Zusammenfassung:A single-sided four-way indexable cutting insert (14) includes a positive basic shape, a rake surface (24), a peripheral surface (28) including four side abutment surfaces (38A, 38B, 38C, 38D), a base bearing surface (26) and a screw hole (30) connecting the rake and base bearing surfaces (24, 26). The insert (14) has an imaginary square frustum which defines a square base containing the cutting insert's base bearing surface (26), and further defines four isosceles trapezoid side surfaces (54A, 54B, 54C, 54D) respectively containing the cutting insert's (14) four side abutment surfaces (38A, 38B, 38C, 38D). A material volume VF of the cutting insert (14) and a void volume VS of the insert (14) fulfill the condition VS/VF ≥ 0.25.
