Abstract
An indexable insert has a triangular shape with a top surface and a bottom surface, as well as a circumferential surface that connects said the top and bottom surfaces, and cutting edges around the corners. At least in the region of its edges on the top and bottom surface, the indexable insert is identical such that all six cutting edges can be used for the same rotational cutting direction. The secondary cutting edges adjoin two main cutting edges and extend at different angles with respect to the same. In addition, a surface corner milling cutter with a corresponding indexable insert is described.
