The Bosch BH2760VCB Brute Breaker Hammer weighs just 63 lb. but delivers 1000 BPM and 35 ft-lb. of impact energy, making it a powerhouse with the best concrete removal rate in its class. It is ready for such heavy-duty applications as foundation work or pipe laying. The breaker hammer with included cart is portable, running on any 115/120V AC/DC, 15 Amp outlet or 2500 watt portable generator - no compressor needed. With Bosch's Active Vibration Control for more operator comfort, users can work longer to get more done. Service Minder Brush System shuts it off when it needs preventative maintenance.
