A screwdriver having a plurality of bits. There is housing having a hollow interior to receive the bits. The housing has a handle and an open end, remote from the handle. There is an internal column that is attached to the housing. The internal column has a recessed end to receive a bit and prevents rotation of the bit relative to the housing. There are openings around the housing extending longitudinally of the housing. Each bit is operated by an actuator extending through an opening in the housing. There is a leaf spring attached to the inner end of the actuator that receives a bit. The bit may be moved from a position of storage within the handle by pressing a pre-selected actuator, moving the bit attachment out of the open end of the housing, holding the actuator down and retracting the bit to engage the recess of the column. The guidance system is simpler than the prior art. The handle is smaller than the prior art systems. The mode of operation is simple.
