A drill bit for removing subterranean formation material in a borehole comprises a bit body comprising a longitudinal axis, a plurality of blades extending radially outward from the longitudinal axis along a face region of the bit body and extending axially along a gauge region of the bit body, and an insert coupled to at least one blade in the gauge region. The insert comprises an elongated body having an upper surface, a lower surface, and a longitudinal axis extending centrally therethrough and intersecting the upper and lower surfaces. The upper surface comprises a bearing surface for supporting for the drill bit and providing a surface on which the subterranean formation being drilled rubs against the insert without exceeding the compressive strength of the selected formation. The insert is coupled to the blade such that the upper surface thereof extends radially beyond an outer surface of the blade and the lower surface thereof extends radially below the outer surface of the blade.

Earth-boring tools having a gauge insert configured for reduced bit walk and method of drilling with same

Earth-boring tools include a body, at least one first blade extending outward from the body, and at least one second blade extending outward from the body. The at least one first blade includes an upper surface, a first gage region having a first longitudinal length, and a recess extending at least partially into the at least one first blade from the upper surface. The at least one second blade includes a second gage region having a second, greater longitudinal length. Additional earth-boring tools include first blades having first gage regions of a first longitudinal length and second blades having second gage regions of a second, greater longitudinal length. An upper external surface is tapered radially outward in a longitudinally upward direction relative to a central axis of the earth-boring tool. Methods including forming such first and second blades and removing material from the first blades to form recesses.
