Power screwdriver Bosch GSR 18V-55 Professional, 1800 RPM, Black/Blue
The Bosch GSR 18V-55 Professional is a cordless power screwdriver with a pistol-handle design, designed for drilling and screwing in a range of materials. It delivers up to 1800 RPM no-load speed and a minimum torque of 28 N⋅m, powered by an 18V lithium-ion battery. Compact dimensions (78 mm width, 179 mm depth, 207 mm height) and a weight of approx. 1 kg make the tool easy to hold and manoeuvre for repetitive tasks or work in confined spaces.
The GSR 18V-55 combines cordless freedom with a high no-load speed for fast screwdriving and drilling. Its pistol-handle ergonomics reduce user fatigue and improve control during prolonged use. A 21-step gearbox allows precise torque and speed selection for different materials and fastener sizes. The battery-powered design removes cable restrictions and supports use in locations without mains supply.
Fit an appropriate screwdriver or drill bit into the chuck and ensure it is securely tightened before operating. Select the required gear/torque setting on the gearbox according to the fastener and material. Hold the tool with a firm grip on the pistol handle, position the bit perpendicular to the work surface, and apply steady pressure while starting the tool. Increase speed up to the required level and release the trigger to stop. Recharge or replace the battery as indicated by the battery management system and follow standard safety practices such as wearing eye protection and securing loose clothing.
Use lower torque settings for small screws and delicate materials, and higher settings for larger fasteners or tougher materials. For consistent hole quality when drilling, start at low speed to centre the bit, then increase to full speed. Store the tool and batteries in a dry environment and follow the battery manufacturer’s charging instructions to preserve battery life.
