Patent ID: 8858127

Claim:
A cutting insert ( 10 ) comprising two opposing identical end surfaces ( 12 ) and a peripheral surface ( 14 ) extending therebetween, the peripheral surface ( 14 ) comprising four identical side surfaces ( 16 ) and meeting the end surface at peripheral cutting edges ( 24 ), the cutting insert ( 10 ) being square-shaped in end views thereof, each end surface ( 12 ) having four corners ( 22 ), two diagonally opposite lowered corners ( 22 ′) and two diagonally opposite raised corners ( 22 ″); a diagonal line (L1, L2) passes through the lowered corners ( 22 ′) of each end surface ( 12 ); wherein for a given orientation of the cutting insert ( 10 ): the peripheral surface ( 14 ) has a V-shape in a view along the diagonal line (L1) associated with one end surface ( 12 ′), and the peripheral surface ( 14 ) has a V-shape in a view along the diagonal line (L2) associated with the other end surface ( 12 ″); the two V-shapes being identical in form and oriented in opposite directions.
