Brilliant Coat is a lubrication film coating that is designed to reduce fracture resistance in the cermet, as well as limit adhesion and the low reactivity contact area between the insert and workpiece. The upshot, according to Sumitomo, is high sheen, ultra-smooth surfaces.
TI500Z inserts are available in positive and negative M- and G-class. M-class negative types have a strong cutting edge giving chip control when cutting materials such as soft steels, while G-class is more suitable for lighter to fine finishing.
