    摘要: A cutting tool that includes an elongate body that has a forward end and a rearward end. The elongate body has a fluted portion that beginning near and extends in a rearward direction from the forward end. The fluted portion has a flute that defines a cutting edge. The flute presents a concave cutting face wherein the concave cutting face is defined by a first radius. The flute further presents a concave core surface adjacent to the concave cutting face wherein the concave core surface is defined by a second radius. The flute presents a convex heel surface adjacent to the concave core surface wherein the convex heel surface is defined by a fourth radius.

    摘要: A cutting tool that includes an elongate body (22) that has a forward end (26) and a rearward end (24). The elongate body (22) has a fluted portion (30) that beginning near and extends in a rearward direction from the forward end (26). The fluted portion (30) has a flute (36, 38, 40, 42) that defines a cutting edge. The flute presents a concave cutting face (60) wherein the concave cutting face (60) is defined by a first radius (R1). The flute further presents a concave core surface (66) adjacent to the concave cutting face (60) wherein the concave core surface (66) is defined by a second radius (R2). The flute presents a convex heel surface (64) adjacent to the concave core surface (66) wherein the convex heel surface (64) is defined by a fourth radius (R4).
