Earth-boring tools include one or more cutting elements having at least one grading feature positioned a known distance from an initial working surface of the cutting element. Methods of grading cutting element loss on earth-boring tools include comparing locations of wear surfaces on cutting elements to locations of one or more grading features in or on the cutting elements. In some embodiments, a cutting element may comprise an insert having a generally cylindrical body, a substantially planar cutting face surface, a substantially arcuate side surface, and at least one grading feature. In additional embodiments, a cutting element may comprise a tooth having one or more grading features.
An earth-boring tool, comprising at least one cutting element having at least one grading feature positioned a known distance from an initial working surface of the at least one cutting element.
A method of forming a cutting element for an earth-boring tool, comprising:
A method of grading an earth-boring tool, comprising correlating relative locations of at least a portion of a wear surface and at least one grading feature in or on at least one cutting element of the earth-boring tool to an amount of cutting element loss.
A cutting insert for an earth-boring tool, comprising:
A cone for an earth-boring bit, comprising:
