The Bosch DH1020VC SDS-max® Demolition Hammer features an in-line design, which is ideal for handling downward or vertical chiseling jobs. This hard-hitting hammer delivers a best-in-class 17.0 ft.-lbs. of impact energy for superior concrete removal. The hammer provides maximum chipping and chiseling muscle in a 15.0-AMP tool that weighs only 25.1 lbs. for professional power and terrific performance-to-weight ratio. The DH1020VC provides Constant Response™ circuitry for constant load under pressure as well as smooth starts. And it has a Vario-Lock™ positioning feature, which allows the user to rotate the chisel for maximum working angles.
