Chave de impacto Bosch GDS 18V-1050 H 3/4" 1750 rpm 1700 N·m

The Bosch GDS 18V-1050 H 3/4" impact wrench is a cordless, battery-powered tool designed for high-torque fastening and loosening tasks. Equipped with a brushless motor and an adjustable speed control, it delivers up to 1700 N⋅m of maximum torque and an idle speed of 1750 RPM. The 3/4" drive size accommodates heavy-duty sockets while the compact housing (266 mm x 287 mm x 97 mm) and a weight of approximately 2.9 kg make it manageable on job sites and in confined spaces.

Advantages

The brushless motor increases efficiency and reduces maintenance compared with brushed alternatives, while adjustable speed and a reversible function provide control and versatility for varied fastening requirements. The 3/4" drive ensures compatibility with a wide range of sockets used in automotive, industrial and construction applications. Its battery operation removes the need for cords, improving portability and allowing use in locations without direct power access.

Suitable for

• Removing and installing wheel nuts and large bolts in automotive and commercial vehicles
• Heavy machinery assembly and maintenance
• Construction site bolted connections and structural fastening

How to use

Ensure the battery is charged and correctly inserted before operation. Select an appropriate socket for the 3/4" drive and secure it to the impact wrench. Choose the required direction (forward or reverse) and set the speed control according to the task — lower speeds for controlled loosening or precise fastening, higher speeds for rapid operation. Apply the tool squarely to the fastener to avoid socket slippage and maintain firm pressure during use. After completing the task, remove the battery and store the tool and sockets in a dry place.

Recommendations

Use impact-rated sockets and accessories to prevent damage. Wear appropriate personal protective equipment such as safety glasses and hearing protection. For repetitive or high-torque applications, monitor battery temperature and allow cooling periods to preserve battery life and tool performance.
