High torque (650 Nm) for tough screwdriving applications in metal (M 12 - M 20) and concrete.Extremely robust and tough due to all-metal gearbox and metal housing.At 3.0 kg, it is one of the lightest High-Torque impact wrenches.Innovative 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 dischargePractical battery charge level indicator can be used at any time to find out how much energy is left in the battery
