Abstract
An earth-boring tool may comprise a body having at least one blade, and at least one cutting element recess may be formed in a surface of the at least one blade. At least one cutting element may be affixed within the at least one cutting element recess. The at least one cutting element may comprise a substantially cylindrical lateral side surface configured to allow the at least one cutting element to rotate about a longitudinal axis within the at least one cutting element recess when the at least one cutting element is partially inserted into the at least one cutting element recess. The at least one cutting element may also comprise a back face comprising alignment features configured to abut complementary alignment features disposed on a back surface of the at least one cutting element recess. Methods of forming earth-boring tool bodies.
