Abstract
A drill bit can include a bit body having an upper portion, a central bore, and an adjustable inner gauge. The central bore can define a bore surface, and the bit body can include a plurality of fixed cutters formed on the upper portion. The adjustable inner gauge may be movably positioned within the bit body central bore to increase or decrease an exposed area of the bore surface for adjusting stability or steerability of the drill bit while forming the wellbore.
