ABSTRACT:
A method of producing a cutting insert which includes the steps of: providing a generally homogeneous powder blend of powder components; forming the powder blend into a green body wherein the green body includes a rake face and a flank face with a cutting edge at the juncture of the rake face and the flank face; honing the cutting edge of the green body; and consolidating the green body with the honed cutting edge so as to form a consolidated body with a honed cutting edge.
