The Baumr-AG petrol powered jackhammer is a full commercial grade unit, which utilises the highest spec motor and mechanical components, combined with a high tensile reduction gear set. This is one of the few jackhammers you are likely to find with these specs. The benefit of such a combination is a greater impact transfer with minimal loss through motor and gear cluster - a truly fantastic machine! Huge torque from the perfectly matched 49.3cc power unit allows for maximum demolition force far beyond it's lesser electric counter parts, whether it be tearing up foundations, ripping up driveways, demolishing re-enforced concrete floors or walls, breaking through solid rock or as the perfect companion while on site. The Baumr-AG petrol jackhammer also makes removing old pebble a breeze.
