A cutting insert for use in a peripheral rotary milling cutter having a cylindrical holder and a side cutting edge defined between a cutting rake surface and a side relief flank and a side base edge defined between the side relief flank and a base surface. The side relief flank has first and second component side relief flank surfaces which intersecet at an intersection line, the latter extending along the side relief flank from a first position adjacent a leading end of the insert and located at an intermediate position thereof to a second position intersecting the cutting edge and adjacent a trailing end of the insert. The component flank surfaces are substantially planar and are angularly disposed with respect to one another so that an insert side relief angle (.gamma..sub.A) as defined with respect to the cylindrical holder in the region of the leading end substantially equals an insert side relief angle (.gamma..sub.B) in the region of the trailing end.
For use in a peripheral rotary milling cutter having a cylindrical holder and at least one replaceable, peripherally disposed cutting insert, a cutting insert having a side cutting edge defined between a cutting rake surface and a side relief flank and a side base edge defined between said side relief flank and a base surface, wherein said side relief flank comprises first and second component side relief flank surfaces intersecting at an intersection line extending along the side relief flank from a first position adjacent a leading end of the insert and located at an intermediate postion thereof to a second position intersecting said cutting edge and adjacent a trailing end of the insert, said component flank surfaces being substantially planar and being angularly disposed with respect to one another so that an insert side relief angle as defined with respect to the cylindrical holder in the region of the leading end substantially equals an insert side relief angle in the region of the trailing end.
