Abstract
A milling insert includes a first axial face, a second axial face, a first radial face, a second radial face parallel with the first radial face, a cutting face, and a generally V-shaped seating face formed with a first seating surface and a second seating surface. The first axial face defines a secondary clearance surface that is at least partially axially recessed from the first axial face and oblique to the first radial face. The first seating surface and the second seating surface are formed at an angle substantially equal to a radial rake angle when the cutting insert is mounted in the insert seat of the milling cutter. As a result, the seating face produces at least one seating surface that is substantially perpendicular to the tangential cutting force, F, thereby reducing movement of the insert when tangentially mounted in the insert seat of the milling cutter.
