The Bosch 11265EVS 1-5/8-In. Spline Combination Hammer features a powerful 13.0-amp motor and has a dual-mode selector for combination versatility – rotary hammer or hammer-only mode. Concrete contractors will appreciate the production in drilling and chiseling applications. Providing 6.5 ft.-lbs. of impact energy, the tool weighs only 15.1 lbs., for a top performance-to-weight ratio. Constant Response™ circuitry allows for smooth starts and constant load under pressure, and an integral clutch helps to minimize adverse torque reaction. The hammer's 12-position Vario-Lock™ helps to optimize chiseling angles. Bosch's Vibration Control™ in the hammer mechanism and grip area provide improved user comfort. The Auto-Max™ variable-speed dial allows users to adjust tool settings based on the application and material they're tackling. The hammer has a Service Minder™ light indicating when preventative maintenance is needed.
