during a drilling operation so as to stabilize an under gauge drill bit used in association with the stabilizing system the body member further comprises at least one fixed stabilizing surface positioned in an axially spaced relationship to the at least one moveable stabilizing member the body member further comprises a gauge cutter positioned above the moveable stabilizing member and below the fixed stabilizing surface to expand the pilot hole to the final gauge application_number US 16475505 A description referring to the figures of the drawings the embodiment comprises an improved stabilizer and drill bit generally indicated by the numeral 100 the invention in one aspect is generally directed to a drill bit stabilizer having a main body of generally cylindrical configuration and a pin end opposed to a lower drilling end the system is attachable to or includes a drill bit for making a borehole when rotation occurs a throat is formed longitudinally through the main body of the stabilizer for passage of drilling fluid from a drill string through the body and through nozzles of the bit the drilling fluid exits the bit and returns up the borehole annulus a plurality of circumferentially arranged wedge shaped pockets or recesses are formed about the main body from the outer surface of the main body inward to slideably receive corresponding wedge shaped stabilizing members means are provided by which the stabilizing members are spring actuated the stabilizing members are each therefore reciprocatingly received in a slideable manner as they are spring actuated within each respective pocket each of.
