Remove concrete and other substrates and materials thoroughly and efficiently using the Bosch SDS-MAX® Demolition Hammer. The 13 A motor delivers up to 9.6 foot/pounds of pressure while the padded rear handle and Active Vibration™ control let you operate the tool with less fatigue. Constant-Response™ circuitry protects against overload and helps to ensure a smooth start from the Bosch 13 A electric demolition hammer every time. A Vario-Lock™ positioning system holds chisel bits at one of a dozen possible angles and also enables quick, easy and tool free bit exchanges. The Auto-Max™ variable speed increases and decreases the bpm rate as needed for the job at hand. A handy Service-Minder™ light reminds you to perform preventative maintenance. This variable speed demolition hammer also features a 360-degree handle for overhead operation and an 8' cord with turret for added flexibility.
