What to look for in a crimping tool under £50
When shopping for a crimping tool under £50, the key factors are the type of crimp mechanism, the wire size range it supports, and the build quality. Ratchet-style crimpers provide consistent pressure and are preferred for electrical work, while plier-style crimpers are simpler and cheaper. Ensure the tool matches the terminal types you need, such as insulated or non-insulated connectors.
Material quality matters. Look for forged steel or hardened carbon steel jaws that resist wear. Ergonomic handles reduce fatigue during repetitive use. Owner reviews consistently highlight that a good crimping tool should produce a gas-tight connection that does not pull apart easily.
Mistakes to avoid when buying a crimping tool
A common mistake is buying a tool that only works with one type of connector. Many budget crimpers only handle insulated terminals, leaving you unable to crimp non-insulated or automotive spade connectors. Another error is ignoring the wire gauge range. A tool that only covers 1.5-2.5 mm² will not work for 6 mm² cables used in appliances.
Avoid tools with plastic pivot points. Owner reviews frequently report these breaking after a few uses. Also, do not assume all ratchet crimpers are equal. Some cheap ratchets slip or fail to release, causing poor connections. Always check the brand reputation and warranty before purchase.
Knipex 97 52 36
Best OverallPros
- Precision ratchet mechanism for consistent crimps
- Durable forged steel construction
- Ergonomic non-slip handles
Cons
- Higher price within the budget range
- Only suitable for insulated terminals
The Knipex 97 52 36 is widely regarded as the benchmark for hand crimping tools. Its ratchet mechanism ensures a full crimp cycle is completed before the tool releases, preventing partial crimps. Owner reviews on retailer sites praise its smooth operation and the solid feel of the joints. The forged steel jaws resist deformation even after hundreds of uses.
This tool covers wire sizes from 0.5 to 6 mm², making it suitable for most domestic electrical tasks. The ergonomic handles reduce hand strain during extended use. While it is at the higher end of the £50 budget, the build quality and reliability justify the cost for regular users.
Stanley FatMax FMHT0-61878
Best BudgetPros
- Multi-function: crimps, cuts, and strips
- Comfortable bi-material handles
- Good value for money
Cons
- Not a true ratchet mechanism
- Jaw alignment can drift over time
The Stanley FatMax FMHT0-61878 is a versatile tool that combines crimping, wire cutting, and stripping in one unit. It is ideal for DIYers who need a single tool for basic electrical jobs. Owner reviews highlight its comfortable grip and the convenience of having multiple functions. The carbon steel jaws provide adequate durability for occasional use.
Unlike the Knipex, this is a plier-style crimper without a ratchet. This means you must apply consistent pressure manually. For light-duty tasks like crimping spade connectors or butt splices, it performs well. However, for high-volume work, a dedicated ratchet tool is preferable. The price point makes it an excellent entry-level choice.
Bahco 1700
Best ErgonomicsPros
- Ergonomic handle design reduces fatigue
- Smooth ratchet operation
- Swedish brand known for durability
Cons
- Limited to insulated terminals only
- Not as widely available as Knipex
The Bahco 1700 is designed with user comfort in mind. Its handles are shaped to fit the hand naturally, and the ratchet mechanism requires less force to operate compared to many competitors. Owner reviews often mention that it feels lighter and more balanced than other ratchet crimpers. The hardened steel jaws maintain their sharpness and alignment over time.
This tool is best for electricians who spend long hours on repetitive crimping tasks. The wire range covers standard domestic and automotive sizes. While it is slightly less known than Knipex, Bahco has a strong reputation in the tool industry for producing high-quality hand tools. It is a reliable choice for professionals on a budget.
Draper 16432
Best for Network CablesPros
- Specifically designed for network connectors
- Includes built-in cutter and stripper
- Compact and lightweight
Cons
- Not suitable for electrical terminals
- Plastic handles may not be as durable
The Draper 16432 is a dedicated crimping tool for RJ45 and RJ11 connectors, making it perfect for networking tasks like making Ethernet cables. It features a built-in wire cutter and cable stripper, which adds convenience. Owner reviews on electronics retailer sites praise its ability to produce consistent crimps on 8P8C connectors without damaging the plastic housing.
This tool is not for electrical work. It is designed solely for modular connectors used in data and telephone cables. The steel jaws are precisely machined to fit the connector profile. For anyone setting up a home network or doing low-voltage cabling, the Draper 16432 is a reliable and affordable option under £50.
Sealey AK394
Best Multi-PurposePros
- Handles insulated and non-insulated terminals
- Integrated wire cutter
- Good for automotive work
Cons
- No ratchet mechanism
- Not as precise as dedicated ratchet tools
The Sealey AK394 is a versatile plier-style crimper that works with both insulated and non-insulated terminals. This makes it a good choice for automotive wiring, where you often need to crimp uninsulated spade or ring connectors. Owner reviews from automotive forums highlight its sturdy construction and the usefulness of the built-in wire cutter. The carbon steel jaws provide adequate strength for occasional use.
This tool lacks a ratchet, so you must rely on your own grip strength to achieve a good crimp. It is best for light to medium duty tasks. The price is very affordable, making it a good addition to a car toolkit. For heavy electrical work, a ratchet tool like the Knipex is recommended, but the Sealey AK394 offers flexibility at a low cost.
