Perforator Bosch GBH 2-28 Professional

The Bosch GBH 2-28 Professional is a compact rotary hammer designed for demanding drilling and chiselling tasks. It is driven by an 880 W motor that delivers up to 900 RPM and an impact energy of 3.2 J, enabling efficient work in concrete and masonry. The tool uses an SDS Plus chuck for quick bit changes and supports drilling in concrete up to 68 mm. At 2.9 kg and with a 4 m power cord, the perforator balances portability and performance while maintaining a compact footprint.

Advantages

The GBH 2-28 Professional combines a powerful motor and high impact energy with a lightweight design to reduce operator fatigue during extended use. The SDS Plus system ensures fast and secure bit changes without additional tools. Its compact dimensions and moderate weight improve maneuverability in confined spaces, and the robust build is suitable for frequent use on construction sites and renovation projects.

How to use

Select the correct SDS Plus bit for the intended material and secure it in the chuck until it locks. Set the appropriate operating mode (drilling, hammer drilling or chiselling) according to the task. Hold the tool with both hands, maintain steady pressure without forcing, and allow the impact energy to do the work. For deep holes, withdraw occasionally to clear debris. After use, disconnect from the mains and clean the bit and tool housing before storage.

Usage recommendations

Use personal protective equipment such as safety glasses, ear protection and dust mask when drilling or chiselling. For best results in reinforced concrete, use carbide-tipped SDS Plus bits and consider a slower feed rate. Regularly inspect and replace worn bits to maintain drilling efficiency and prolong tool life.
