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 Haisstronica 6pcs Crimping Pliers Set, I was curious to see if it could really replace a toolbox worth of crimpers. But after testing it for a few weeks, I can confidently say: this crimping set is a keeper.
One Tool, Six Functions — Replaces 6 Different Crimpers!
The standout feature of this Haisstronica crimping 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 tool, you can cover almost every crimping scenario you’ll encounter.
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 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 re-crimp, 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 on the Haisstronica multicrimp pliers is fairly simple. Just use a Phillips screwdriver to remove the screws, swap the dies, and attach the screws back. There’s even two extra screws in the kit, just in case you lose one.
And if removing the screws is too much work, Haisstronica offers an alternative model that does not require a tool to remove dies. It has an inbuilt locking mechanism that locks the dies in place and you just need to squeeze in the locking levers to release the dies when changing them out. This kit comes in a nice branded carry bag with velcro straps inside to hold the tool in place. It also has mesh pockets inside to store the die sets. Check it out in this video I created.
For the plastic storage case, it has labelled slots for each die. It makes it easy to organize the die sets and tell which one is missing. The premium kit even includes a laminated reference card that illustrates the type of connector and wire guage for each die set. This is super useful, especially for a beginner or DIYer.
Excellent Performance
So far, I’ve used this 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.
