Built for fasteners that refuse to move
This wrench is aimed at one clear problem: bolts that a normal cordless driver cannot shift without drama. With a claimed 3100N·m of torque and a 3/4-inch square drive, it sits in the heavy-duty end of the AliExpress UK tool range rather than the light DIY category.
The weight and size tell the same story, because this is a 5.1KG tool designed for leverage, not pocket-friendly handling. That makes it more relevant for tyre work, construction hardware, and maintenance jobs where brute force matters, so what does that mean once you start using it?
Brushless power and why it matters on site
The brushless motor is the main quality marker here, since it typically runs cooler, wastes less energy, and avoids the wear associated with brushed motors. In practical terms, that usually means steadier output over longer sessions and less drop-off when the fastener load gets serious.
Users also tend to value the LED light and stepless speed control because they make the tool easier to manage in darker garages and tighter spaces. The four forward gears and four reverse gears, including reverse auto-stop, give it more control than a single-speed impact wrench, which becomes important when you are working near finished surfaces.
Makita 18V battery compatibility without the cable clutter
This model is sold without a battery included, but it is compatible with Makita 18V B-series lithium packs such as BL1830B, BL1840B, and BL1850B. That is useful if you already run a Makita ecosystem, because it reduces duplication and keeps the setup cleaner than a mains-powered tool.
The compatibility notes matter, though, because it does not work with G-series packs or older Ni-Cd batteries. If you have the right 18V B-series pack in the 2.0Ah to 5.0Ah range, you get a cordless setup that is far easier to move around a workshop or driveway, and that flexibility is where the value starts to show.
Where the 3/4-inch drive makes sense
A 3/4-inch square drive is a clue that this tool is intended for larger sockets and tougher jobs than a standard 1/2-inch impact wrench. It is a better match for heavy equipment maintenance, wheel nuts that have been over-tightened, and structural fixings where a compact driver would feel underpowered.
The tungsten steel shaft and wear-resistant build language suggest a focus on durability rather than finesse, which suits its role. Real customer feedback is consistent with that positioning, with repeated mentions of strong torque and robust performance, so the next question is whether the design is practical for everyday use?
What to expect in real workshop use
The reverse auto-stop function is one of the more useful details because it can help prevent fasteners from disappearing into the abyss once they break free. That is a small feature on paper, yet it makes a noticeable difference when you are working alone and want cleaner control.
At this weight, it will not feel nimble during overhead work or long one-handed sessions, and that is the trade-off for its power class. For users who need a cordless impact wrench that can replace a more cumbersome pneumatic setup in many situations, this Gisam model offers a credible middle ground between portability and force.
Who gets the most from it?
- Garage users dealing with stubborn wheel bolts and suspension hardware
- Workshop teams that already use Makita 18V batteries
- DIY users who need a high-torque tool for occasional heavy jobs
