Brushless Performance
Professional torque without the cord
The Flex IW 1/2" 18.0-EC delivers up to 350 Nm of loosening torque through a brushless motor that runs cooler, lasts longer and draws less power from your battery than a brushed equivalent. Three selectable torque settings mean you can dial in the right output for the job rather than fighting a single fixed power level.
Why the IW 1/2" 18.0-EC
Four reasons professionals choose it
More control, more durability, more uptime.
-
350 Nm Loosening Power

-
EMS Motor Protection
Electronic Management System monitors load and temperature to keep the motor running longer.
-
3-Step Torque Control
Switch between 140, 170 and 250 Nm to suit the fastener - no overtightening, no stripped threads.
-
1.1 kg Tool-Only Weight
Compact and light enough to work in wheel arches for extended periods without arm fatigue.
How it stacks up
Flex IW 1/2" 18.0-EC vs. a standard cordless impact wrench
Not all cordless impact wrenches are built the same. Here is how the Flex IW 1/2" 18.0-EC compares to a typical mid-range alternative on the specs that matter in a professional setting.
| Feature | DetailerSA | Alternative |
|---|---|---|
| Brushless motor | Yes | No |
| Electronic Management System (EMS) | Yes | No |
| 3-step torque settings | Yes | No |
| 1/2" square drive compatibility | Yes | Yes |
| Integrated LED work light | Yes | Yes |
| Battery included | No | Yes |
Built for the Workshop
Tough housing, smart protection
Die-cast aluminium gearbox housing, an electronic quick-acting brake and Flex's EMS electronic management system work together to protect both the tool and the fastener. Whether you are pulling wheels on a customer's car or running fasteners in a busy tyre fitment bay, the IW 1/2" 18.0-EC is built to handle the pace.

Questions
Frequently asked
Does this kit include a battery and charger?
No. This is a tool-only listing. The IW 1/2" 18.0-EC is compatible with all Flex 18V battery packs (2.5 Ah, 5.0 Ah and 8.0 Ah), but the battery and charger must be purchased separately.
What is the maximum torque output?
The wrench has three forward torque settings: 140 Nm on setting 1, 170 Nm on setting 2 and 250 Nm on setting 3. Maximum loosening torque reaches 350 Nm.
What socket drive size does this wrench use?
It uses a 1/2" square-drive tool holder, which is the standard sizing for most automotive impact sockets. Any quality 1/2" impact socket set will fit directly.
What is Impact Control and when should I use it?
Impact Control is Flex's feature for precise positioning of screws and fasteners. It is particularly useful when working with small or sensitive fasteners where overtightening would strip threads or crack plastic components. Select the appropriate lower torque setting alongside Impact Control for the best result.
How does Speed Command work in practice?
Speed Command gives you three selectable speed and torque profiles. Use setting 1 (140 Nm) for delicate or small fasteners, setting 2 (170 Nm) for general work and setting 3 (250 Nm) for heavy-duty loosening and tightening. The 350 Nm loosening torque is available to break seized fasteners free.
How heavy is the wrench and will it cause fatigue during extended use?
Without a battery, the tool weighs 1.1 kg. Overall dimensions are 140 x 75 x 240 mm. The ergonomic non-slip soft-grip handle is designed to reduce fatigue during longer sessions. The actual in-hand weight will increase depending on the battery pack chosen.
What does the integrated LED lamp do?
The LED lamp illuminates the work area when you are working in wheel arches, undercarriage areas or low-light workshop spaces. It has a persistence function, meaning it stays on briefly after you release the trigger so you can see the fastener clearly before and after operation.
Is the gearbox housing durable enough for professional workshop use?
Yes. The gearbox housing is constructed from die-cast aluminium with a protective cap, which is the standard in professional-grade cordless impact tools. It handles the mechanical stress of repeated high-torque impacts and resists the knocks of a busy workshop environment.
