The Bosch 11245EVS rotary hammer features an SDS-Max drive system, and its powerful 14 amp motor provides unmatched drilling performance. The hammer includes two modes of operation: hammer/rotation and hammer-only. The tool's electro-pneumatic impact system maximizes impact force and minimizes vibration, while the 12-position Vario-Lock helps optimize the work angle. In addition, the hammer's electronic feedback circuitry maintains maximum performance levels at all times. The ServiceMinder light indicates the need for service eight hours prior to tool shutdown, while the improved tool holder ensures advanced heat treatment and dust-seal protection for long life. Includes 360-degree auxiliary handle and case.
