Kennametal’s Beyond Drive inserts suit SS and CI
Beyond Drive inserts from Kennametal feature a bronze TiOCN top coating that increases wear resistance and functions as a wear indicator, it is said. Designed for cast irons and stainless steels, Beyond Drive inserts feature a proprietary post-coat surface treatment that improves edge toughness, reliability and depth-of-cut notch resistance, says Kennametal, while a micro-polished surface reduces friction and workpiece sticking (BUE). A fine-grained alumina layer allows for increases in cutting speed, improving productivity and reliability at high cutting temperatures, it is claimed.
With Beyond Drive, adding a titanium oxy-carbonitride outer coating (TiOCN) not only increases wear resistance and abrasion resistance, its bronze colour is also an effective wear indicator.
In a test at a plant producing cast iron transmission components, with no change in feed, spindle speed, or depth of cut, Beyond Drive completed 325 pieces per cutting edge compared with 200 pieces using the plant´s current inserts.
