Abstract

See full text

An earth-boring tool includes a tool body configured to rotate in a wellbore and carrying at least one extendable element. The at least one extendable element is configured to move between a retracted position and an extended position projecting radially beyond the tool body. The at least one extendable element has a mating surface. The earth-boring tool includes a support structure located in the tool body and having a support surface that is located and configured to face the mating surface of the at least one extendable element when the at least one extendable element is in the extended position. The support surface of the support structure is configured to bear at least a portion of the tangential forces acting on the extendable element during rotation of the earth-boring tool in the wellbore when the at least one extendable element is in the extended position.
