  • Patent number: 5595294
    Abstract: The present invention provides a modular bit holder which stores and displays a single bit, and can be linked with other such bit holders to form a variable set. A bit is inserted in one end of the holder and is held in place by a flange. To remove the bit, a second bit is forced into the holder, displacing the first bit to a holding position from which it can be removed. Each holder has means along either side of it to removably attach it in side-by-side fashion to another similar holder.
