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.
