The BOSCH SDS-Max® Demolition Hammer rips through all types of masonry, brick, block and asphalt for maximum efficiency on all your tear downs and remodels. The motor delivers 12.4 foot/pounds of impact energy to bore through all types of materials. The Bosch electric demolition hammer's 14-Amp motor runs up to 1890 bpm with variable speed controls so you can manage how much force you need. Constant Response™ circuitry protects the motor from overheating, maintains a consistent speed and has a soft start feature to give you improved accuracy and precision. A Service Minder™ light lets you know when maintenance is needed. A padded rear handle absorbs shock to reduce impacts on your hands, wrists and shoulders. A 360-degree auxiliary handle included with the Bosch demolition hammer allows for more movement and increases your leverage at awkward angles. The Vario-Lock™ feature enables you to rotate the tool into 12 different positions while in chisel mode for greater convenience. Bits can be changed quickly and easily without any tools and automatic bit locking keeps them in place while you're working. Dust protection tube improves air quality and keeps debris out of your eyes.
