High-performance stainless steel machining with wiper technology

The CNMG...-W RT255M indexable insert offers a highly effective solution for the economical turning of stainless steel. By incorporating a special wiper cutting edge, the contact area with the workpiece is enlarged, which allows for excellent surface qualities while maintaining high feed rates. This often eliminates the need for time-consuming secondary operations such as grinding or polishing, streamlining the overall manufacturing process.

Applications

This negative turning insert is ideally suited for demanding longitudinal and face turning operations on stainless steels. It is highly valued in the food processing equipment, chemical apparatus engineering, and medical technology sectors, where strict requirements for precision and surface finish apply. The CNMG...-W RT255M handles both continuous cuts and light interruptions reliably and safely.

Special features

The combination of a tough M20–M30 carbide substrate and the wear-resistant PVD coating RT255M ensures a long tool life in stainless steel turning. The integrated wiper geometry significantly reduces machining times and guarantees an excellent finish, sustainably increasing the productivity of modern turning processes. Furthermore, with its four usable cutting edges, it represents a highly economical choice for professional operators.
