Abstract: The screwdriving power tool includes a hollow spindle (8) rotatably supported in the tool housing (4) and driven by a motor (26), a clutch (30) that rotatably connects and disconnects the hollow spindle (8) with and from the motor (26), respectively, in engagement and disengagement positions of the clutch (30), a screwing-in spindle (6) connected with a chuck (10) for a working tool (12) and connected with the hollow spindle (8) for a joint rotation therewith and for an axial displacement relative thereto, and a percussion mechanism (14) for applying a pulsed axial force to the screwing-in spindle (6), with the clutch (30) being brought into its engagement position by the screwing-in spindle (6) by being displaced against a biasing force of the clutch springs (40, 44), and being locked in its engagement position.

Abstract: A depth stop for a hand-held screw driving tool including a housing, a drive located in the housing for rotating a spindle about a spindle axis, and a chuck for receiving a working tool, connected with the housing and projecting from the housing in an axial direction defined by the spindle axis with the depth stop (3; 10; 16; 22) including a sleeve-shaped element for surrounding the chuck, connectable with the tool housing (2) and having at lease one axially extending opening formed in a wall of the sleeve-shaped element and piercing the wall through an entire wall thickness, and with the opening having, at its end remote from the housing (2) an entrance region (7; 21; 25) open in the axial direction.

Abstract: A rotary tool for imparting rotation to a drill or an attachment element (2), and including a rotation-imparting element (14), and apparatus (6) for storing a cooling medium, and a conduit (7) for delivering the cooling medium to an operational side end region of the drill or of the attachment element (2).
