1. A hand-held power tool, comprising:
a housing, in which at least one drive unit configured to drive a tool holder is arranged, wherein the tool holder is designed to hold an insertable tool;
wherein the housing includes a handle which connects an upper side of the housing and a base region of the housing to one another;
wherein the drive unit can be switched on and off by means of a manual switch arranged on the handle between the upper side and the base region, and
an alignment apparatus having a control unit and having at least one luminous element, said at least one luminous element including a first luminous element arranged on the base region of the housing, wherein the alignment apparatus is designed to determine, in real time, during operation of the hand-held power tool, a current deviation of a machining angle, which is selected via the control unit and which is formed between the insertable tool that is inserted in the tool holder and a workpiece surface that is to be machined by the insertable tool, from an actual inclination angle between the insertable tool that is inserted in the tool holder and the workpiece surface to be machined by the insertable tool, and to visualize said deviation using the first luminous element.
