Depth stop device
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).
