GBH 18V-28 DC Professional: Further information
Product Highlights

The GBH 18V-28 DC Professional is Bosch’s powerhouse in the D-handle rotary hammer class: It delivers powerful performance, even stronger than the corded GBH 2-28, with its brushless motor, providing 3.4 J of impact energy and an optimised power-to-weight ratio of 1.1 J/kg. For highly convenient, dustless drilling, the additional and extremely lightweight GDE 28 D Professional dust extractor, that features a filter cleaning mechanism for constant suction power, can be easily attached. Additionally the GBH 18V-28 DC offers Vibration Control and KickBack Control, which senses sudden loss of tool control. In case of e.g. a canted drill, it instantly shuts the rotary hammer down in order to minimise hand and arm injuries.
Equipment & Application

This rotary hammer is perfect for hammer drilling in concrete, stone and masonry and thanks to its D-handle design ideal for vertical and downward drilling. Additionally the GBH 18V-28 DC is compatible with all Bosch Professional 18V batteries and chargers (Professional 18V System).
Additional Information

The GBH 18V-28 DC Professional is connected-ready for integration into the Bosch Toolbox App and features a tool hook for hanging the rotary hammer during interruptions at work.
