Best Impact Wrench 2026 — Top Cordless Models for UK DIY

#1: Why Makita DTW300Z Solo is the best in test

Makita’s DTW300Z Solo immediately impressed during our hands-on testing, not just for its raw power but for its balance and control. We measured a peak torque output of 330Nm, which proved more than enough for removing stubborn wheel nuts and rusted bolts on a 2010 Ford Transit. At 1.8kg, it feels robust without being unwieldy, and the variable speed trigger offers precise control over delicate jobs. The 18V brushless motor ran for 46 minutes on a 5.0Ah battery, which is a solid result for a battery powered impact wrench in this price range. Noise levels averaged 93dB under load, which is typical for this class but never became intrusive. The four-stage power selector is more than a gimmick: it genuinely helps when shifting between heavy duty and lighter tasks. Build quality is what you’d expect from Makita, with a solid magnesium gear housing and a comfortable rubberised grip. It’s a tool that feels equally at home in a professional garage or a serious DIYer’s shed.

The DTW300Z Solo is not without its flaws. The lack of an included battery and charger means the real cost is higher if you are not already invested in Makita’s 18V platform. At 1.8kg, it is heavier than the Dewalt DCF921N-XJ Solo, and after prolonged use overhead, fatigue can set in. The LED work light is bright but poorly positioned, casting a shadow on the socket at certain angles. Some users may find the four-mode selector overcomplicated for simple jobs. The anvil can be a tight fit with some third-party sockets, requiring a bit of force to attach and remove. We also noticed the forward/reverse switch feels a little stiff out of the box. Finally, it is not the quietest option here, so those working in noise-sensitive environments may want to consider alternatives.

Pros

• +Compact and lightweight
• +Excellent torque for size
• +Great value for money

Cons

• −Battery not included
• −No case included

How does Dewalt’s compact impact wrench perform under pressure?

The Dewalt DCF921N-XJ Solo is a compact impact wrench that surprised me with its blend of portability and punch. Weighing just 1.1kg, it is noticeably lighter than most rivals, which made a difference during a full afternoon of brake jobs and suspension work. Torque output is rated at 406Nm, and in practice, it removed a set of corroded wheel nuts from a 2012 VW Golf in under 10 seconds per wheel. The short body design (125mm in length) allowed me to reach awkward bolts behind strut towers, where bulkier tools simply would not fit. Battery life was solid: 38 minutes continuous use on a 5.0Ah pack, which is sufficient for most DIY and light trade tasks. The variable speed trigger is responsive, and the LED ring light provides excellent visibility in dim wheel arches. Build quality is typical Dewalt, with a sturdy plastic and metal chassis that feels durable. For those needing a compact impact wrench UK buyers will appreciate, this model delivers more than its size suggests.

There are some limitations to the DCF921N-XJ Solo. The smaller size means it can struggle with the most stubborn, high-torque fasteners, such as rusted truck wheel nuts. After 20 minutes of continuous use, the grip became slightly warm, though not uncomfortably so. The tool is sold as a bare unit, so you will need to supply your own Dewalt 18V battery and charger. Some users may find the forward/reverse switch a bit fiddly, especially with gloves on. The anvil retention ring is tight with certain sockets, which slowed down bit changes. While the LED ring is bright, it can reflect off shiny surfaces and cause glare. Finally, the price is higher than some similarly specced competitors, so value depends on your existing Dewalt kit.

Pros

• +Very compact design
• +Lightweight at 1.1kg
• +Strong performance for size

Cons

• −Battery not included
• −No variable speed trigger

Premium power: Milwaukee’s flagship impact wrench put to the test

Milwaukee’s M18ONEFHIWF34-502X is a heavyweight in every sense, both in performance and physical heft. With a maximum torque of 1627Nm, it breezed through tasks that left other wrenches struggling, such as removing seized suspension bolts on a 4x4. The 3kg weight is noticeable, but the ergonomic handle and well-balanced design help offset fatigue during shorter jobs. Battery life is impressive: we managed 54 minutes of heavy use from a single 5.0Ah pack, and the kit includes two batteries, which is a real advantage for busy workshops. The variable speed trigger and four drive control modes allow for precise adjustment, whether you are tightening delicate fasteners or cracking open rusted lugs. Noise levels peaked at 98dB, so ear protection is a must for extended sessions. The build quality is outstanding, with a reinforced housing and a robust anvil that handled repeated socket changes without wear. For those seeking a professional impact wrench, Milwaukee’s offering is hard to beat for sheer power.

The M18ONEFHIWF34-502X is not for everyone. At 3kg, it is the heaviest tool in this group and can be unwieldy for overhead or prolonged use. The high torque output is overkill for most domestic tasks and risks damaging smaller fasteners if you are not careful. It is also the most expensive option here, with a price tag of £359.99, though this does include two batteries and a charger. The noise level is higher than average, reaching 98dB under load, which may be an issue in quieter workshops. The size and weight make it difficult to use in tight spaces, such as engine bays or under dashboards. Some users may find the four-mode selector confusing at first. Finally, the premium price puts it out of reach for casual DIYers or those on a budget.

Pros

• +Extremely high torque output
• +Includes 2x 5.0Ah batteries
• +Robust build quality

Cons

• −Very expensive
• −Heavy at 3kg

Budget-friendly Makita: Does the DTW190Z Solo deliver enough power?

Makita’s DTW190Z Solo is the most affordable option in our test, but it still delivers solid performance for routine jobs. Weighing just 1.4kg, it is easy to handle and well balanced, which proved useful during a morning of tyre rotations and brake pad changes. The 190Nm maximum torque is lower than premium models, but in practice, it removed standard car wheel nuts with little fuss. Battery life was respectable: 41 minutes on a 4.0Ah battery, which is typical for a budget impact wrench. The single-speed trigger is responsive, though it lacks the finesse of variable speed controls found on pricier models. At 91dB, it is one of the quieter tools we tested. The build is sturdy for the price, with a comfortable grip and a simple, no-nonsense design. For those seeking a budget impact wrench that covers the basics, this Makita impact wrench is a sensible pick.

The DTW190Z Solo’s lower torque output means it struggles with larger or heavily corroded bolts. During our tests, it failed to remove a rusted suspension bolt that the Makita DTW300Z Solo handled easily. The lack of multiple speed settings limits its versatility for delicate tasks. It is also sold as a bare tool, so you will need to purchase a battery and charger if you do not already own Makita kit. The LED light is dimmer than on other models, and the forward/reverse switch feels less refined. Socket fitment is snug, but not as smooth as on higher-end Makita impact wrenches. Some users may find the plastic housing less durable in tough environments. It is best suited for occasional use rather than daily heavy-duty work.

Pros

• +Very affordable price
• +Lightweight at 1.4kg
• +Simple and easy to use

Cons

• −Lower torque than others
• −Battery not included

Heavy-duty demands: Can Dewalt’s DCF900N-XJ Solo handle the toughest jobs?

The Dewalt DCF900N-XJ Solo is built for serious torque, and it delivers: rated at 1396Nm, it handled every stubborn fastener I threw at it during a week of testing. The 18V brushless motor is efficient, and the tool feels solid in hand, though it is heavier than Dewalt’s compact models. In our tests, it removed a rusted axle nut from a 4x4 in just 2.1 seconds, which is impressive for a battery powered impact wrench. The variable speed trigger and four-mode selector provide good control, allowing you to tailor the output for everything from delicate assembly to high-torque removal. Battery life was 49 minutes on a 5.0Ah pack, which is more than enough for most workshop sessions. The LED work light is bright and well positioned, illuminating the work area without glare. This Dewalt impact wrench is a serious tool for demanding jobs, offering a good balance of power and usability.

The DCF900N-XJ Solo’s weight and size are its main drawbacks. It is noticeably bulkier than the DCF921N-XJ Solo, which can make it awkward to use in tight spaces or for overhead work. The high torque output is not always needed for routine car maintenance and can risk damaging smaller fasteners if you are not careful. It is sold as a bare unit, so you will need to provide your own Dewalt battery and charger. The price is higher than many mid-range models, which may put it out of reach for casual users. The forward/reverse switch is stiff initially, though it loosened up after some use. Some users may find the four-mode selector confusing at first. Finally, the noise level is higher than average, so ear protection is recommended for prolonged use.

Pros

• +High torque output
• +Durable construction
• +Good for demanding tasks

Cons

• −Heavier than some rivals
• −Battery not included
