Retainer (11) comprises first and second parallel spaced cavities (33, 35) in base (25) for receiving either a screwdriver bit (13, 15) or a chuck key handle (21). A third cavity (49), which is disposed in base (25) perpendicular to and intersecting with cavities (33, 35), is for receiving chuck key spindle (23). A fourth cavity (81) may also be provided intermediate the first and second cavities for receiving another screwdriver bit (79). Retainer (11) is preferably embodied in a power screwdriver/drill (12), is used to store only screwdriver bits (13, 15, 79) when the power tool is equipped with a keyless chuck and is used to store a screwdriver bit (79) and a chuck key (17) when the tool (12) is equipped with a keyed chuck (29).
