Zusammenfassung:	A drill is provided with a chuck that is capable of being tightened or loosened by operation of the drill. The chuck includes a shift mechanism that interacts with the multi-speed transmission of the drill to ensure that the transmission is shifted into a desired gear ratio whenever the chuck is shifted from a drill mode to a chuck mode. L'invention concerne une perceuse pourvue d'un mandrin pouvant être serré ou desserré par le fonctionnement de la perceuse. Le mandrin comprend un mécanisme de changement de vitesse en interaction avec la transmission multi-vitesses de la perceuse pour assurer que la transmission est changée en un rapport de transmission désiré dès que le mandrin passe d'un mode perçage à un mode desserrage de mandrin.
