Abstract: A double-sided cutting insert (21) according to the present invention includes two end surfaces (25) that each includes major rake surfaces (37) adjacent major cutting edges (33) that form first angles (α) with planes of the major side surfaces, and a central support surface (29) forming a second angle (β) with the planes of the major side surfaces. Each end surface further includes major intermediate surfaces (41) between the major rake surfaces and the central support surface. The major intermediate surfaces forming third angles (γ) with the planes of the major side surfaces that are greater than the first angles (α) and smaller than the second angles (β) when measured in a central plane (CP) that extends along a central axis (A) of a hole (35) and is generally perpendicular to the planes of the major side surfaces and planes of the central support surfaces. The present invention also relates to a cutting tool.
