FOTO5_KennametalNew Beyond Drive™ cutting tool inserts from Kennametal are helping component suppliers expand and thrive in this environment with enhanced performance and extended tool life that mean many more finished pieces per cutting edge. Specifically designed for cast irons, steels, and stainless steels that make up many critical components over a variety of industries, Kennametal’s new BeyondDrive inserts feature a proprietary post-coat surface treatment that improves edge toughness, reliability, and depth-of-cut notch resistance, and a micro-polished surface to reduce friction and workpiece sticking (BUE).

A fine-grained alumina layer allows for increases in cutting speed, improving productivity and reliability at high cutting temperatures. Adding a new titanium oxy-carbonitride outer coating (TiOCN) not only increases wear- and abrasion-resistance, its bronze color is also an effective wear indicator. All new Beyond inserts are CVD (chemical vapor deposition) coated, but whereas conventional CVD coatings are under tensile stress, Beyond inserts undergo a proprietary post-coat treatment on all surfaces to reduce this stress, which improves coating adhesion and reduces micro-chipping.
