A cutting tool insert comprising:

• a substantially flat body member having a cutting portion located at a first end and a seat portion located at a second end, said seat portion for seating said cutting tool insert in a tool holder;
• said flat body member having a first face and second face;
• said cutting portion having a first arcuate cutting lobe and second arcuate cutting lobe symmetrically disposed adjacent to a centerline of said body member;
• each of said first cutting lobe and second cutting lobe having a peripheral edge adjacent to each of said first face and second face;
• a first cutting edge disposed on said first cutting lobe and a second cutting edge disposed on said second cutting lobe, said first cutting edge and second cutting edge being substantially disposed at an intersection of said peripheral edge and one of said first face and second face;
• said cutting portion having a void disposed at the centerline of said body member between said first and second cutting lobes, said void comprising a first relief disposed adjacent to said first cutting lobe and a second relief disposed adjacent to said second cutting lobe wherein an entirety of said first cutting edge and an entirety of said second cutting edge are spaced apart from one another on opposite sides of said void by a distance greater than a radius of curvature of said first and second cutting lobes, said void being V-shaped and defined by a pair of diagonal surfaces which extend from one of the first and second cutting lobes to the other and intersect at a centerline of said body member;
• and
• said body member having a hole passing therethrough.
