A milling cutter includes a generally cylindrical body whose outer periphery is formed with angularly spaced pockets capable of accepting indexable cutting inserts of various cutting geometrical shapes, such as inserts having octagonal, square or round cutting geometry's and a different seating geometry, such as a generally round seating geometry. This is accomplished by each insert including a generally frustconical transition face extending between the clearance or faceted faces and the rear face of the insert. This transition face provides a transition area between the various cutting geometry's and the generally round seating geometry.
