Ratchet Crimping Plier Preciva insulated wire terminal crimp tool for AWG 20–10 up to 6mm²
Product description
The essentials
If you do regular electrical connector work, a ratchet crimping tool can make the difference between a tidy, reliable termination and one that feels “a bit off”. This Ratchet Crimping Plier from Preciva is an insulated wire terminal crimp tool designed for crimping insulated wire terminals using a ratcheting mechanism with a lever action.
On paper, it’s aimed at people who want repeatable crimps without grinding their hands to dust. The grip design is positioned to reduce slipping and hand fatigue during longer jobs, while the jaw design and forced locking are there to help the crimp look smooth and sit firmly.
That said, it’s not a magical solution for every situation. If you’re not crimping insulated terminals (or your wire/terminal combination sits outside the stated range), you may find it doesn’t perform as hoped. It’s one of those tools where getting the match right matters more than the brand name.

What you’ll notice day to day
This tool uses a ratcheting + lever double design, which is specifically called out as labour-saving. The practical effect of that, in everyday terms, is you get more leverage when forming the crimp and a more controlled pull as the tool locks in.
The handle design is also described as “2023 newly updated”, with a focus on preventing sliding and reducing fatigue. If you’ve used cheaper pliers that feel slippery or require an awkward grip, this is the sort of improvement you’ll appreciate when you’re doing multiple terminations back to back.
Also worth noting: a forced locking / self-locking device is mentioned, so it’s built around the idea of consistent compression. That’s useful if you’re working through connectors for workshop jobs, auto repairs, machinery maintenance, or general circuit work where consistency matters.



Where it shines (and where it can fall short)
Where it shines is straightforward: crimping insulated wire terminals with a more controlled, ratcheted action. For many buyers, that’s the main requirement—something that closes properly, forms a solid crimp, and doesn’t feel like it’s fighting your grip.
However, you should temper expectations if your work is highly specialised. The listing positions this as an all-rounder for maintenance and workshop use rather than an instrument-grade crimper for exotic cable/terminal combinations. If your terminals or wires don’t align with the tool’s stated range, performance and crimp quality can quickly become hit and miss.
Key specifications (range to check before buying)

- Type: Ratchet crimping plier for insulated wire terminals
- Wire size range: AWG 20–10 (0.5–1.5mm²), 1.5–2.5mm², and 4–6mm²
Is it a good fit for you?
It’s a good fit if you regularly handle electrical circuit maintenance, workshop connector work, auto repair wiring, or machinery/automobile electrical connections and you want a ratcheting insulated crimp tool that’s built around repeatability.
It makes sense if you value labour-saving operation and prefer a tool that helps reduce hand fatigue during longer sessions.



It’s not the best choice if your projects use wiring or insulated terminals outside the stated size range, or if you’re only doing occasional, one-off crimps and don’t want to commit to a proper crimping tool.
And a small but important point: even with a ratchet tool, the quality of the result depends on correct matching—wire gauge, terminal type, and proper placement before you squeeze. That’s usually where the “it didn’t crimp properly” complaints come from.
Practical tips for getting reliable crimps
Before you fully commit to a run of connectors, do a quick check: line the insulated terminal and conductor up correctly in the jaw so the crimp sits where it should. Then squeeze steadily until the ratchet action completes the cycle. If the tool has locked/forced the crimp as intended, you should feel that the process is more consistent than with non-ratcheting pliers.

A micro-example: imagine you’re re-terminating a length of automotive wiring in a workshop. You strip the cable, insert it into the insulated terminal, align it in the correct position on the tool, and squeeze through the ratchet until it releases. That repeatable motion is exactly what ratchet crimping is meant to deliver.
Should you buy it?
Worth considering if you need a ratcheting, insulated wire terminal crimp tool for everyday workshop and maintenance tasks, and your wire size falls within the stated AWG and mm² range.
You may want to skip it if you’re unsure about wire/terminal compatibility or you work outside the stated sizes. In those cases, the tool’s value drops because crimping results depend heavily on the match between the terminal and the conductor.



Mini FAQ
How many tools are included in the box?
The listing states that the pack includes 1 ratcheting wire crimper tool and 1 user manual.
Is it suitable for industrial or auto work?
Yes, the product description specifically mentions use cases such as electrical circuit maintenance, workshops, auto repair electricians, and machinery or automobile work.
What range of wire sizes does it cover?
It’s listed for AWG 20–10 (0.5–1.5mm²), 1.5–2.5mm², and 4–6mm². It’s sensible to double-check your wire size falls within that range before buying.
Does the ratchet mechanism matter?
If you’re chasing consistent crimps, the ratcheting and self-locking/forced locking features are the point. They’re designed to help achieve a smooth, firm crimp and reduce the guesswork.
