Endless power and absolute controlUp to 50% faster work rate due to higher single impact energy and 100% more lifetime (compared to predecessor GBH 36 VF-LI)Absolute control if the drill bit jams thanks to Bosch KickBack Control (KBC) and in sensitive materials thanks to Bosch Electronic Precision Control (EPC)Comes complete with a keyless chuck, making it also suitable for straight-shank drill bits in wood and metalWhy this tool?Vibration Control for low user fatigueLED work-light for an optimum view of the work positionUp to 240 holes in concrete with one battery charge (diameter 6 x 40 mm)3 functions: drilling, hammering, chiselingInnovative COOLPACK batteries ensure optimum heat dissipation and therefore increase lifetime by up to 100% (cf. Li-Ion batteries without COOLPACK)Bosch Electronic Cell Protection (ECP): protects the battery against overload, overheating and deep dischargeFaster than average charging time: Battery charged to 80% after only 25 minutes
