Patent ID: 8753045

Claim:
A cutting insert ( 14 ), comprising: two opposing end surfaces ( 16 ) and a peripheral surface ( 20 ) extending therebetween, the peripheral surface ( 20 ) and the end surfaces ( 16 ) meeting at respective edges ( 18 ), at least a section of which forms respective cutting edges ( 18 ′) with a rake surface being formed on the end surface ( 16 ), the peripheral surface ( 20 ) comprising at least a first side surface ( 22 ′); wherein: the first side surface ( 22 ′) comprises a first set of abutment bars ( 24 ′) extending thereon and protruding outwardly with respect to a background surface ( 25 ) of the first side surface ( 22 ′), each abutment bar of the first set of abutment bars ( 24 ′) comprising a respective outer surface ( 26 ′) for engaging a major wall ( 28 ) of an insert pocket ( 12 ) that releasably retains the cutting insert ( 14 ) therein; the outer surfaces ( 26 ′) are generally coplanar and define an imaginary plane (P 1 ) that does not intersect any portion of the first side surface ( 22 ′) apart from the outer surfaces ( 26 ′); and the abutment bars ( 24 ′) are spaced apart from said respective edges ( 18 ) where the peripheral surface ( 20 ) meets the end surfaces ( 16 ).
