Abstract
Earth-boring tools include wear-resistant materials disposed in at least one recess formed in an exterior surface of a body thereof. Exposed surfaces of the wear-resistant material are substantially level with exterior surfaces of the body adjacent the wear-resistant material. In some embodiments, recesses may be formed in formation-engaging surfaces of blades of earth-boring rotary tools, adjacent one or more inserts secured to bodies of earth-boring tools, or adjacent one or more cutting elements secured to bodies of earth-boring tools. Methods of forming earth-boring tools include filling one or more recesses formed in an exterior surface of a body with wear-resistant material and causing exposed surfaces of the wear-resistant material to be substantially level with the exterior surface of the body.
