MITSUBISHI WNMG080404 UC5115

Cast Iron Machining Specialist | High Wear Resistance | Made in Japan

Product Overview

The Mitsubishi WNMG080404 UC5115 is a high-performance double-sided 80° trigon insert specifically engineered for the demanding environment of Cast Iron turning (K-Class). Featuring the specialized UC5115 CVD coating, this insert excels in providing maximum wear resistance against the abrasive nature of gray and ductile cast iron. With a sharp 0.4mm corner radius, it is designed for precision machining and light to medium finishing passes. These indexable carbide inserts are a staple for CNC machining shops looking to increase tool life and productivity in industrial casting applications.

Grade: UC5115 (The Cast Iron Expert)

The UC5115 grade features a specialized CVD coating that targets the unique challenges of Cast Iron (K-Class) turning. Gray and ductile irons are highly abrasive and generate significant heat. UC5115 uses a tough carbide substrate paired with a coating that resists thermal cracking and flank wear, maintaining dimensional stability during long runs. This ensures that your CNC turning operations remain uninterrupted and cost-effective.

Precision 0.4mm Radius

The 0.4mm corner radius is perfect for finishing and semi-finishing passes. It minimizes cutting pressure and vibration, which is crucial for achieving high surface Ra quality on cast iron parts. When utilized in CNC machining, this geometry provides a clean cut and excellent chip management.

Recommended Cutting Parameters

Optimized for Cast Iron (K-Class):

  • Cutting Speed (Vc): 150 - 320 m/min (490 - 1050 SFM)
  • Feed Rate (f): 0.10 - 0.35 mm/rev (0.004 - 0.014 ipr)
  • Depth of Cut (ap): 0.5 - 3.0 mm

*Pro Tip: For gray cast iron, higher speeds (Vc) can be used to improve productivity. For ductile iron, keep speeds moderate to preserve edge toughness.*

Technical Q&A

Q: Can I use UC5115 for Steel?

A: While it can cut steel, it is optimized for Cast Iron (K-Class). For steel applications, we recommend the MC6025 or UE6020 grades.

Q: Why is UC5115 better for iron?

A: It has a specialized layer that prevents the abrasive dust of cast iron from eating away the carbide substrate, which is the main cause of tool failure in iron turning.

Q: How many edges does the WNMG have?

A: The WNMG trigon shape is double-sided, giving you 6 usable cutting edges, making it 50% more economical than standard diamond inserts.

Expert Machining Tip: UC5115 vs. UC5105

Use UC5115 for versatile cast iron turning, including interrupted cuts. If you are doing continuous, Ultra-High-Speed turning on gray iron only, UC5105 offers even higher wear resistance.

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.
