UC5115 Grade Performance
The UC5115 grade is Mitsubishi's premium CVD solution for high-velocity cast iron machining. It features a specialized thick coating layer that serves as a massive heat barrier, preventing plastic deformation. This grade is optimized for the abrasive nature of gray cast iron (ISO K10-K20) and the toughness requirements of ductile iron (ISO K10-K25).
Reinforced Edge Geometry
With a 0.8mm radius, this indexable turning insert provides extreme stability under high pressure. The positive 7° relief angle reduces cutting forces, while the TCMT chipbreaker ensures efficient chip evacuation even in the fragmented chips common in iron turning.
