A handheld machine tool, in particular an impact driver, having a drive train for driving a tool receptacle, provided for receiving a tool, in particular a screwdriver tool, about a rotation axis, wherein the drive train has a drive motor, an output shaft element, on which the tool receptacle is arranged, and a drive shaft, which is drivable by the drive motor, for driving the output shaft element, wherein the output shaft element is rotatably mounted by means of an output pivot bearing and the drive shaft is rotatably mounted by means of a drive pivot bearing about the rotation axis in respect of a machine housing, and wherein the output shaft element is rotatably mounted by means of a shaft bearing arrangement on the drive shaft about the rotation axis. The shaft bearing arrangement has at least two shaft bearings, which are arranged adjacent to each other in relation to the rotation axis and differ by at least one mechanical property.
