Abstract: A hand-held power tool has a main element having a tool axis, a center of gravity, and a normal axis which extends perpendicular to the tool axis and through the center of gravity. The tool axis and the normal axis define a plane of motion. A handle supported in the plane of motion such that it is movable relative to the main element. A spring unit connects the handle with the main element and includes a spring element. The handle has a handle body, a rotary element which connects the handle body and the main element. The rotary element is rotatable relative to the main element and to the handle body.

Abstract: The hand-held power tool has a vibration-damped main handle. The hand-held power tool has a device for fastening the main handle to a main element configured so that when the main element moves out of a stationary position toward the main handle the main element swivels around at least one swivel axis so that it is guided along a trajectory that extends with a slant of at least 10° relative to a flat surface, which extends through a longitudinal tool axis and which has a surface normal oriented in a normal direction perpendicular to the longitudinal tool axis. As a result vibrations with a movement component perpendicular to the longitudinal tool axis are damped as well as vibrations that induce motion of the main element in the direction of the longitudinal tool axis toward the main handle.
