A tool holder comprising:

• a) an elongate barrel with external threads near a first end thereof;
• b) a compression sleeve with internal threads which mate with said external threads of said barrel, said compression sleeve being open at both ends and having an internal diameter tapering inward near an open end distal from said internal threads;
• c) a multi-sided receiver rigidly positioned within the interior of said barrel proximate said first end;
• and
• d) a plurality of interchangeable tool holding collet/chucks, each with a multi-sided shaft at a first end, each said shaft being sized to removably fit within said multi-sided receiver, each said collet/chuck including a terminal portion with a tool receiving opening sized to receive the shaft of a tool to be held, said tool receiving opening being formed by at least one slot extending across said terminal portion, said terminal portion tapering outward in external diameter from an end distal to said shaft back toward said shaft, wherein each of said plurality of collet/chucks has a different slot orientation and/or tool receiving opening size or shape such that tools with a plurality of different shaft sizes and shapes can be used with the tool holder.
