High-performance cutting for demanding stainless steel tasks

The indexable insert SNMG...-FE RT305 is a well-thought-out solution for finishing operations with continuous cutting. The combination of the proven SNMG basic shape and the specialized FE geometry opens up flexible application possibilities in modern turning. Through the advanced PVD coating of the RT305 grade (M20-M30), the machining of stainless steels is supported reliably, creating ideal conditions for consistent work results and long tool life in series production.

Applications

This carbide insert is geared towards professional use in the finishing of stainless steel workpieces. The FE geometry proves itself particularly well in applications requiring outstanding surface quality, while the RT305 grade ensures reliable performance during continuous cutting. As a result, the cutting insert is ideally suited for precision manufacturing where exact tolerances and consistent dimensional accuracy are demanded.

Special features

A key characteristic of this insert is the alignment of the PVD-coated M20-M30 grade with the specific challenges of stainless steel machining. The combination of the FE cutting geometry with the stable SNMG design ensures excellent chip formation and promotes a light cutting action. This reduces the load on the machine and tool holder, which ultimately contributes to the economic efficiency of the machining process.
