Abstract
A disclosed embodiment for a drill bit arm for a rotary subterranean drill bit includes a pocket that extends radially inward from an outer surface of the drill bit arm. The pocket may include a void where work piece material has been removed. The pocket may be next to a leading edge of the drill bit arm and may extend to remove at least a portion of a trailing edge of the drill bit arm. When the drill bit arm includes a lifting surface, the pocket may be next to and follow an upward curvature of the lifting sur face. The pocket may reduce wear and tear on the drill bit arm during operation. The pocket may provide a location for placing a desired piece of equipment, such as an instrumentation element and/or a communication element.
