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.

Technical FAQ & Buying Guide

Are your carbide inserts interchangeable with major brands like Sandvik, Iscar, or Kennametal?

Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.

How do I choose the correct insert grade and chipbreaker for machining Stainless Steel (M) vs. Carbon Steel (P)?

We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:

  • For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
  • For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
What are the recommended cutting speed (Vc) and feed rate (f) parameters to maximize tool life?

The optimal cutting parameters vary depending on the workpiece hardness and operation type:

  • For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
  • For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
Do you offer bulk discounts or wholesale pricing for machine shops and distributors?

Yes, we support machine shops, distributors, and global buyers with tiered wholesale pricing and competitive volume discounts. We also provide OEM custom manufacturing solutions for tool holders and carbide inserts based on your technical drawings. Contact our team to request a quick B2B quotation.
