Zusammenfassung:A hammer drill having an impact mechanism and a rotary drive, wherein the hammer drill is designed to rotate a tool at a speed n about a longitudinal axis of the tool and to drive it with an output impact power PS along the longitudinal axis with a striking movement is disclosed. At a working point, at least one condition is met: 1. The ratio of the output impact power PS to the speed n is at least 3.5 W/rpm; 2. Depending on the output impact power PS, the speed n is at most (PSAN−300)2/2000+150) rpm; 3. In the event of an infinitesimal change in the output impact power PS, the speed n changes by at most 0.1 rpm/W.
