The Bosch GBH18V-26K24 kit pairs the CORE18V GBA18V63 18V 6.3 Ah Battery – the best-built battery on the planet* – with the 18V EC Brushless SDS-plus® Bulldog™ 1 In. Rotary Hammer to deliver more power in a lightweight, cordless tool. 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. They deliver performance comparable to competitive batteries up to 35% larger. The 1.8 Lbs. CORE18V is backward and forward compatible with all Bosch 18V tools and features the Bosch-exclusive CoolPack 2.0, which is an advanced configuration that provides up to 35% more cooling effect than predecessor batteries. The included Bosch BC1880 18V Fast Charger can charge a spent CORE18V to 80% in 41 minutes and to 100% in 55 minutes. *vs. leading power tool competitors
