Bosch GSR 18V-45 Professional 500 RPM Keyless 900 g Black, Blue

The Bosch GSR 18V-45 Professional 500 RPM, 900 g is a compact pistol grip drill designed for battery-powered drilling and screwdriving. With a keyless chuck and a maximum idle speed of 500 RPM, this cordless drill combines a lightweight 0.9 kg build with a two-speed gearbox and an 18 V lithium-ion power source. The chuck accepts bits up to 13 mm, making the tool suitable for a variety of fastening and light drilling tasks where accessibility and maneuverability are important.

Advantages

The tool’s pistol grip design provides balanced handling for overhead and confined-space work while keeping overall weight to 900 g. The keyless chuck enables quick bit changes without additional tools. Two gears allow selection between higher torque or higher speed according to the task, and the 18 V Lithium-Ion battery ensures consistent power delivery and portability. The compact dimensions and moderate idle speed make the drill easy to control for precision screwdriving and small-diameter drilling.

How to use

Install a charged 18 V Lithium-Ion battery according to the manufacturer’s instructions. Open the keyless chuck by hand, insert the selected drill or screwdriver bit to the required depth and tighten the chuck firmly. Select the appropriate gear for the job: low gear for higher torque when driving screws, high gear for higher speed when drilling. Start at low trigger pressure to establish the bit position, then increase speed as needed. After use, release the trigger, remove the bit if required and store the tool with the battery removed or according to Bosch storage guidance.

Recommendations

For improved bit life and consistent performance, use compatible Bosch 18 V Lithium-Ion batteries and recommended bits for the material. When working in tight or overhead positions, use the lower speed/torque setting for controlled screwdriving. Regularly check and clean the keyless chuck to ensure secure bit retention and long-term reliability.
