Bosch GDS 18V-400 Cordless Impact Wrench with High Torque

Key specs include: 400 Nm maximum torque, 600 Nm breakaway torque for stubborn fasteners, 0–2,500 RPM no-load speed, 0–3,700 BPM, 1/2" square drive, weight around 1.25 kg (excluding battery), brushless motor, ABR, and compatibility with Bosch’s 18V battery system.

ABR automatically stops the tool when fasteners are loosened, preventing the bolt from dropping and reducing damage to the workpiece or tool. It’s especially handy when removing bolts in tight spots.

It uses a 1/2" square drive, which is compatible with a wide range of standard 1/2" sockets and impact-rated accessories available for most automotive and heavy-duty tasks.

The tool weighs about 1.25 kg without a battery, contributing to reduced user fatigue. Its ergonomic, compact design helps with balance and control during extended use.

Yes, it’s part of Bosch’s 18V system. Using compatible Bosch 18V batteries ensures peak performance and optimal runtime. Higher-capacity batteries will extend runtime for demanding tasks.

Ideal for heavy-duty fastener installation and removal in automotive work, suspension and chassis work, machinery maintenance, and any job requiring high torque with reliable ABR control.

Steps: 1) Ensure you’re using a compatible Bosch 18V battery and a suitable 1/2" socket. 2) Attach the battery securely. 3) Set the desired speed using the trigger. 4) Apply steady pressure to engage the bolt and squeeze the trigger to start. 5) Let ABR manage bolt release when loosening. Always wear PPE and follow site safety rules.

Wear safety glasses, gloves, and hearing protection as appropriate. Secure the workpiece, avoid over-torquing or binding, and use the correct socket to prevent slippage. Do not use damaged batteries or accessories, and follow Bosch’s safety guidelines for power tools.

Keep the tool clean and dry, inspect the drive and sockets for wear, and store it with a charged battery in a cool, dry place. Regularly check for firmware or tool updates if Bosch provides them, and protect it from moisture and dust when not in use.
