Applications

Thanks to its dedicated FE geometry, this turning insert is highly suitable for fine contour and longitudinal turning of stainless steels. It is the proper choice for continuous cutting paths without interruptions, where precise chip evacuation and strict dimensional accuracy are crucial. Typical fields of application include mechanical engineering, medical technology, and general parts manufacturing, where demanding materials must be finished with high reliability.

Special features

A major advantage of this insert lies in the balanced combination of toughness and wear resistance, achieved by the modern PVD coating of the M20-M30 grade. The targeted design for continuous cuts helps to minimize unnecessary vibrations, thus promoting a clean surface finish. Supplied in a practical 10-piece packaging unit, it ensures you are always well-equipped during ongoing production.
