Abstract

The invention refers to a hand-held power tool (10) having a tool housing (16) and a quick-change working head (50) releasably attachable to a front part (16b) of the tool housing (16). The working head (50) comprises an axial input adapter (52) connectable to a tool shaft (18) of the power tool (10), an axial output adapter (54) connectable to a working element (12) of the power tool (10) and a transmission arrangement (56) with a specific transmission ratio (i), functionally located between the axial input adapter (52) and the axial output adapter (54) and making the axial output adapter (54) rotate at a given speed depending on the rotational speed of the axial input adapter (52) and the transmission ratio (i) of the transmission arrangement (56). It is suggested that the working head (50) comprises magnetic elements (58) and the front part (16b) of the tool housing (16) comprises respective magnetic elements (60). The magnetic elements (58) magnetically interact with the respective magnetic elements (60) once the working head (50) is close to the front part (16b) of the tool housing (16). The magnetic interaction between the magnetic elements (58) and the respective magnetic elements (60) ensures that the working head (50) is firmly held in respect to the front part (16b) of the tool housing (16) in an axial direction extending parallel to a rotational axis (30) of the axial input adapter (52).
