The tool body has a longitudinal axis and at least one reamer blade configured to be outwardly extendable for use in an expandable reamer and attachable on a fixed-blade reamer. The at least one reamer blade is attached to the tool body in an immovable manner relative to the tool body during use of the earth-boring tool in the formation of a subterranean wellbore.
