Abstract

L'invention concerne un outil de fond de puits qui comprend un corps pourvu d'une fente en son sein, une lame de coupe montée dans le corps et susceptible d'être déployée et rétractée par la fente de manière que le diamètre extérieur de l'outil puisse être sélectivement accru, un élément d'actionnement destiné à entraîner la lame de coupe entre les positions déployée et rétractée et un moyen de montage reliant la lame à l'élément d'actionnement. Ledit corps présente une surface conique le long de laquelle la lame suit sa course de façon que, au fur et à mesure de la course de la lame le long de la surface conique, la lame ait un déplacement radial vers l'extérieur par rapport au corps et au moyen de montage tout en restant en contact avec la surface conique.
