Abstract

L'invention concerne une machine-outil portative (100) comprenant une unité d'entraînement destinée à entraîner en rotation une broche de sortie, ladite unité d'entraînement pouvant passer d'un premier sens de rotation à un second sens de rotation et inversement, afin de permettre un entraînement de la broche de sortie dans le premier ou dans le second sens de rotation. Selon l'invention, une interface de communication (1050) permet la communication avec une unité de guidage d'utilisateur (115) pouvant être actionnée par un utilisateur, ladite interface de communication (1050) étant conçue pour recevoir, en provenance de l'unité de guidage d'utilisateur (115), des consignes de changement de sens de rotation afin de faire passer l'unité d'entraînement du premier au second sens de rotation ou inversement selon l'application.
