Bosch GBH 18V-26 Professional Cordless SDS-plus Rotary Hammer 18 Volt (without Battery and Charger, with Carrying Case)

The Bosch GBH 18V-26 Professional Cordless Rotary Hammer (SDS-plus), bare tool is an 18 V lithium-ion machine built for professional construction and renovation work. A brushless motor drives the internal mechanism, allowing sustained operation on masonry without carbon brush wear. This model supports standard drilling, hammer drilling, and chiselling to suit common site requirements. Its main performance figure is a maximum impact energy of 2.6 J, which penetrates dense base materials efficiently. Users can apply this force to concrete, wood, and steel. Operators can also use the reverse function to back out bound bits during deep drilling.

Usability centres on the SDS-plus chuck system, which allows secure, tool-free accessory changes on site. Handling is aided by an included auxiliary handle and a soft-grip exterior for stability during use. A built-in light illuminates the immediate work area, helping visibility in low-light conditions. With a baseline weight of 3,000 g, the unit remains manageable for horizontal and overhead tasks. This bare-tool version requires an existing Bosch Professional 18 V battery system, as neither a battery nor a charger is included. The machine ships in a carrying case for organised transport.
