Abstract: A tool holder for tapping spindles includes a coaxial body (5) composed of an upper hollow half-pin (6) and a lower hollow half-pin (9) which engage mutually and coaxially through a conic semielastic coupling (190) associated with a sequential threaded coupling (11). One (6) of the hollow half-pins includes a continuous conical part (19) capable of sliding in the axial direction, under the action produced by the threaded coupling (11) of the discontinuous conic part (17) of the other hollow half-pin (9). The discontinuous conic part deforms elastically, squeezing on a stem (13) of the tool to be tapped, tying the same.
