A surgical tool holder 12 and tool system 10 is provided. The surgical tool holder ( 12 ) is adapted to connect to a tool support ( 14 ) having an interface receiver ( 36 ). The tool support provides a mount for a surgical tool head. The tool holder ( 12 ) includes a center rod ( 20 ), a tool interface ( 28 ) and a quick connect mechanism ( 50 ). The center rod ( 20 ) has a first shank end ( 24 ) and a second tool end ( 26 ). The tool interface ( 28 ) is disposed on the tool end ( 26 ) of the center rod ( 20 ). The tool interface ( 28 ) has at least one transversely extending portion ( 44, 44 a), extending radially outward, beyond the diameter of the center rod ( 20 ) at the tool end ( 26 ). The interface ( 28 ) is adapted to engage with the interface receiver ( 36 ). The quick connect mechanism ( 50 ) is disposed on the center rod ( 20 ) to move in a rotationally-constrained manner thereon proximate the tool interface ( 28 ). The mechanism ( 50 ) includes protrusions ( 66 ) biased to bear against and engage the tool support ( 14 ) when the tool support is engaged with the tool interface ( 28 ). This securely holds the tool support ( 14 ) and prevents its relative rotation with respect to the tool holder ( 12 ).
