A tool for housing and supplying bits by which they can be driven such as a screw driver or drill has a housing with an elongate tube extending through the housing along the axis to a forward presentation end of the tube at which the bits are presented for use. The housing has a rotatable storage holder mounted in the housing for holding and storing a plurality of tool bits and arranged by manual engagement with an exposed side portion to rotate about a second axis parallel to the tube. The rotatable holder has a plurality of receptacles each for receiving a respective one of the tool bits arranged parallel to the second axis and in angularly spaced relation around the second axis. The rotatable holder is manually rotated to cause each receptacle in turn to move to a position aligned with the tube where a plunger mounted within the tube is moved forward and rearward therein from a retracted position, in which a forward end of the plunger is retracted rearwardly of the holder, to a forward position adjacent the forward presentation end. The plunger has a flat magnetic bit carrying face at the forward end. The holder is rotatable in the housing when the plunger is moved to the retracted position to move the bit off the flat face. The housing includes a drive member which may be just a manual rotation of the housing for causing rotation of the tube and thus the bit at the forward presentation end.
