Patent

CA 2595048

An improved cutter for fixed cutter drill bits includes a base portion with a longitudinal axis that extends through a center of the base portion and a cutting face which is generally centered with the base portion. The cutting face has a periphery edge geometry comprising a first arcuate segment and a second arcuate segment spaced apart and arranged opposite each other with linear edge segments disposed there between forming sides of the cutting face. The cutting face spans a maximum edge-to-edge dimension L in a first direction that corresponds to a major axis of the cutting face. The cutting face spans a maximum edge-to-edge dimension W in a second direction, which is perpendicular to the first direction, and W is less than L.
