Like a jackhammer in your hands, the Bosch 11316EVS SDS-Max Demolition Hammer will crush, break and pulverize masonry and concrete of all kinds. The powerful 14 amp motor provides up to 18.4 ft-lbs. of impact energy, packing a punch like a prize fighter, and the integrated Constant Response Circuitry helps maintain consistent motor speeds even under the heaviest loads. Every job is different, and sometimes it’s not just raw power you need. The 11316EVS features a variable speed trigger that allows you to work with more precision when needed, and the advanced handle design will provide all day comfort no matter what size the job. Bosch has also added an integrated Service Minder system that alerts you when the tool needs servicing, helping to prevent damage and extend the life of the hammer.
