A cutter insert for milling tools includes a base body having a base surface, a top surface, and four side surfaces. The four side surfaces, together with each of the base surface and the top surface, define respective cutting edges. The base body is twisted about each of two perpendicular, coplanar axes of the base body. Each side surface has two opposite corner edges that are offset from one another in a direction parallel to a center axis of the base body.
