Coated Grades Suited For Turning Exotic Materials

Related Suppliers

Featuring a Super ZX multi-layered coating, Sumitomo Electric Carbide's AC510U and AC520U grades are suited for roughing, finishing and medium-cut machining of super alloy materials. The coating consists of thin layers of TiAlN and AlCrN alternately stacked to 1,000 layers, resulting in high speed capabilities and great wear resistance.


The AC510U grade is efficient in finish turning of exotic materials, while the AC520U grade is best used 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.
