Zusammenfassung:	An apparatus for changing a drilling tool (215) for a drilling machine (100) where the drilling machine (100) comprises a drill tower (110) supporting a string of drill pipe (150). The apparatus has a drilling tool changer assembly (190) moveable between a storage position and an exchange position. The drilling tool changer assembly (190) supports a rotatable carousel assembly (230). The rotatable carousel assembly (230) can be removed from the drilling tool changer assembly (190) and replaced on the drilling tool changer assembly (190) in the same angular position with respect to the drill pipe (150) as when removed. The rotatable carousel assembly (230) has a plurality of bit adaptors (235) for holding drilling tools (215) and is rotatable to bring a selected drilling tool (215) into coaxial alignment with the drill pipe (150) when the drilling tool changer assembly (190) is moved into the exchange position.
