摘要：
An earth-boring rotary tool includes a tool body, at least one fixed blade associated with the tool body and configured to carry a fixed cutting element, and at least one leg configured to carry a rolling cutter. The tool body has a slot extending longitudinally generally parallel to a longitudinal axis defining an axial center of the tool body. The slot is at least partially defined by a first sidewall, a second sidewall opposing the first sidewall, a third sidewall extending between the first sidewall and the second sidewall, and an axial end wall of the tool body. A portion of the leg is disposed within the slot of the tool body and abuts the first sidewall of the tool body. A wedge is disposed within the slot and pins the leg to the tool body within the slot.
