If you’re after a mid‑range cordless impact wrench that doesn’t quit when you’re knocking out nuts and bolts all day, the is worth a hard look — this 18 V pro‑grade unit pushes up to 250 Nm of torque and keeps things simple in the field. What really stands out is how light and easy it is to handle — you don’t feel like you’re wrestling a brick when you’re under a car or awkward‑angled frame.

Here's the thing: the compact 1/2" drive and straight‑forward controls make this a solid choice for every day tightening or loosening on site — whether you’re changing wheels on a van or assembling steel frames — and the ABR (Auto Bolt Release) feature helps keep fastener threads from rounding out when you’re reversing out stubborn hardware.

Key Features:

• 18 V Cordless Power – You get freedom from cords without giving up torque for general mechanical and construction tasks. 
• Up to 250 Nm Torque – Enough grunt to handle medium‑duty nuts and bolts with authority. 
• 1/2″ Drive – Standard size fits a wide range of sockets for bolts from M10 to M18. 
• Auto Bolt Release (ABR) – Automatically cuts power when the fastener is freed, so you’re not overwinding or rounding threads. 
• Lightweight Build – Around ~1.2 kg (tool only) means less fatigue over a long day. 

Applications

This isn’t just a backyard tinkerer’s toy — the GDS 250‑LI impact wrench is right at home on service trucks, in fabrication shops, on scaffolding, and in workshops where you’re breaking and making bolts all day long; it’s especially handy for wheel work, chassis assemblies, and light structural fasteners.

Why Choose This Model

The bottom line is simple: this model gives you a dependable balance of power and portability. It’s not trying to be the biggest torque monster in the fleet — it’s trying to make your work easier. With compatibility across the Bosch 18 V battery platform, you can run the same batteries you already use on drills, saws, and grinders — and that matters a lot on a job site.

Technical Specifications Explained

• Battery Voltage: 18 V – Plenty of juice for consistent performance without overloading you with weight.
• Max Torque: 250 Nm – Real‑world tightening power for medium‑sized fasteners you see on automotive and structural work.
• No‑Load Speed: 0‑2400 rpm – Gives you quick spin up to get the socket moving before the impacts kick in.
• Impact Rate: ~3300 bpm – That’s how many times per minute the hammer mechanism fires — and yes, it’s what breaks stuck bolts free.
• Weight (Excl. Battery) – Around 1.2 kg keeps strain off your wrist on long tasks.

Who Should Buy This

If you’re a mechanic, builder, or tradesperson who needs solid mid‑range torque without hauling around a heavy beast, this cordless impact wrench hits a sweet spot — it’s powerful enough for most M10‑M18 fasteners, light enough to grab all day, and fits right into a Bosch 18 V kit you already use.

But if your work regularly pushes into heavy commercial or industrial fasteners beyond 250 Nm, this isn’t the torque king — you’ll want to step up to something bigger. That said, for routine service, site assembly, and general workshop use, it’s a dependable tool you’ll reach for again and again.
