The rotating head selectable screwdriver allows a user to insert four 1/4" hex bits of their choosing into each slot. The device can then be placed into any 1/4" hex head slot on a screwdriver or drill. The user can then use the screwdrivers and quickly move between them, using just one hand, depending on the screw, bolt, or other device being installed or removed. A spring pin ensures the selection remains locked in when being used but still easily moved when the user requires a different bit. Perfect for technicians, repairmen, assembly workers, or anyone who uses multiple screwdrivers. The second version was made in black resin.
