Patent ID: 8096372

Claim:
A cutter for an earth boring fixed cutter drill bit comprising: a base portion with a longitudinal axis that extends through a center of said base portion; and a planar cutting face disposed on an end opposite said base portion and arranged generally perpendicular to said longitudinal axis, said planar cutting face centered with respect to said base portion such that said longitudinal axis extends through a center of said planar cutting face, wherein said base portion and said planar cutting face have a periphery edge comprising: a first arcuate edge segment and a second arcuate edge segment spaced apart and arranged opposite each other with linear segments disposed there between joining said first arcuate segment and said second arcuate segment, said base portion and planar cutting face spanning a maximum edge-to-edge dimension L along a first direction corresponding with a major axis of said base portion and planar cutting face which intersects said first and second arcuate segments, and spanning a maximum edge-to-edge dimension W along a second direction perpendicular to said first direction, said base portion and planar cutting face having a minor axis aligned with said second direction, wherein said first arcuate segment comprises a radius of curvature that is greater than a radius of curvature along said second arcuate segment.
