The Bosch BH2770VCD Brute turbo breaker hammer delivers the best concrete removal rate in its class, impressive for a tool that weighs just 63 pounds. Providing 1000 bpm and 43 ft-lb of impact energy, this tool can handle heavy duty applications such as outdoor asphalt work or indoor foundation removal. The breaker hammer with included deluxe cart is fully mobile and doesn't need a compressor, running on any 115/120V AC/DC, 15 A outlet or 2500 W portable generator. The Active Vibration Control system includes a longer air cushion in the hammer mechanism, which substantially reduces vibration levels at their source. Shock-mounted handles complete the vibration control system providing contractors with the lowest vibration levels possible without adding any size or weight to the tool.
