistent crimps every time. Unlike those cheap crimpers that press on a tiny spot and force you to crimp twice, this one gets it right in one go—one and done.
The ratcheting mechanism is smooth and precise. You can pre-clamp the connector in the jaws, insert the wire afterward, and then finish the crimp. This is especially helpful when working in tight or awkward spaces.
And yes, it automatically springs open after each crimp. That may seem like a small feature, but it makes a big difference when you’re working quickly.
Comfortable, Ergonomic Grip
The handle is a blend of molded plastic and rubber, making it both comfortable and non-slip. Even during long sessions, the grip feels good in the hand. I’ve crimped 18, 16, 14, and 10-gauge wires with it. Some thinner wires need a bit more force, but I can still handle it with one hand.
Easy Die Swapping
Switching dies is refreshingly simple. Just use a Phillips screwdriver to remove two screws, swap the die, and screw them back in. The set even includes two extra screws, just in case you lose any (and let’s be honest, we all do eventually).
Even better, the storage case is labeled, with each die having its own slot marked A through F. I got the standard kit but the premium one includes a laminated reference card that shows the type of connectors and wire sizes each die supports. Super useful when you are just getting started with the kit.
Excellent Performance
So far, I’ve used this crimping tool for automotive wiring, some basic electrical jobs, and even a solar setup. I did have to adjust it for smaller gauge wires on my tiller project, but once I did, it worked like a charm.
My only real gripe? The tool is a bit bulky, which made it tricky to fit into some cramped spaces—like underneath the chassis wiring in my truck. Also, note that the set doesn’t include connectors, just the tool and dies.
