Applications
Thanks to its slim 35° shape, the VNMG indexable insert is highly suitable for complex contour machining, copy turning, and tasks that require small inner radii or undercuts. The tool is precisely coordinated for the fine finishing of components made of steel and stainless steel. In industries such as mechanical engineering, automotive, and precision manufacturing, the insert represents a reliable choice for continuous cutting operations.
Special features
The RTC+ Cermet grade is characterized by excellent thermal stability and oxidation resistance, which significantly reduces built-up edges. The special SF chipbreaker geometry ensures controlled chip breaking at low depths of cut and feed rates. This decreases cutting forces, protects the machine spindle, and creates optimal conditions for glossy, dimensionally accurate workpiece surfaces.
