UC5115 CVD Grade Technology
The UC5115 grade features a specialized thick CVD coating designed for the high-temperature environment of cast iron machining. It offers exceptional resistance to abrasive flank wear and plastic deformation. This makes it the premier choice for gray cast iron and high-tensile ductile iron turning.
Positive Chipbreaker Geometry
Designed with a positive 7° relief angle, this indexable turning insert reduces cutting forces significantly. The chipbreaker is optimized for stable iron turning, ensuring consistent chip evacuation even during high-velocity finishing and semi-finishing passes.
