Featuring a Super ZX multi-layered coating, the new grades AC510U and AC520U are perfect for roughing, finishing, and medium cut machining of super alloy materials. The coating consists of ultra-thin layers of TiAlN and AlCrN, alternately stacked up to 1,000 layers. As a result, higher speed capabilities and greater wear resistance are achieved. The AC510U grade is highly efficient in finish turning of exotic materials, while the AC520U grade is superior in roughing and medium cut machining applications. The grades are available in both molded and ground insert types. Ground tolerance inserts provide improved accuracy, significantly reducing the amount of parts scrapped. As a result, ground inserts are ideal for high-precision applications.
