摘要
An indexable milling or drilling insert having a 180-degree rotational symmetry about each of the first, second and third axes (X, Y, Z) of a three-dimensional euclidean space. The insert has opposite first and second main surfaces and a peripheral surface extending therebetween. Each main surface has a main abutment surface and at least two rake surfaces. The insert has a through clamping bore which extends along the third axis and opens out to the main surfaces. The peripheral surface has two opposite front surfaces connected to two opposite side surfaces. Each front surface has a pair of outward abutment surfaces and each side surface has a pair of at least partially planar inward abutment surfaces. Each pair of outward abutment surfaces converge outwardly away from the third axis and each pair of inward abutment surfaces converge inwardly towards the third axis.
