The GBH 2-28 F is the strongest tool in Bosch’s 2 kg SDS-Plus rotary hammer category.
Its robust 880 W motor provides 3.2 J impact energy with an impact rate of up to 4000 bpm, ensuring fast drilling progress in concrete, masonry, wood, and metal.
The quick-change chuck system allows switching between SDS-Plus and keyless chucks for round shaft drill bits.
Safety is enhanced with KickBack Control and a Rotation Control Clutch, while Vibration Control reduces fatigue during time-intensive applications.
Additional features include reverse mode, variable speed, and Vario-Lock for chiselling angle adjustment.
Compatible with dust extraction attachments, the GBH 2-28 F is ideal for professional construction and renovation projects.
