Abstract
A cutting insert that has a flank face and a rake face and a cutting edge at the juncture thereof. The substrate presents a bulk region that contains a metallic binder, as well as one or more of Group IVB, Group VB, and Group VIB metal carbides and/or carbonitrides. The substrate further includes a flank surface region near the flank face of the substrate that has a solid solution metal carbide and/or carbonitride content greater than that of the bulk region. The substrate includes a rake surface region near the rake face of the substrate with a solid solution metal carbide content that is less than that of the flank surface region.
