Zusammenfassung:PURPOSE: To protect a taper part in a tool holder from cut metallic chips scattering around by introducing the tool holder in a magazine position into a hollow space forming a closed cover for the taper part. CONSTITUTION: A machine tool is provided with a rotating spindle 11 and a plurality of tool holders 14. Each of the tool holders 14 is provided with a taper part 13. While one of the tool holders 14, each of which can be inserted independently into a machining position of the spindle 11 by means of a grip arm 20 from a magazine position remote from the spindle 11 as a starting position, other tool holders 14 remain in the magazine position. The tool holder 14 remaining in the magazine position is introduced into a hollow space 40 forming a closed cover for the taper part 13. Consequently the taper part 13 of the tool holder 14 in the magazine position can be protected from cut metallic chips scattering around.
