ABSTRACT:
A multiple bit screwdriver employs a breach loading magazine to store a plurality of bits. The magazine is enclosed inside the hollow handle of the screwdriver and is extracted along the axis of the screwdriver when the end-cap of the handle is pulled. The bits are stored in the magazine and are located about the circumference of the magazine tube that reciprocates relative to the screwdriver. When the magazine is fully extracted, the bits are easily viewed and may be individually removed from or replaced in the clips applying a simple radial force.
