Bosch 18V EC Brushless 1" SDS-Plus® Bulldog™ Rotary Hammer (Bare Tool) - Mod. GBH18V-26

When put to the drilling test in concrete, the CORE18V battery enabled extra power in the GBH18V-26 rotary hammer, delivering up to 32% more holes, even in extreme cases, than previous-generation 18V 6.0 Ah battery. With its efficient EC Brushless motor, the hammer weighs only 6.3 Lbs. (tool only, not including battery) but powers 1.9 Ft.-Lbs. of impact energy. It also has KickBack Control, an integrated sensor to stop tool rotation in bind-up situations; Electronic Precision Control, for smoother bit starts; and Vibration Control, for extended user comfort. This tool offers an optional GDE18V-16 dust-extraction unit, which is integrated with the hammer to provide a self-contained HEPA dust solution for max mobility. The cells in the CORE18V carry more energy density than the previous-gen cells, and they are laser-welded and rail-connected for high-current efficiency. The 1.8 Lbs.
