Abstract

Cette invention concerne un centreur destiné à être utilisé dans des opérations de fond de trou. Le centreur est constitué d'un corps cylindrique creux ayant une surface externe exposée et fait d'un matériau non métallique, une pluralité de lames non métalliques faisant saillie à partir de la surface externe du corps cylindrique, et une pluralité de boutons d'usure positionnés sur chacune de la pluralité de lames, chacun des boutons d'usure ayant une surface conçue pour réduire la préhension ou le collage et l'usure du corps cylindrique creux, telle qu'une surface ovale lisse.
