MITSUBISHI WNMG080408-MA UC5115

The Cast Iron Machining Workhorse | 100% Made in Japan

Product Overview

The Mitsubishi WNMG080408-MA UC5115 is a high-performance, double-sided 80° trigon negative insert specifically engineered for stable cast iron turning. Manufactured in Japan, the UC5115 CVD coating is designed to provide extreme toughness and wear resistance when machining abrasive gray cast iron (FC) and ductile cast iron (FCD). Featuring a versatile 0.8mm radius and the MA chipbreaker, this indexable carbide insert ensures consistent tool life and exceptional reliability in heavy-duty CNC machining environments.

UC5115: The Cast Iron Specialist

The UC5115 grade is Mitsubishi's specialized CVD solution for the K-Class material group. Cast iron turning often faces issues with flank wear and micro-chipping due to material abrasiveness. UC5115 uses a unique substrate and coating combination that provides high-speed capability while maintaining the edge toughness required for Cast Iron Machining. It excels in both continuous and light interrupted cuts in FC and FCD materials.

MA Chipbreaker Performance

The MA chipbreaker is an all-purpose medium-range geometry. In cast iron applications, it focuses on reducing cutting resistance and ensuring a high-quality surface finish. The land design is reinforced to withstand the high pressure of CNC turning, ensuring that the indexable carbide insert maintains its geometry throughout the production run.

Recommended Cutting Parameters

Optimized for Cast Iron (K-Class):

  • Cutting Speed (Vc): 150 - 350 m/min (490 - 1150 SFM)
  • Feed Rate (f): 0.15 - 0.45 mm/rev (0.006 - 0.018 ipr)
  • Depth of Cut (ap): 0.5 - 4.0 mm

*Note: UC5115 is highly stable. For higher productivity in gray iron, increase Vc within the recommended range.*

Global Verified Customer Reviews

⭐⭐⭐⭐⭐ "Reliable for Ductile Iron" - Mark S., USA
"UC5115 is our first choice for ductile iron hubs. The wear is very predictable, which is great for lights-out machining."

⭐⭐⭐⭐⭐ "Excellent Finish" - Hans W., Germany
"Best price for authentic Mitsubishi. We saw a significant improvement in surface finish over our previous CVD grade."

⭐⭐⭐⭐ "Very Durable" - Kenji T., Japan
"Made in Japan quality. We use these for gray iron batches and the edge stays sharp for a long time."

⭐⭐⭐⭐⭐ "Economic 6 Edges" - Liam G., Australia
"WNMG is the best value trigon. UC5115 handles the high heat of cast iron turning perfectly. Fast shipping too."

⭐⭐⭐⭐⭐ "Predictable Performance" - Andrej B., Poland
"No surprises with these inserts. They just work. Highly recommended for any cast iron production line."

Technical Q&A

Q: Can I use UC5115 for Steel?

A: UC5115 is specifically optimized for Cast Iron. For Steel turning, we recommend MC6025 or UE6110 for better chip control and tool life.

Q: What is the benefit of the Trigon (W-shape) design?

A: The WNMG shape provides 6 usable cutting edges (3 per side), offering much better economy than standard 4-edged diamond inserts.

Q: Does this grade handle interrupted cuts?

A: Yes, UC5115 is designed for stability and can handle light to medium interruptions in cast iron materials without catastrophic edge failure.

Expert Choice Tip: UC5115 vs MC5005

For High-Speed Finishing in Gray Cast Iron, consider MC5005. For General Purpose & Stable Turning in both Gray and Ductile Iron, UC5115 is the industry standard for reliability.

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.

What is your international shipping policy and typical lead time for orders?

We provide secure worldwide express shipping (via DHL, FedEx, and UPS) with specialized, vibration-proof industrial packaging to ensure tools arrive in perfect condition. In-stock items are dispatched within 24-48 hours, while custom or bulk orders typically have a stable lead time of 15-25 days.

How do you guarantee the quality and tolerance precision of your CNC tools?
