Abstract:
A portable hand-held power tool (2), especially in the form of a drilling or chisel hammer, includes a drive assembly (8) located in the tool housing (10) for driving a tool spindle (4) along an operational axis (A), a first handle (16) which is rotatable around a first pivotal axis (S1) by a first handle suspension (22), a second handle (20) located on the opposite sides (14.1, 14.2) of the housing which is rotatable around a second pivotal axis (S2) by a second handle suspension (24), and spring elements for retaining the handles (16, 20) in their initial position, with the first and second handle suspensions (22, 24) extending partially circumferentially about the drive assembly (8).
