Bosch GDS 18V-350 18v Cordless Brushless 1/2" Impact Wrench
The Bosch GDS 18V-350 is an 18V cordless brushless impact wrench designed for professional bolting applications where both power and compact dimensions are essential.
Weighing just 1.1 kg (excluding battery) and measuring 131 mm across the head, this impact wrench is built for use in confined spaces without sacrificing capability. The brushless motor delivers up to 350 Nm of torque, with a maximum breakaway torque of 560 Nm, making it well suited to loosening stubborn or corroded fasteners. The 1/2" square drive with friction ring and thru hole accepts a wide range of standard impact sockets.
Three selectable torque levels — 85 Nm, 200 Nm, and 350 Nm — allow precise control across different bolt sizes from M10 to M18. This makes it equally capable of delicate thread work and heavy-duty fastening. The variable impact rate reaches up to 3,400 bpm at the highest setting, delivering fast, efficient results across a range of applications.
Suitable for metal fabrication, HVAC installation, scaffolding, and automotive work, the GDS 18V-350 handles everything from routine bolting to machined screw assembly. The slim, soft-grip handle reduces fatigue during prolonged use, and the energy-efficient brushless motor helps extend runtime between charges on a compatible 18V Bosch battery.
Features and Benefits:
• Three torque settings (85 Nm, 200 Nm, 350 Nm) for controlled fastening across different bolt sizes
• Compact 131 mm head size and slim handle for access in restricted spaces
• Brushless motor for improved efficiency and extended battery runtime
• 560 Nm breakaway torque for removing seized or corroded fasteners
• 1/2" square friction ring and thru hole for compatibility with standard impact sockets
• Lightweight at 1.1 kg (excl. battery) for reduced operator fatigue

Battery AH Explained
The best way to describe battery amp hour is that this is effectively the size of your fuel tank, the more amp hours your battery has then the longer the battery will last between charges. More amp hours does not increase the power of a given tool.
Battery Voltage Explained
A tool with a higher voltage than another is a bit like choosing an engine in a car, the higher voltage will generally mean higher power & performance. As with cars though a bigger engine does not always translate to better performance so it is important to compare the specifications of tools at different voltages between different manufacturers.
