A borehole tool, comprises: a tool body; a series of arms connected to the tool body and moveable radially relative thereto; and a series of pads mounted on the arms so as to be pivotable about a radial axis relative to the tool body. By allowing pivoting of the pads about a radial axis, elongate pads can be arranged to provide different circumferential coverage according to the orientation with respect to the longitudinal axis of the borehole.

La présente invention a trait à un outil de trou de forage comportant : un corps d'outil, une série de bras reliés au corps d'outil et radialement mobile par rapport à celui-ci, et une série de pastilles montées sur les bras apte à être en pivotement autour d'un axe radial par rapport au corps d'outil. Grâce au pivotement des tampons autour de l'axe radial, des pastilles de forme allongée peuvent être agencées pour assurer une couverture circonférentielle différente selon l'orientation par rapport à l'axe longitudinal du trou de forage.
