15. The protective leaching mask assembly of claim 1 , wherein the superabrasive table of the superabrasive element is affixed to a substrate at an interface, the substrate including a substrate side surface forming a portion of the side surface of the super abrasive element; and

wherein the protective mask includes a binding member loading portion, the binding member loading portion including a substantially constant diameter portion located between a top edge of the protective mask and a location between the substrate side surface and the interface.

16. The protective leaching mask assembly of claim 1 , wherein:

the superabrasive table of the superabrasive element is affixed to a substrate at an interface, the substrate including a substrate side surface; and

the superabrasive table includes a superabrasive face, a superabrasive side surface, and a chamfer formed between the superabrasive face and the superabrasive side surface, wherein the side surface of the superabrasive element includes the substrate side surface and the superabrasive side surface.

17. The protective leaching mask assembly of claim 16 , wherein the protective mask covers at least a portion of the superabrasive element including the substrate side surface and the superabrasive side surface between the chamfer and the interface.

18. The protective leaching mask assembly of claim 16 , wherein the protective mask covers at least a portion of the superabrasive side surface.

19. The protective leaching mask assembly of claim 1 , wherein the binding member includes a ring-like binding member having:

an inner surface defining an opening through which at least a portion of the protective mask extends and in contact with the at least a portion of the outer surface of the at least one sidewall;

an outer surface spaced from the inner surface of the binding member;

an outer diameter of between about one-half inch and about three inches; and

a thickness of between about one-fourth inch and about two inches as measured from the inner surface of the binding member to the outer surface of the binding member.

20. A protective leaching mask assembly, comprising:

a superabrasive element including a rear face, a side surface, and a superabrasive table having a chamfer; and
