Beschreibung
Zusammenfassung:	Earth-boring tools may include a body and a passively adjustable, aggressiveness-modifying member secured to the body. The passively adjustable, aggressiveness-modifying member may be movable between a first position in which the earth-boring tool exhibits a first aggressiveness and a second position in which the earth-boring tool exhibits a second, different aggressiveness responsive to forces acting on the passively adjustable, aggressiveness-modifying member. L'invention concerne des outils de forage qui peuvent comprendre un corps et un élément de modification d'agressivité réglable de façon passive fixé au corps. L'élément de modification d'agressivité réglable de façon passive peut être mobile entre une première position dans laquelle l'outil de forage présente une première agressivité et une seconde position dans laquelle l'outil de forage présente une seconde agressivité différente réagissant aux forces exercées sur l'élément de modification d'agressivité réglable de façon passive.
