Unsurpassed combination of power and weight Best power-to-weight ratio in its class Up to 115 holes in concrete (6 x 40 mm) with one battery charge due to efficient Bosch EC motor Pneumatic hammer mechanism, optimised for drilling holes of 6-10 mm in concrete (max. 18 mm) Unique Bosch Premium lithium-ion technology for 400% longer lifetime and unbeatable battery runtime Bosch Electronic Cell Protection (ECP): protects the battery against overload, overheating and deep discharge Bosch Electronic Motor Protection (EMP) protects the motor against overload and ensures a long lifetime Bosch “Flexible Power-System”: unique choice of 18 volt batteries with 3.0, 2.6, 1.3 Ah for individually adapting the runtime and weight to the particular application range. Practical battery charge level indicator: constantly shows how much energy is left in the battery integrated LED light for illuminating the work area, even in dark places Bosch Hyper Charge: due to the rapid charging process, the batteries are charged to 75% after just half of the charge time No memory effect: the battery can be charged regardless of the charging state at any time, without damaging the cells EC motor : more energy efficient 3 mode hammer (drilling, hammer drilling and chiseling) *Battery Not Included - batteries & charger sold separately.
