Impact Wrench Bosch GDS 18V-1000 C Professional, Package: 270x288x109 mm

The Bosch GDS 18V-1000 C Professional 1/2" impact wrench delivers high torque and selectable control for demanding fastening and loosening jobs. Equipped with BITURBO Brushless technology, the tool offers up to 1,000 Nm tightening torque and 1,600 Nm breakaway torque when used with ProCORE18V batteries. It is compact and lightweight for easy handling and is compatible with the Bosch Professional 18 V battery system.

Advantages

BITURBO Brushless motor technology provides high torque output while optimising performance with ProCORE18V batteries. Two default user modes (metal A and wood B) reduce the risk of damaged screwheads or lost fasteners by slowing or stopping the impact action; both modes are customisable through the Bosch Toolbox App. Three speed/torque settings and built-in protections (Electronic Cell Protection and Electronic Motor Protection) increase control and durability. The tool also includes an LED status indicator and a ladder clip for convenient on-site use.

Suitable for

• Tightening and removing metal bolts and nuts up to M24
• Structural steel construction and metal assembly
• Pipe fitting and vehicle maintenance
• Screwing or using lag bolts in wood construction

How to use

Select the appropriate speed/torque setting and connect a compatible Bosch 18 V battery (ProCORE18V ≥ 5.5 Ah recommended for maximum performance). Choose the user mode that matches the application — metal mode (A) for bolted connections or wood mode (B) for lag screws — and adjust mode parameters via the Bosch Toolbox App if needed. Fit the required 1/2" socket to the friction ring, position the tool squarely on the fastener and apply steady pressure while operating. For breakaway applications, start at a lower speed setting and increase as required to control reaction torque.

Recommendations

Use ProCORE18V batteries with a capacity of 5.5 Ah or higher for best torque performance. Regularly check battery and motor temperature during heavy use and allow cooling breaks to prolong tool life. Follow standard safety practices: wear eye and hearing protection, secure workpieces, and consult the user manual for maintenance and torque guidance.
