The right crimper gives you a clean, repeatable connection instead of a loose ferrule, a crushed terminal, or a joint that fails the first time the cable is tugged. For electrical work, the difference is usually in the jaw profile, crimp range, and how consistently the tool closes under load.
This guide compares the most relevant crimpers for UK electrical jobs, from fine ferrule work at 0.25-6mm² to heavier 10-120mm² hydraulic crimping. It is for DIYers, electricians, and installers who want the right tool for the connector type they actually use, not a vague all-purpose plier that does a poor job on everything.

C.K Ratchet Crimping Pliers for Bootlace Ferrules 0.25-6mm²
“It covers the most common ferrule sizes at 0.25-6mm², which is exactly the range many control and panel jobs need.”
This is the most focused option here if your work is mainly bootlace ferrules. The stated 0.25-6mm² range covers everything from very small conductors up to fairly chunky stranded cable ends, so it fits a wide spread of everyday electrical terminations without moving into specialist territory.
The drawback is that we do not get much else to judge from the supplied data, so there is no published jaw detail, weight, or release mechanism to compare. That makes it harder to assess comfort or build quality on paper, and it is not the tool to buy if you need insulated terminals or heavier cable lugs rather than ferrules.
- Covers bootlace ferrules from 0.25-6mm²
- Ratchet action should help deliver consistent closures
- Well matched to panel and control wiring
- No extra specs are provided for jaw design or build
- Limited to ferrules rather than broader connector types
Best for: Electricians and DIYers who mainly terminate bootlace ferrules in the 0.25-6mm² range
💬 Verdict: Buy this if ferrules are your main job and you want a proper ratchet crimper without unnecessary extras.
£75-£100
Bahco CR W 01 Ratcheting Crimping Pliers for Insulated
“Its 0.5 mm² to 6 mm² cable section range and insulated-connector focus make it a neat fit for general electrical terminations.”
This is a sensible mid-range choice for insulated connectors, with a stated cable section range of 0.5 mm² to 6 mm². That span is useful for a lot of domestic and light commercial work, and the high leverage design should make repeated crimps less tiring than a basic plier-style tool.
The weakness is that it is still limited to smaller cable sizes, so it will not suit heavier lugs or larger distribution work. The supplied data is also thin beyond the size range, so while it looks well aimed at everyday insulated terminals, there is not much detail to separate it sharply from other ratcheting pliers on paper.
- Covers 0.5 mm² to 6 mm² cable sizes
- High leverage design helps with repeated crimping
- Made for insulated cable connectors
- Not suitable for larger heavy-duty cable work
- Little published detail beyond the basic size range
Best for: Anyone doing regular insulated terminal work on small to medium cable sizes
💬 Verdict: A strong all-rounder for insulated terminals if your cables stay within 0.5 mm² to 6 mm².
£75-£100
Draper 56383 Expert Ratchet Crimping Tool and Terminal Kit
“Its carbon steel jaws and preset tension system are aimed at repeatable crimps, which is exactly what matters on terminal work.”
This looks like a practical kit option for someone who wants a ratchet crimper with a bit more substance than a bare tool. The carbon steel construction, hardened and tempered jaws, and continuous crimping at preset tension all point towards more controlled, repeatable results on terminal work.
The issue is that the listing gives almost no crimp-size data at all, so you cannot tell from the supplied information which cable sizes it best suits. The 590 size figure is not very helpful for job matching on its own, and the kit format may be more than you need if you already own the right terminals separately.
- Carbon steel jaws with hardened and tempered treatment
- Preset tension supports consistent crimping
- Includes a terminal kit rather than tool only
- No clear cable or ferrule range is provided
- Kit format may be unnecessary if you only want the tool
Best for: Buyers who want a ratchet crimper plus terminals and value consistency over minimal packaging
💬 Verdict: Worth a look if you want a sturdier-feeling kit, but the missing size data makes it harder to pin down.
£75-£100
KNIPEX Preciforce Crimping Pliers 220 mm, 97 52 36
“At 220 mm long, it is a compact precision crimper that should suit controlled electrical work where hand feel matters.”
This is the most clearly premium hand tool in the list by reputation, and the 220 mm length suggests a compact, controlled crimping plier rather than a bulky heavy-duty model. That makes it a sensible choice for precise electrical work where access and repeatability matter more than brute force.
The main downside is that the supplied data gives no stated crimp range or connector type, so there is not enough here to say exactly which electrical jobs it is best at. For a buyer who wants clear specification-based matching, that lack of published detail is a real drawback, even if the tool itself is likely well made.
- Compact 220 mm tool for controlled work
- Likely best suited to precision crimping tasks
- A good fit where access is tighter
- No stated crimp range in the supplied data
- Connector type is not specified
Best for: Experienced buyers who want a compact precision crimper and are happy to choose on tool quality rather than published range
💬 Verdict: Choose this if you value precision and compact size, but do not expect the listing to spell out its working range.
£30-£50
KATSU Tools 12 Ton Hydraulic Crimping Tool 10-120mm²
“Its 10-120mm² crimping range and 8 sets of dies make it the clear choice for heavy cable work.”
This is the obvious heavy-duty option. With a 10-120mm² crimping range and 8 sets of dies, it is built for large cable lugs, power wiring lines, and end sealing jobs rather than the smaller terminals most domestic electricians crimp every day.
The trade-off is size and purpose. A 12 ton hydraulic tool is overkill for fine terminal work, and the manual U-shape head with on-off control means it is more of a workshop or installation tool than a quick everyday plier. It is also the least convenient option for tight spaces and light-duty repairs.
- Covers a wide 10-120mm² crimping range
- Includes 8 sets of crimping dies
- Suitable for heavy power wiring and cable lugs
- Far too large for small ferrules and terminals
- Bulkier and slower than hand ratchet crimpers
Best for: Installers and electricians who need to crimp large power cables and butt connectors
💬 Verdict: The right pick for heavy cable work, but it is not the tool for everyday small-terminal crimping.
What to Look For — Buyer’s Guide
What to Look For
Start with the connector type. Bootlace ferrules need a ferrule-specific crimper, insulated terminals need a tool matched to insulated connectors, and large cable lugs need a hydraulic model with the right die range. The most useful numbers are the crimp range and cable section, such as 0.25-6mm², 0.5 mm² to 6 mm², or 10-120mm². If the listing does not state a range, you are buying on trust rather than spec.
Also pay attention to the action of the tool. Ratchet crimpers are better for repeatable results because they close in a controlled way, while hydraulic tools are for larger conductors and need more space. Build details matter too: carbon steel jaws, hardened and tempered jaws, or high leverage designs usually point to a more durable, easier-to-use tool.
How Much Should You Spend?
For small electrical work, a focused ratchet crimper is usually enough, especially if it clearly states a range like 0.25-6mm² or 0.5 mm² to 6 mm². If you want a better-finished tool with more consistent crimping, the higher end of the ratchet market is where the stronger materials and smoother action tend to appear. For large cable work, a hydraulic crimper is the specialist buy, because no small hand tool will properly handle 10-120mm² lugs.
As a rule, spend for the job you actually have. A cheap oversized crimper is wasted money if you only do ferrules, and a small ratchet tool is the wrong answer if you are working on heavy power cables.
What we would skip
We would skip generic multi-tools that claim to crimp, strip, and cut everything in one body. They usually do none of those jobs as well as a proper dedicated crimper, and with electrical work that is not a safe place to compromise.
Our Verdict
Our top pick is the C.K Ratchet Crimping Pliers for Bootlace Ferrules 0.25-6mm², because it targets the most common ferrule sizes cleanly and without unnecessary bulk. The runner-up is the Bahco CR W 01 Ratcheting Crimping Pliers for Insulated, which suits insulated terminals well across 0.5 mm² to 6 mm² and is a strong everyday choice for general electrical work.
Frequently Asked Questions
What size crimping tool do I need for bootlace ferrules?
Look for a ferrule crimper with a stated range that matches your cables, such as 0.25-6mm². If your work is mostly panel wiring, that range is usually the right place to start.
Can I use the same crimper for insulated terminals and ferrules?
Not reliably. Some tools are made for insulated connectors, while others are built specifically for bootlace ferrules. Matching the jaw design to the connector is the safer choice.
When do I need a hydraulic crimping tool?
When the cable gets large enough that a ratchet hand tool is no longer practical. In this guide, the hydraulic option is for 10-120mm² work and is aimed at heavy power wiring, not small domestic terminals.
