Mitsubishi TNMG160404 UC5115 Insert
High-Speed Cast Iron Turning | Multi-Edge Triangular | UC5115 CVD Grade
What is the best insert for high-speed turning of cast iron?
The Mitsubishi TNMG160404 UC5115 is a premium double-sided triangular carbide turning insert specifically engineered for the demanding world of cast iron machining. Utilizing the specialized UC5115 CVD coated grade, this tool offers exceptional wear resistance and thermal stability when processing gray and ductile cast iron (ISO K). With 6 usable cutting edges, it provides maximum economic efficiency. Manufactured in Japan, this CNC turning insert is designed to maintain sharp edge integrity even under high-temperature, high-speed continuous cutting conditions.
UC5115 Cast Iron Grade
A dedicated CVD grade featuring an ultra-thick Al2O3 layer that provides a powerful heat shield, significantly extending tool life in dry or high-speed machining.
Stabilized Cutting Edge
Engineered to resist the abrasive nature of cast iron, preventing premature crater wear and edge chipping during continuous passes.
6-Edge Economy
The double-sided triangular (60°) geometry ensures a low cost-per-edge, making it ideal for high-volume industrial production.

8. FAQ - Professional Support
Q: Is UC5115 suitable for steel?
A: UC5115 is optimized for cast iron. For steel turning, we recommend Mitsubishi grades like UE6110 or MC6025.
Q: Can this insert handle interrupted cuts?
A: UC5115 is best for continuous cutting. For heavy interrupted cuts, the UC5105 or tougher substrates may be preferred depending on the shock level.
Q: What is the benefit of the Al2O3 coating?
A: The thick Alumina layer provides high temperature resistance, preventing thermal cracking and deformation during high-speed machining.
Expert Insight: The Cast Iron Edge
Cast iron machining is notoriously abrasive. The UC5115 grade utilizes an extra-thick CVD coating that acts as a sacrificial barrier, protecting the carbide core from wear. For finishing passes where dimensional stability is key, the TNMG160404 geometry provides the perfect balance of sharpness and strength.
