The Bosch GBH18V-26K 18V EC Brushless 1 In. SDS-plus Bulldog Rotary Hammer Kit has a hammer that can deliver similar power to a corded hammer - with cordless convenience. The GBH18V-26 hammer was designed with an efficient EC Brushless motor, which offers 50 percent more impact energy and greater tool runtime than previous-generation cordless hammers with brushes. The tool weighs only 7.7 Lbs. but delivers 1.9 Ft.-Lbs. of impact energy, for an outstanding impact-to-weight ratio. It also has KickBack Control, an integrated sensor to stop tool rotation in bind-up situations. It 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 kit comes with two 18V 6.0 Ah FatPack batteries, an 18V fast charger (which can charge a spent 18V 6.0 Ah battery to 80% in 35 minutes and to 100% in 55 minutes) and a carrying case.
