Applications

This turning insert is geared towards process-reliable steel machining in a professional environment. It proves itself particularly in applications that require a fine to medium depth of cut. Thanks to its tailored geometry, even tough or soft steel alloys can be machined with control, emphasizing the tool's universal character in everyday workshop operations.

Special features

The CVD coating of the RT325G grade provides high wear resistance, which has a positive influence on tool life. Designed as a negative turning insert, the CNMG shape offers the economic advantage of double-sided cutting edges. The specifically engineered chipbreaker helps to prevent long chips and generates short-breaking chips instead, which is beneficial for smooth turning processes.
