    摘要： A cutting insert has polygonal first and second end surfaces which are connected by a peripheral side surface, each end surface defining first and second end planes, respectively. The peripheral side surface has first peripheral side portions alternated in the circumferential direction with second peripheral side portions. The first peripheral side portions are inverse copies of the second peripheral side portions. Each peripheral side portion includes first and second sub-faces which form different angles with the first and second end planes. The first and second sub-faces intersect one another between the first and second end planes to form a line which is parallel to the first and second end planes.

    摘要： A cutting tool has a cutting insert removably secured to a tool body by a fastening member. The cutting insert includes a clamping bore having at least two upper and at least two lower clamping portions intersecting a first and a second horizontal plane, respectively, the first and second horizontal planes being perpendicular to a central axis and spaced apart from each other, and the clamping bore being non-circular at cross-sections taken in the first and second horizontal planes. Upper and lower imaginary lines tangential to the at least two upper and the at least two lower clamping portions, respectively, form zero or acute first and second clamping angles with the central axis, the first and second clamping angles being different. Exactly two upper and exactly two lower clamping portions are in simultaneous clamping contact with an equal number of corresponding clamping zones on the fastening member.

    摘要： A cutting insert (10) has eight identical main cutting edges (26). Four main cutting edges can operate with a positive axial rake and four can operate with a negative axial rake. The cutting insert has two opposing identical end surfaces (12) and a peripheral surface (14) extending between the end surfaces. The cutting insert is square - shaped in end views. Each end surface has four corners (22), two lowered corners (22) and two raised corners (22). A diagonal line (L) passes through the lowered corners of each end surface. For a given orientation of the cutting insert the peripheral surface has a V- shape in views along the two diagonal lines associated with each end surface, the two V- shapes being identical in form and oriented in opposite directions.
