Beyond Drive cutting tool inserts from Kennametal are specifically designed for cast irons, steels and stainless steels that make up many critical components over a variety of industries. The inserts are a product of ongoing design leadership, engineering, materials science and manufacturing directly targeted to the needs of component manufacturers.

Beyond Drive inserts feature a 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.

With Beyond Drive, 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. Depending on the application, field tests are showing anywhere between 30 percent and 125 percent more parts per edge, the company says.

The inserts are CVD (chemical vapor deposition) coated, but whereas conventional CVD coatings are under tensile stress, Beyond inserts undergo a post-coat treatment on all surfaces to reduce this stress, which improves coating adhesion and reduces micro-chipping, the company says.
