If you are wiring PLC panels, control cabinets, relays, contactors, terminal blocks, VFD control terminals, sensors, or 24V DC circuits, a ferrule crimping kit is one of the most useful tools to have.
A ferrule is a small metal sleeve that goes over the end of a stranded wire. After crimping, it keeps the wire strands together and makes the connection cleaner and more reliable.
Without ferrules, stranded wires can spread out, break, or sit badly inside terminal blocks.
Ferrules are useful for:
PLC inputs and outputs
Terminal blocks
Control cabinet wiring
Relay wiring
Contactor control wiring
VFD control terminals
Sensor wiring
24V DC circuits
Small automation panels
Electrical training boards
Below are 5 Amazon ferrule crimping kits I would consider, starting from cheaper beginner kits and moving toward more professional options.
Amazon prices change often, so always check the current price before buying.
Important Note Before Buying
Ferrule crimpers are not all the same.
Some make square crimps.
Some make hex crimps.
Some are better for small control wires.
Some support larger ferrules.
Some kits include ferrules, wire strippers, and storage boxes.
Also, always check the terminal manufacturer’s recommendation. Some terminal blocks work very well with ferrules, but the ferrule size and crimp quality still matter.
A bad crimp is not better than no crimp.
1. SOMELINE Ferrule Crimping Tool Kit — Best Cheap Starter Kit
Best for: beginners, PLC learners, simple control wiring
Affiliate link: [SOMELINE Ferrule Hexagonal Crimping Tool ]
The SOMELINE Ferrule Crimping Tool Kit is a good low-cost option if you are just starting with ferrules.
The Amazon listing describes it as a self-adjusting ferrule crimping plier kit for AWG 24–8 wire ferrules, with 9 sizes of insulated wire ferrules included.
Why I recommend it
I recommend this one for beginners because it gives you the tool and ferrules in one box.
That is useful when you are learning because you do not need to buy everything separately. You can practice crimping, test how ferrules fit into terminal blocks, and start using them on small control wiring projects.
It is good for:
Beginner PLC panels
Relay wiring practice
24V DC control circuits
Terminal block wiring
Small automation projects
Main weakness
It is a budget kit.
For professional daily panel building, I would eventually upgrade to a better crimper. But as a first ferrule kit, it is a practical starting point.
2. Preciva Ferrule Crimping Tool Kit — Best Budget Kit With Many Ferrules
Best for: beginners who want a bigger ferrule assortment
Affiliate link: [Preciva Ferrule Crimping Tool Kit]
The Preciva Ferrule Crimping Tool Kit is another good budget-friendly option.
One Amazon listing describes the kit as including a crimping tool and 1200 insulated wiring terminals. Another Preciva listing includes crimping pliers for AWG 28–5, a wire stripper, 1110 single ferrules, 265 twin ferrules, and a storage box.
Why I recommend it
I like this one because it gives you a lot of ferrules for the money.
For beginners, that is useful because you will probably make some bad crimps while learning. Having extra ferrules lets you practice without worrying too much.
It is good for:
Electrical panel practice
PLC wiring projects
Control cabinet training
Terminal block wiring
Learning single and twin ferrules
The version with twin ferrules can be especially useful if you need to connect two wires into one terminal, assuming the terminal is rated for that use.
Main weakness
There are different Preciva kits, so check carefully before buying.
Make sure the wire size range matches the wires you actually use. For PLC panels, small stranded wires are common, so do not buy a kit that misses your most-used sizes.
3. IWISS / iCrimp Ferrule Crimping Tool Kit — Best Reliable Budget-to-Mid Option
Best for: automation beginners, electricians, control panel wiring
Affiliate link: [iCrimp Ferrule Crimping Tool Kit]
The IWISS / iCrimp Ferrule Crimping Tool Kit is a popular option for people who want a better crimping tool without going straight to expensive professional tools.
One Amazon listing describes the iCrimp / IWISS HSC8 6-4A as a self-adjusting ferrule crimper for AWG 23–10, or 0.25 mm² to 6.0 mm², with a square-style crimp. It also mentions twin ferrule capability from 2×22 to 2×14 AWG.
Another Amazon listing says the iCrimp kit includes a ferrule crimping plier and 770 wire ferrules for AWG 22–10.
Why I recommend it
I recommend this one because the wire range is useful for many control panel jobs.
For PLC and automation wiring, you often work with smaller stranded wires. A ferrule crimper that handles those sizes well is very useful.
It is good for:
PLC panels
Automation training boards
Control cabinet wiring
VFD control wiring
Relay and terminal block work
General electrical maintenance
Main weakness
Some kits include only the crimper, while others include ferrules.
Check the Amazon listing carefully before buying so you know exactly what is included.
4. Haisstronica Ferrule Crimping Tool Kit — Best Bigger Kit With Stripper and Ferrules
Best for: beginners and technicians who want a complete organized kit
Affiliate link: [haisstronica Ferrule Crimping Tool Kit]
The Haisstronica Ferrule Crimping Tool Kit is a good choice if you want a more complete ferrule kit.
One Amazon listing says the kit includes a wire crimping tool, wire stripping pliers, and 2500 wire ferrule terminals, with 12 terminal sizes from AWG 22–7.
Another Haisstronica listing describes a ferrule crimping tool for AWG 28–10 with 1200 ferrules included.
Why I recommend it
I like this one because it can give you a full setup in one box.
You get the crimper, ferrules, and in some versions, a wire stripper too. That makes it useful for people building their first proper panel wiring tool set.
It is good for:
PLC cabinet wiring
Terminal block wiring
Maintenance tool bags
Electrical training
Automation beginners
Small control cabinet projects
Main weakness
There are multiple Haisstronica ferrule kits, and they are not all the same.
Before buying, check:
Ferrule count
Wire size range
Whether a stripper is included
Storage box quality
Crimp shape
Single vs twin ferrule sizes
Do not choose only by the number of ferrules.

My Final Recommendation
If you want the cheapest starter option, I would choose the SOMELINE Ferrule Crimping Tool Kit.
If you want a budget kit with many ferrules, I would look at the Preciva Ferrule Crimping Tool Kit.
If you want a popular budget-to-mid crimper for automation wiring, I would choose the IWISS / iCrimp Ferrule Crimping Tool Kit.
If you want a larger complete kit with stripper and many ferrules, I would consider the Haisstronica Ferrule Crimping Tool Kit.
If you want the best professional all-round choice, I would choose the Klein Tools 34060 or Klein Tools 34061.
My personal pick for beginners would be the IWISS / iCrimp kit or Haisstronica kit, depending on price.
For professional panel wiring, I would choose the Klein Tools ferrule crimping set.
What to Look for When Buying a Ferrule Crimping Kit
When choosing a ferrule crimping kit, check:
Wire size range
AWG and mm² compatibility
Square or hex crimp profile
Ratcheting mechanism
Self-adjusting jaws
Ferrule count
Single ferrules included
Twin ferrules included
Wire stripper included
Storage box quality
Crimp consistency
Comfortable handle
Trusted brand
For PLC panels and control cabinets, I would pay close attention to the smaller wire sizes. Many control wires are small stranded conductors, so the crimper must handle them cleanly.
Why Ferrule Crimping Kits Are Worth Buying
Ferrules make panel wiring cleaner and more professional.
They help prevent loose strands, improve terminal insertion, and make troubleshooting easier later.
A panel wired with ferrules usually looks cleaner, feels more organized, and is easier to maintain.
If you are learning PLC wiring, electrical panels, relays, contactors, VFD control terminals, or automation maintenance, a ferrule crimping kit is one of the first tool upgrades I would recommend.
Cheap kits can get you started.
Good crimpers make the work cleaner and more reliable.
