Abstract

A drill bit is disclosed that in one configuration may include at least one cutter on a face section of the bit and at least one opening proximate the at least one cutter configured to discharge fluid under pressure onto the formation to create a fluid cushion between the drill bit and the formation during a drilling operation. An actuation device associated with the drill bit may be utilized to provide fluid under pressure to the at least one opening.
