摘要	In a cutting tool having an indexable cutting insert (20) with exactly four cutting portions (26), the cutting insert is removably securable to an insert holder by a fastener. The cutting insert (20) has two opposing end surfaces (22) with a peripheral side surface (24) extending therebetween, and each cutting portion (26) has a major cutting edge (28) formed by the intersection of a rake surface (30) and a relief surface (32). The peripheral side surface (24) has first and second pairs of opposing side surfaces (34, 36) which include the four relief surfaces (32) and the four rake surfaces (30), respectively. In an end view, four cutting points on the four major cutting edges (28) define the transitions between the first and second pairs of opposing side surfaces (34, 36), and a minimum first length dimension between the second pair of opposing side surfaces (36) is less than six-tenths of a minimum second length dimension between two of the four cutting points.
