A hand-held drive-in tool (10) has a trigger switch (19) for triggering a drive-in process by drive unit (30) that drives a drive-in ram (13), a press-on feeler (18) which is arranged so as to be displaceable at a muzzle (16), which can detect that the drive-in tool pressed against a workpiece, and which prevents the actuation of a drive-in process in its initial position (41) and enables actuation of its drive-in process in its switching position (43), a component feeler (17) displaceably arranged at the muzzle (16) and capable of being actuated independently from the press-on feeler (18) and preventing actuation of a drive-in process in its initial position (42) and enabling the actuation of the drive-in process in its switching position (44), the component feeler (17) detecting fitting of an auxiliary constructional component (110) to the muzzle (16), with a drive-in process being initiated by the trigger switch (19) only when the component feeler (17) and the press-on feeler (18) are both in their respective switching positions (43, 44).
