Bosch GSB 18V-28 Akku-Schlagbohrschrauber 28500 RPM Black, Blue, Red

The Bosch GSB 18V-28 is a cordless impact power screwdriver designed for demanding fastening and drilling tasks. Powered by an 18V Lithium-Ion battery, it combines compact dimensions (78 mm width, 202 mm depth, 204 mm height) with a pistol handle for controlled operation. The tool offers two gears with adjustable speed: 500 RPM in first gear and 1900 RPM in second gear, while the maximum idle speed reaches up to 28,500 RPM, making it suitable for a range of materials and screw sizes. Integrated light and reverse function support precise work in confined or poorly lit areas.

Advantages

The cordless design and 18V battery provide mobility without compromise on torque and performance. The pistol handle improves grip and reduces user fatigue during prolonged use. Two-speed gearbox and adjustable speed control allow accurate matching of speed and torque to the task. Built-in light enhances visibility at the work point, and the reverse function simplifies screw removal and repositioning. Compact dimensions and a weight of approximately 1.2 kg make the tool easy to handle and transport.

Suitable for

• Driving and removing screws in wood, metal and composite materials

How to use

Install a charged 18V Lithium-Ion battery according to the tool and battery manufacturer instructions and secure the chosen drill or screwdriver bit in the chuck. Select the appropriate gear for the task: use the first gear and lower speed settings for controlled screw driving and delicate materials, and the second gear for faster drilling or larger fasteners. Use the adjustable speed trigger to gradually increase torque during docking and avoid sudden jumps. Activate the built-in light when working in low-light conditions. Use the reverse function to remove screws or to back out a bit if necessary. Follow basic safety measures: wear eye protection and secure the workpiece before operating the tool.

Recommendations

For best results, use high-quality bits appropriate for the fastener and material, keep the battery charged and stored according to the battery manufacturer guidelines, and perform routine maintenance such as cleaning vents and checking the chuck for secure bit retention. When working on metal or masonry, select suitable drill bits and adjust speed and pressure to avoid overheating.
