Drill bit cutter fitted with a threaded member
Abstract:
Methods and systems for maintaining a drill bit includes positioning a cutter within a recess of a drill bit body so that an initial edge is positioned at a first location that is a radially outward location relative to a blade of the drill bit. A threaded member extended through a central bore of the cutter can be rotated to releasably secure the cutter to the drill bit. The subterranean well is drilled with the drill bit. The threaded member can be rotated in a second direction so that the cutter can be rotated relative to the recess and the initial edge of the cutter is positioned at a second location that is rotationally offset from the first location. The threaded member can be rotated to releasably re-securing the cutter to the drill bit and the subterranean well can continue to be drilled with the drill bit.
