Methods of attaching a polycrystalline diamond compact (PDC) element to a substrate include maintaining a gap between the PDC element and an adjacent substrate, and at least substantially filling the gap with a deposition process. Methods of forming a cutting element for an earth-boring tool include forming a PDC element by pressing diamond crystals together, forming a substrate including a particulate carbide material and a matrix material, leaving a gap between at least portions of the PDC element and the substrate, masking surfaces of the PDC element and of the substrate that do not face the gap, and forming an adhesion material on surfaces of the PDC element and of the substrate that face the gap. Cutting elements for earth-boring tools include a PDC element attached to a substrate with at least one of diamond, diamond-like carbon, a carbide material, a nitride material, and a cubic boron nitride material.

A rotary tool for drilling subterranean material is disclosed. The rotary tool includes a tool body having a distal crown end comprising a circumferential series of raised cutting blades with recessed junk slots therebetween. Cutting elements are located proximate a leading peripheral edge of the raised cutting blades and cutting control structures are located interiorly of the cutting elements at a leading surface of an adjacent junk slot. Cutting control structures are releasably secured to the tool body in the adjacent junk slot whereby a used rotary tool is refurbishable by removing worn cutting control structures without degradation to the tool body and replacing the worn cutting control structures by installing new cutting control structures in the worn cutting control structures' locations.

Earth-boring tools comprise a body comprising a plurality of radially extending blades. At least one blade of the plurality of radially extending blades comprises a blade support segment integral with the body. A blade frame segment is attached to a rotationally leading portion of the blade support segment. A plurality of cutting elements is attached to the blade frame segment. Methods of forming an earth-boring tool comprise forming a body including a blade support segment of at least one blade. At least one blade frame segment is attached to a rotationally leading portion the support segment of the at least one blade. A plurality of cutting elements is secured to the at least one blade segment.

Methods of forming earth-boring tools and related structures

An earth-boring tool includes a formation-engaging structure with a formation-engaging surface at a distal end and a side surface between a proximal end and the distal end along a central axis of the formation-engaging structure. A generally linear recess may be formed in the side surface along an axis oriented at a non-parallel angle relative to the central axis of the formation-engaging structure. A generally helical recess may be formed in the side surface, and the generally helical recess may intersect the generally linear recess. Earth-boring tools may include such formation-engaging structures. Methods may be used to form such formation-engaging structures.
