The Bosch GSR 18V-21 Professional is a cordless power screwdriver designed for tradespeople and DIY users who need a compact, high-speed tool. Powered by an 18V Lithium-Ion battery, it delivers a maximum no-load speed of 1800 RPM and includes a pistol-handle form factor for comfortable grip and control. The tool integrates a 21-position gearbox for precise torque selection and comes in a compact housing measuring 78 mm wide, 198 mm deep and 204 mm high, with a net weight of approximately 1.2 kg. The unit is finished in Black and Blue and includes one battery for immediate use.

Advantages

The cordless design offers freedom of movement without a power cable and the 18V battery delivers consistent power for drilling and driving tasks. The 21-position gear selection enables controlled torque application, reducing the risk of overdriving screws. A high idle speed of 1800 RPM supports fast screw insertion and efficient drilling in soft to medium materials. Its compact dimensions and moderate weight improve accessibility in confined spaces and reduce operator fatigue during extended use.

How to use

Before first use, charge the supplied 18V Lithium-Ion battery according to the battery charger instructions. Insert a compatible screwdriver or drill bit into the chuck and ensure it is securely clamped. Select the appropriate torque/gear setting from the 21-position selector for the material and fastener size. For driving screws, start at a lower torque and increase as needed to prevent stripping. Use the variable speed trigger to control rotation; apply steady pressure and keep the tool aligned with the screw or drill hole. After use, remove the bit, switch the tool off, and store it in a dry place.

Recommendations

Use appropriate personal protective equipment, such as safety glasses and gloves. For harder materials, choose the correct drill bits and consider pre-drilling pilot holes. Regularly check and maintain battery charge and store batteries at moderate temperatures. Follow manufacturer guidance for battery charging cycles and disposal.
