The collet holder (300) comprises an inner cone (310), a flat surface (311), and an outer thread (230) for a tensioning nut (401), wherein the tool adapter (500 - 504) comprises an outer cone (320) which complements the inner cone (310), and the collet holder (300) has securing means, which are independent of the outer thread (230) and the tensioning nut (401), for the tool adapter (500 - 504). The securing means comprise one or more radially or diagonally arranged inner threads (315) and a tensioning pin (210) in each inner thread (315), and one or more recesses (317) which interact with the tensioning pin(s) (210) are provided in the tool adapter (500 - 504).
