Abstract
A cutting insert for the metalworking industry is disclosed having a cutting edge, a land area, a descending wall and a sloping wall that joins a planar floor in the central portion of the insert. The cutting insert is polygonal when viewed in plan and has rounded corners joining the sides of the insert. The insert has at least two angularly related cutting edges defining a plane. The perpendicular distance between the plane defined by the cutting edges and the point where the descending wall joins the sloping floor is at a minimum in the corner areas and at a maximum intermediate the adjacent corners of the insert.
