    Abstract: A hand-held power tool includes a housing, in which at least one drive unit configured to drive a tool holder is arranged. The tool holder is designed to hold an insertable tool. The hand-held power tool includes an alignment apparatus having a control unit and at least one luminous element arranged on the housing. The alignment apparatus is designed to determine, in real time, during operation of the hand-held power tool, a current deviation of a selectable machining angle, which is selected via the control unit and which is formed between the insertable tool inserted in the tool holder and a workpiece surface that is to be machined, from an actual inclination angle between the insertable tool inserted in the tool holder and the workpiece surface to be machined, and to visualize said deviation using the at least one luminous element.
