Abstract: An earth-boring tool includes a body, at least one blade, and at least one rotatable cutting structure. The blade extends axially from the body and extends radially outward from a center longitudinal axis of the earth-boring tool to less than an outer diameter of the earth-boring tool. The blade defines a first cutting profile. The at least one rotatable cutting structure assembly is coupled to the body and includes a leg extending axially from the body and a rotatable cutting structure rotatably coupled to the leg. The rotatable cutting structure defines a second cutting profile extending to the outer diameter of the earth-boring tool. The first cutting profile overlaps with the second cutting profile in a radial direction in an amount that is less than 20% of the outer diameter of the earth-boring tool. A method of making an earth-boring tool.

Abstract: An earth-boring tool includes a movable component and an additive manufacturing formed flow control device in fluid communication with the movable component and configured to control a flowrate of the hydraulic fluid through the additive manufacturing formed flow control device, wherein the additive manufacturing formed flow control device is configured to control a movement of the movable component via the flowrate of hydraulic fluid through the additive manufacturing formed flow control device. An earth-boring tool includes an additive manufacturing formed flow control device in fluid communication with one or more components of the earth-boring tool and configured to provide a cooling fluid to the one or more components of the earth-boring tool.
