Cutting inserts for earth-boring bits

An earth-boring bit comprising:

• an earth-boring bit body;
• and
• at least one cutting insert attached to the earth-boring bit body, the cutting insert comprising a cemented carbide material;
• wherein the cemented carbide material comprises:
• a plurality of tungsten carbide grains;
• a plurality of cubic carbide grains comprising at least one of titanium carbide, vanadium carbide, zirconium carbide, hafnium carbide, niobium carbide, tantalum carbide, and solid solutions thereof;
• and
• a binder comprising at least one of cobalt, a cobalt alloy, nickel, a nickel alloy, iron, and an iron alloy.

A cutting insert for an earth-boring bit, the cutting insert including

• a hybrid cemented carbide material comprising:
• a plurality of first cemented carbide regions comprising tungsten carbide grains in a first region binder comprising cobalt;
• wherein the plurality of first cemented carbide regions comprise a dispersed phase;
• and
• a second continuous cemented carbide region comprising second cemented carbide grains in a second region binder;
• wherein the second cemented carbide grains comprise tungsten carbide and at least one of titanium carbide, vanadium carbide, zirconium carbide, hafnium carbide, niobium carbide, tantalum carbide, and solid solutions thereof;
• and
• wherein the second region binder comprises at least one of cobalt, a cobalt alloy, nickel, a nickel alloy, iron, and an iron alloy;
• and
• wherein the plurality of first cemented carbide regions are dispersed in the second continuous cemented carbide region.
