Abstract

Methods of drilling subterranean formations include coupling at least one bearing block having an initial thickness to a drill bit, engaging a formation with the drill bit within an initial depth of cut range, and reducing the initial thickness of the bearing block by contacting the formation to cause the initial depth of cut range to be at least partially increased. Methods of forming drill bits for drilling subterranean formations include forming at least one rubbing surface of at least one bearing block from at least one material exhibiting a reduced coefficient of friction and coupling the at least one bearing block to the drill bit. Drill bit assemblies include at least one bearing block having a distal portion configured to provide an initial depth of cut range and a base portion configured to provide an increased depth of cut range greater than the initial depth of cut range.
