Applications
This model opens up flexible operational possibilities for contouring and longitudinal turning of high-strength alloys. It is designed for professional use and supports efficient workflows in both batch and single-part production when heat-resistant special materials need to be machined under continuous cutting conditions.
Special features
The RT110S cutting grade is notable for its thermal stability and wear resistance. In combination with the SM geometry designed for medium machining, the negative insert creates a solid basis for a highly consistent machining process, even in demanding cutting tasks.
