UC5115 CVD Grade
The UC5115 grade is a specialized CVD turning insert material featuring a thick alumina coating layer. This provides exceptional resistance to high-temperature oxidation and flank wear when machining abrasive cast iron. It is the first choice for stable turning in high-speed, continuous cutting conditions.
Chipbreaker Geometry
The standard TNMG chipbreaker on this indexable turning insert is optimized for the powdery, brittle chips produced by cast iron. By effectively managing chip flow and heat dissipation, it prevents the edge deformation often seen in lower-quality tools.
