Bosch GSB 20-2 850 W 2060 RPM

The Bosch GSB 20-2 is an AC-powered percussion drill designed for general-purpose drilling and light hammering tasks. With a rated input power of 850 W and a maximum no-load speed of 2060 rpm, this compact tool delivers sufficient torque for drilling in wood, metal and masonry. It drills up to 18 mm in concrete using the hammer function, up to 40 mm in wood and up to 13 mm in steel, while weighing approximately 2.6 kg. Its narrow body (about 90 mm width and 336 mm depth) improves access in confined workspaces and contributes to easier handling during extended use.

Advantages

The drill combines relatively high input power with a compact, ergonomic form factor that helps balance performance and accessibility. Low weight and compact dimensions reduce user fatigue and make the tool suitable for overhead work and tight installation spaces. A 13 mm keyed/quick-change chuck capacity accommodates a wide range of drill bits and accessories for different materials. Consistent speed up to 2060 rpm supports efficient drilling progress across common construction and renovation tasks.

Suitable for

• Drilling holes in concrete and masonry (up to 18 mm with hammer action)
• General woodworking tasks (up to 40 mm)
• Metal drilling and light fabrications (up to 13 mm in steel)
• Installation and assembly tasks in confined spaces
• Home renovation and professional maintenance work

How to use

Before use, ensure the tool is disconnected from the mains and select the appropriate drill bit for the material to be worked. Secure the bit in the chuck and tighten according to the chuck type. For masonry, engage the hammer function; for wood and metal, use the rotary mode. Start drilling at low speed to position the bit, then increase to the required speed up to the maximum 2060 rpm. Apply steady, moderate pressure—avoid excessive force that can overload the motor or damage the bit. After completing the task, allow the motor to cool before prolonged continuous operation and store the drill in a dry place.

Recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection and dust mask) when drilling different materials. Match drill bits to the material and check bit condition before each use. For prolonged drilling in dense materials, periodically withdraw the bit to clear chips and reduce heat build-up. When working overhead or in tight spaces, maintain a firm grip and consider using an auxiliary handle or support to improve control and reduce vibration exposure.
