1. A drill bit, comprising:
a bit body defining a rotational axis;
a plurality of cutters secured to the bit body, including a gauge cutter disposed on a gauge section and defining a gauge diameter of the drill bit; and
a reciprocating gauge assembly comprising a cavity defined in the bit body, a piston reciprocably disposed in the cavity, a wear element on an outwardly facing end of the piston, a piston retainer for moveably retaining the piston in the cavity comprising a retention hole defined transversely through the piston and a fastener extending through the retention hole and into the bit body to retain the piston within the cavity, wherein the retention hole in the piston is wider than the fastener in an axial direction of the piston to allow reciprocation of the piston within the cavity; and
a spring biasing the piston outwardly to a neutral position of the wear element under gauge.
