Rotary hammer Bosch GBH 2-28 F 0611267600

Power and performance in the 2 kg class

This tool positions itself as the most powerful model in the segment of rotary hammer drills weighing approximately 2 kg with an SDS-plus chuck. At its heart is a motor with a rated power of 880 W, which generates an impact energy level of 3.2 J. This parameter is not just a dry number – it translates directly into the speed of work progress in hard mineral materials such as concrete or natural stone. Thanks to this, the device handles drilling holes with a diameter of up to 28 mm in concrete, making it a versatile tool for both assembly work and heavier finishing tasks.

It is worth noting the design of the impact mechanism, which allows for reaching up to 4000 impacts per minute. This high frequency, combined with appropriate impact force, ensures the fastest drilling rate in its class. For an installer, this means less time spent per hole, and for the end customer – faster completion of the renovation. The tool offers three operating modes: hammer drilling (main mode), drilling without impact (for wood and metal), and a chiseling function (impact only), which eliminates the need to own several different machines for typical construction tasks.

Safety and continuous working comfort

Working with rotary hammers often involves significant strain on the operator's wrists and hands. This model utilizes a Vibration Control system, which reduces vibration levels by 27% compared to previous models. Less vibration means less fatigue during long working sessions and greater precision when guiding drill bits. Additionally, the tool is equipped with the KickBack Control function. This is an intelligent safety system that reacts in the event of sudden drill bit blockage or jamming in the material. Instead of a violent kickback of the tool, this mechanism limits the torque, protecting the user from injury and preventing damage to the device itself.

Another element increasing safety is the overload clutch and the ball sleeve that prevents cable breakage during a sudden jerk. The rotating brush holder guarantees identical working power regardless of the direction of rotation – whether during drilling or unscrewing jammed drill bits (reverse function). Smooth speed regulation allows for precise starting of drilling without the risk of the drill bit jumping out of the material, which is crucial during finishing work or the installation of delicate elements.

Application and set completeness

The device is dedicated to professional use in concrete, masonry, wood, and metal. The maximum drilling diameter in steel is 13 mm, and in wood, it reaches up to 30 mm. Thanks to the interchangeable drill chuck (a 13 mm keyless chuck is included in the set), the tool can be quickly adapted for non-impact drilling in softer materials without the need for SDS-plus bits. The Vario-Lock system allows the chiseling accessories to be rotated to any angle, facilitating precise grooving of plasters or cutting materials at an angle.

The set is delivered with the necessary accessories for immediate work: a transport case for easy organization and storage, an additional handle for better control during one-handed operations, and adjustable or double-sided depth stops. The equipment also includes dust protection cloth to protect against dust during drilling and interchangeable chucks – both SDS-plus for heavy impact work and a universal keyless chuck for precision work in wood or metal. The set is completed by an instruction manual containing detailed technical tips.

The tool is also characterized by a longer service life – the manufacturer indicates an increase of 25% compared to other models in this class, which translates to lower operating costs and less frequent need for servicing the steel gear mechanism. The entire unit weighs only 3.1 kg, which, while maintaining high power, makes it one of the lightest solutions with such high parameters on the professional market.
