High-Performance Cutting Solution for Finishing Operations

The indexable insert CNMG...-FE RT305 is specifically designed for professional use in stainless steel machining. With its precise CNMG shape and targeted engineering for continuous as well as slightly interrupted cutting, it promotes highly efficient turning processes during finishing. The applied PVD grade RT305 (M20-M30) features modern coating technology that enhances wear resistance and contributes to an excellent surface finish. Consequently, this cutting tool proves to be a practical choice for manufacturers who rely on process stability when producing stainless steel components.

Applications

Thanks to the highly capable FE geometry, this turning insert is excellently suited for fine contour machining in demanding mechanical engineering, food industry equipment, or medical technology. Wherever corrosion-resistant alloys are reliably processed and strict requirements are placed on the final surface finish, the CNMG-FE model truly demonstrates its capabilities.

Special features

A key feature of the CNMG...-FE RT305 is the precise interplay between the solid carbide substrate and the specialized PVD coating. This ensures adequate temperature resistance during finishing operations. Additionally, the cutting edge preparation, which is perfectly adapted for continuous and slightly interrupted cuts, supports orderly chip evacuation, noticeably reducing machining obstacles.
