ABSTRACT:
A depth stop device (14) for use with a hand-held screw driving tool (2) includes an axial element (32) for driving a screw bit (34) and a sleeve element (20) having a longitudinal bore (30) in which the axial element (32) is at least partially received and an exit opening (36) extending sidewise from the longitudinal bore (30). The exit opening (36) is limited by a deflection surface (40) which is stretched over an intersection plane (SE) and has a geometrical center (M) that forms an origin of a spatial system of coordinates. The intersection plane (SE) forms with a tangential axis (T) of the spatial coordinate system that extends perpendicular to both the longitudinal (L) and radial (R) axis of the coordinate system, an acute angle (α).
