Abstract

A cutting element assembly includes a rotatable cutting element, a sleeve having a cutter receiving aperture extending at least partially through the sleeve and configured to receive at least a portion of the rotatable cutting element within the cutter-receiving aperture, and a retention element rotatably coupling the rotatable cutting element to the sleeve. In some embodiments, the retention element includes a pin extending from a base portion of the sleeve and having at least one resilient portion having at least one protrusion radially extending outward. In additional embodiments, the retention element include a split ring or O-ring disposed within a groove of the rotatable cutting element. Earth-boring tools having rotating cutting elements are also disclosed.
