摘要: A segmental hard material insert for a working tool has a planar polycrystalline diamond layer (13) having, in its layer plane, a main cutting element (16, 36) and a contact edge (15) located opposite the main cutting element, with the main cutting element (16, 36) having two, facing outwardly, convex cutting sections (17, 27; 37, 47) and a smooth, facing outwardly, concave transitional region (19; 39, 49) connecting the two convex cutting sections (17, 27; 37, 47), and with the apex (20; 40) of the transitional region (19; 39, 47) being located on a central line of the main cutting element (16; 36).
