Abstract: A tool holder for small hand tools such as screw driver sets, drill sets, etc., which tool holder has external threads near one end which accommodate a compression sleeve which fits over and compresses a tool holding collet/chuck. Within the tool holder is a female hex shaped receptacle which is sized to accommodate a male hex shaft of the collet/chuck. The hex shaped receptacle in the tool holder and the hex shafts of the collet/chuck's act to prevent the collet/chuck's from turning when the tool is subjected to high levels of torque and also allow collet/chuck to be easily interchanged so that a single tool holder can be used to accommodate tools with a variety of shaft cross-sectional shapes such as round, square, hexagonal, etc.
