The Bosch GBH18 V-26 18 V EC Brushless 1 In. SDS-plus® Bulldog Rotary Hammer offers similar power to a corded hammer – with cordless convenience. It was designed with an efficient EC Brushless motor, which provides 50 percent more impact energy and greater tool runtime than previous-generation cordless hammers with brushes. It has KickBack Control, an integrated sensor to stop tool rotation in bind-up situations. Weighing only 6.3 Lbs. (tool only, not including battery), it delivers 1.9 Ft.-Lbs. of impact energy, for an outstanding impact-to-weight ratio. This tool offers an optional GDE18 V-16 dust-extraction unit, which is integrated with the tool to provide a self-contained HEPA dust solution for max mobility. The hammer also has such advanced features as Electronic Precision Control, for smoother bit starts; Vibration Control, for extended user comfort\; and Electronic Motor and Cell Protection, to avoid overheating and overload. It has an ergonomic L-shaped design for easier horizontal drilling. This is a bare tool; the battery and charger are sold separately.
