Abstract
Methods of operating earth-boring tools may involve extending a selectively actuatable cutting element outward from a face of the earth-boring tool. A portion of an underlying earth formation may be crushed by a crushing cutting action utilizing the selectively actuatable cutting element in response to extension of the cutting element. The selectively actuatable cutting element may subsequently be retracted. Earth-boring tools may include a selectively actuatable cutting element mounted to a blade, the selectively actuatable cutting element configured to move between a retracted state in which the selectively actuatable cutting element does not engage with an underlying earth formation and an extended state in which the selectively actuatable cutting element engages with the underlying earth formation. The selectively actuatable cutting element may be configured to perform a gouging or crushing cutting action at least upon initial positioning into the extended state.
