Abstract

L'invention concerne des ensembles comprenant un foret conçu pour forer un trou et une vis à visser dans le trou foré ou dans une cheville introduite dans ledit trou foré. La vis présente une tête de vis avec au moins un creux. Le foret comporte une mèche avec au moins une saillie, qui est en mesure de s'engager dans le creux de la tête de vis et d'exercer un couple orienté dans le sens longitudinal de la vis pour visser la vis dans le trou foré ou dans la cheville introduite dans ce trou foré. Selon cette invention, le foret sert à forer un trou tout comme à visser la vis. La saillie peut notamment être conçue de manière spatialement complémentaire par rapport au creux de la tête de vis.
