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.

Recommended Cutting Parameters (UC5115 Grade)

  • Cutting Speed (Vc): 150 - 350 m/min (Highly efficient in Ductile Iron)
  • Feed Rate (f): 0.10 - 0.35 mm/rev (Depending on chipbreaker)
  • Depth of Cut (Ap): 0.5 - 3.5 mm

*Note: UC5115 is optimized for dry cutting due to its high thermal barrier properties.*

4. Product Applications

  • High-speed turning of ductile cast iron (FCD).
  • Continuous cutting of gray cast iron (FC) engine blocks.
  • Machining of heavy industrial valves and pump housings.
  • Excellent for high-volume brake rotor and drum production.

5. Equipment Compatibility

Standard fit for WTJNR/L, MTJNR/L, and DTJNR/L tool holders. Compatible with standard CNC turning centers using 16mm triangular clamping systems.

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

How do I choose the correct specification?

When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.

How can I check compatibility with my existing setup?

For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.

What quantity and price unit am I ordering?

Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.

How should I choose cutting parameters?

Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.

Are bulk discounts available?

Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.

When will my order ship and arrive?

According to our shipping policy, orders are typically processed and shipped within 1–3 business days after confirmation.
