Abstract
For drill bit cutter indexing, a housing is disposed in a drill bit. An indexing cog is in physical communication with a cutter and interlocks with the housing in a first index position of a plurality of index positions in response to a first compressive load applied to the cutter. A motivator disengages the indexing cog from the housing and positions the indexing cog to interlock with the housing at an initial second index position in response to a removal of the compressive load from the cutter.
