ABSTRACT:
A multi-bit screwdriver comprises a handle with a bit selector cup rotatably mounted at its end. A plurality of bits are provided in a circular pattern within a handle magazine. A chuck is provided at the handle end for receiving a bit end and securing it against rotation. The cup has a continuous side wall with an interior surface spaced radially outwardly of the radial location of the bits. An elongate slot is provided in the cup end extending from the central portion of the cup radially outwardly to the radial location of the bits in the handle. The cup is rotatable to permit selection of a desired bit and withdraw it from the magazine. The bit end is retained in the cup for lateral transfer along the slot into registration with the chuck.
