Background

The Bosch 11241EVS is a rotary hammer that was first manufactured by Robert Bosch GmbH, a German company, in 1999. It is designed for heavy-duty applications such as drilling and chiseling concrete. The rotary hammer uses a 120V AC, 60Hz power source and its motor power is 850W. It operates at a no-load speed between 120-250 RPM and delivers blows per minute ranging from 1,000-2,400 in hammer/rotation mode and 1,200-2,800 in hammer-only mode. The tool measures 21 inches in length and weighs 15 lbs.

The 11241EVS employs an SDS-Max bit system, a feature that allows for tool-free bit changes. The tool offers two modes, namely rotary hammer and hammer-only, which can be selected using the dual-mode selector. The variable speed dial permits controlled starts and chipping, providing an adaptable experience. The tool features constant response circuitry that enables soft starting and maintains speed under load. A distinctive feature of this rotary hammer is the Turbo Power, which allows it to deliver 20% more power in hammer-only mode. For dust protection and efficient energy transfer, it includes a rotating brush plate. The ServiceMinder light is an added feature that indicates when maintenance is due after 8 hours of use.
