Bosch Power Tools DH1020VC demolition hammer

The DH1020VC from Bosch Power Tools is a 25-pound demolition hammer with an extended air cushion in the hammer mechanism. The de-coupled main handle reduces vibration in two locations inside the tool. It produces 17 foot-pounds of impact energy. A 12-position Vario-lock allows users to rotate and lock the chisel into 12 different working positions to find the optimal working angle, while a variable-speed dial reduces the impact rate and impact energy when controlled chiseling is required. Constant-response electronics offer soft-start functionality, overload protection and constant motor speed with varying loads. A service light indicates the need for the carbon brushes to be changed with about eight hours of brush life remaining.
