摘要：
A downhole cutting tool for drilling a borehole in an earthen formation may include a tool body having a tool axis and a direction of rotation about the tool axis; at least two blades attached to the tool body, the at least two blades having a leading face facing the direction of rotation of the tool body about the tool axis, a trailing face facing away from the direction of rotation of the tool body about the tool axis, and a formation facing surface extending between the leading face and the trailing face; and a plurality of cutting elements disposed on the at least two blades, each cutting element having a radial distance from the tool axis; wherein at least one blade, at its formation facing surface, comprises, between two radially adjacent cutting elements on the at least one blade, a raised depth of cut feature for each cutting element on the other of the at least two blades that are at radial distances from the tool axis intermediate the radial distances from the tool axis of the radially adjacent cutting elements on the at least one blade.
