Abstract: The present invention discloses a new surface geometry of a polycrystalline diamond (PCD) cutter whereby large chips are prevented from forming in front of the cutter. The surface geometry includes recess(es) and/or raised region(s) that can act as chip breakers and also increase turbulence in the flow across the face of the cutter and thus increase the Heat transfer coefficient and reduce drag. PCD surface's geometric configuration is formed in the high temperature/high heat (HT/HP) process and is therefore integral with the cutter. This invention thus provides a polycrystalline cutter with improved cutting capability by preventing chip build up and enhanced heat transfer resulting in a cooler cutting edge temperature.
