Abstract
An edge rounded cutting tool insert which shows less flank wear in the nose area and improved toughness behavior on the main cutting edge. The improved toughness and decreased flank wear is achieved by decreasing the W/H ratio and increasing H from the nose area to the middle of the main cutting edge wherein W is the width of edge rounding of the cutting edge along the rake face and H is the width of edge rounding of the cutting edge along the clearance face.
