In a cutting tool rotatable about a tool axis, a reversible cutting insert is removably secured in a tool body. The cutting insert has opposing top and bottom end surfaces interconnected by a peripheral surface, and a median plane located therebetween. The peripheral surface includes four side surfaces alternating with four corner surfaces, the side and corner surfaces intersecting the top surface to form top major cutting edges and top corner cutting edges, respectively. Each side surface has a median surface and a top major relief surface. Each top major relief surface forms an acute internal top major relief angle with the median plane, and the median plane intersects the four median surfaces to define an imaginary median square. In a top end view of the cutting insert, the four top major cutting edges define an imaginary top major square rotationally offset from the imaginary median square.

A front and back chamfering rotary milling cutter includes a cutter body including an insert pocket and a star-shaped indexable cutting insert releasably retained in the pocket. The cutting insert has star-shaped upper and lower surfaces connected by a peripheral surface intersecting each of the upper and lower surfaces. The cutting insert includes a plurality of circumferentially alternating inner and outer corner portions. A cutting portion is defined by each outer corner portion together with an adjacent first inner corner portion rotationally forward thereof and an adjacent second inner corner portion located rotationally rearward thereof. Each cutting portion includes a front chamfering cutting edge extending from the outer corner portion to the first inner corner portion and a back chamfering cutting edge extending from the outer corner portion to the second inner corner portion.

A cutting insert having two end surfaces and a peripheral surface, the end surfaces located on opposite sides of a mid-plane, each end surface having three primary apexes and three secondary apexes. Six cutting portions are formed along the intersection of the peripheral surface and the end surfaces. Each cutting portion has a first cutting edge and a second cutting edge extending transversely thereto. A ramping cutting edge extends between the second cutting edge of each cutting portion and the first cutting edge of an adjacent cutting portion. The peripheral surface has a clearance surface extending from each of the second cutting edges towards the mid-plane. The abutment planes of the insert are parallel to the mid-plane. Each of the first cutting edges lies between an adjacent abutment plane and adjacent primary apex.

A cutting insert has a trigonal shape. The cutting insert has a peripheral surface that extends between two opposing identical end surfaces. A median plane (M) bisects the cutting insert between the end surfaces. A through bore extends between the end surfaces. A cutting edge, formed at the intersection of each end surface with the peripheral surface, is divided into three identical cutting sections. Each cutting section is located between two vertexes of the trigonal shape. Each cutting section has a convex primary cutting edge and a concave secondary cutting edge that merge together. An insert tangential abutment surface is located between the cutting edge and the through bore. A primary relief surface forms an insert internal obtuse angle with a first reference plane (P). A secondary relief surface forms an insert internal acute angle with a second reference plane (P).
