The intersection of the top surface, end wall and sides forming a cutting edge. The top surface includes a cutting land of a generally concave shape about an axis longitudinally extending between the sides and sloping downwardly and inwardly from the cutting edge, a chipgroove area adjoining the cutting land and extending inwardly therefrom and disposed at a lower elevation than the cutting edge, and an upsloping chipbreaker portion adjoining the chipgroove area and the cutting land and leading to a plateau disposed at a higher elevation than the cutting edge and chipgroove area. The chipbreaker portion is configured symmetrically about the axis and includes a forwardly extending fingerlike projection on either side of and continuous with a rearwardly recessed region bisected by the axis.
