Bosch SDS-max® Demolition Hammer is a muscular tool to get tough jobs done. It provides 9.6 ft.-lbs. of impact energy and a max of 2,720 BPM, but this 14.5-AMP demo hammer weighs only 18.3 lbs. for outstanding power-to-weight performance. The tool has Vibration Control™ for all-day comfort and Constant Response™ circuitry for constant power under load.
