When you have to work in confined spaces, every millimetre counts, so you need a tool that fits where others do not, without compromising on power or control. The PRO GSB12V-31 delivers exactly that: its head length is only 159 mm, making it 15 per cent shorter than the previous model and providing better access in confined spaces. Its brushless motor and new gearbox deliver strong and consistent performance, while the improved soft torque of 18 Nm provides the power needed for demanding tasks. Thanks to the clear battery indicator, you always know how much runtime is left: this helps you plan your work without interruptions. The compact and lightweight design reduces fatigue when working overhead or in confined spaces, and the soft grip and ergonomic shape add comfort during extended use. The integrated LED light provides good visibility in dim conditions, and compatibility with Bosch 12-volt batteries ensures reliable runtime and smooth charging. Compact, strong and easy to handle: the PRO GSB12V-31 lets you work smarter in every situation.
