Summary:A steerable downhole tool may alter a direction of travel of a drilling operation while drilling into the earth. The tool may accomplish this by extending a rod from openings disposed in a side of the tool. The rod may slide within a cavity passing from one of the openings to another. The rod may degrade material from an internal surface of a borehole in which the tool is traveling, by engaging the surface with cutter elements exposed on opposing tips of the rod. The tool may also push off of the borehole wall opposite from the area of degradation.
