Bosch GBH 240 rotary hammer 0611272100

Power and performance in a compact housing

The GBH 240 series rotary hammer is a tool designed for efficient drilling in hard materials, such as concrete or masonry, as well as for lighter chiseling work. Thanks to a 790 W motor and a single impact energy of 2.7 J (according to the EPTA standard), the device offers one of the fastest drilling rates in its class. The optimized gear housing allows for rapid penetration through difficult substrates, resulting in reduced working time when installing fasteners or creating installation holes.

The tool weighs only 2.8 kg, making it lightweight and maneuverable even during overhead work or in hard-to-reach places. The SDS-plus chuck ensures quick and secure accessory changes without the need for wrenches, which is crucial during frequent changes of drill bits or chisels. Smooth speed regulation and the ability to work in both directions (right and left) provide full control over the drilling process, allowing for precise adjustment of parameters to the specific material – from soft wood to hard concrete.

Application and functionality in practice

The device proves effective not only for standard mounting hole drilling but also for creating grooves in concrete or cutting larger holes for ventilation and installations using diamond core bits. The maximum drilling diameter in concrete is 24 mm for hammer drill bits, while using core bits, up to 68 mm can be achieved. For metal and wood, the device allows for drilling holes with diameters of up to 13 mm and 30 mm, respectively.

Thanks to the Vario-Lock system, the user can freely set the chisel position, which is essential for finishing work such as removing grout or breaking ceramic tiles. The tool also features a rotation-only function, enabling precise drilling in metal or wood without the risk of material damage from impacts. The device's construction is designed to facilitate servicing – up to 85% of parts are replaceable, which extends the hammer's service life even under intensive use on construction sites.

Ergonomics and kit completeness

Work comfort is a priority in the design of this model. An additional auxiliary handle with an adjustable mounting angle allows for stable tool guidance regardless of the working direction. The depth stop (210 mm) facilitates control over the depth of the drilled hole, which is particularly important when installing expansion anchors with a specific embedment length. The tool is compatible with dust extraction systems, improving working conditions and the operator's health safety.

The set is delivered in a durable tool case, which protects the equipment during transport and ensures organization on the construction site. The package includes:

• GBH 240 rotary hammer
• Auxiliary handle
• Depth stop (210 mm)
• Durable transport case

Technical parameters such as a rated power of 790 W or impact energy of 2.7 J determine the high efficiency of the device. An impact rate of up to 4200 bpm and a rotation speed of up to 930 rpm ensure dynamic work in various materials. The SDS-plus chuck is the standard for quick accessory changes for diameters up to 24 mm in concrete (or up to 68 mm when using core bits). A net weight of 2.8 kg ensures the tool does not strain the hands during longer working sessions.

This tool is a solid choice both for professionals seeking reliable equipment for daily construction tasks and for advanced DIY enthusiasts needing an efficient hammer for renovation work in homes or apartments. Thanks to its design and high operating parameters, the GBH 240 handles most typical challenges related to processing construction materials.
