Abstract

L'invention concerne un dispositif porte-outil équipé d'un outil travaillant à la torsion. Ledit dispositif comporte un mandrin qui serre un outil tel qu'un foret comportant des ailes opposées d'une dimension et d'une forme telles que les mors du mandrin exercent une pression contre les cotés des ailes rigides, tandis que les trois mors tendent à entrer en contact et à serrer la queue de l'outil de façon que ledit mandrin puisse être serré et desserré à la main. Lorsque les mors sont affouillés de façon que leurs parties de serrage ne se touchent pas lorsqu'ils sont réunis, les ailes peuvent être plus flexibles pour permettre aux trois mors d'entrer en contact avec la queue de l'outil. Application aux perceuses et aux outils travaillant à la torsion utilisés dans ces dernières, tels que des forets hélicoïdaux.
