<p>A multiply indexable cutting insert for a drilling tool includes a body defined by two plane-parallel outside faces disposed perpendicular to an insert axis. Each outside face includes a plurality of edges defining a substantially triangular outer contour. Each edge includes a respective main cutting edge extending substantially over the entire length of the respective edge. The body has a rotational symmetry in respect of a 120° rotation about the insert axis and a rotational symmetry in respect of a 180° rotation transversely in relation to the insert axis.</p> |
