A hand tool device (1), for a partially rotationally driven drill tool (2), including an electronic depth stop (3) with a sensor (4) for non-contacting gauging of a distance and a calculator component (5) for calculating the depth (T) of a drill bit tip (8) relative to a reference surface (10), and signaling when a measured value attains a set value (S). The set value (S) can be transmitted into a set value memory (6) using a single manually operated transfer accept actuation.
