In a tool holder assembly for a reciprocating dental tool including a hollow tool holder defining a tool holder chamber therein within which a dental tool may be mounted, a clamping mechanism is provided whereby a plurality of clamping balls are located about the periphery of the tool holder in order to impart a radial force to a tool body positioned within the holder. The tool holder includes a plurality of bores extending to its internal tool holder chamber and a clamping nut having a conically shaped inner surface engages the clamping balls and imparts thereto a radial force so that the balls, which are loosely mounted within the bores, may extend to within the tool holder chamber to clamp a tool therein.
