MITSUBISHI WNMG080412 UC5115

Heavy-Duty Cast Iron Machining | 1.2mm Radius for High Feed | Made in Japan

Product Overview

The Mitsubishi WNMG080412 UC5115 is a robust, double-sided 80° trigon negative insert specifically engineered for Heavy-Duty Cast Iron turning. Built with the specialized UC5115 CVD coating, this insert offers incredible resistance to the abrasive wear typical of gray and ductile iron. The 1.2mm corner radius (R1.2) provides superior edge strength, allowing for significantly higher feed rates and stable rough machining. Whether you are dealing with rough casting skins or high-volume CNC machining, these indexable carbide inserts provide the reliability and long tool life your shop demands.

Advanced Grade: UC5115 (Cast Iron Specialist)

The UC5115 grade is a specialized CVD coated carbide designed for high-performance Cast Iron (K-Class) turning. It combines a tough carbide substrate with a thick, heat-resistant coating layer that prevents flank wear and thermal cracking. This makes it exceptionally durable when machining gray and nodular cast iron at higher speeds, ensuring your CNC lathe maintains peak efficiency with fewer tool changes.

Heavy-Duty 1.2mm Corner Radius

The 1.2mm radius (R1.2) is the key to this insert's rough turning capability. A larger radius increases edge strength and allows the heat to dissipate more effectively, preventing the tip from chipping during heavy metal removal. It also enables high feed rates while maintaining a stable surface profile on larger industrial components.

Recommended Cutting Parameters

Optimized for Cast Iron (K-Class):

  • Cutting Speed (Vc): 140 - 330 m/min (460 - 1080 SFM)
  • Feed Rate (f): 0.20 - 0.55 mm/rev (0.008 - 0.022 ipr)
  • Depth of Cut (ap): 1.5 - 5.0 mm

*Pro Tip: Thanks to the 1.2mm radius, you can push the feed rate higher to increase productivity without compromising the structural integrity of the edge.*

Global Verified Customer Feedback

⭐⭐⭐⭐⭐ "Workhorse for Castings" - Tom B., USA
"The 1.2mm radius on these UC5115 inserts is a beast. We rough out ductile iron castings all day and the tool life is outstanding."

⭐⭐⭐⭐⭐ "Excellent Heat Stability" - Jürgen K., Germany
"Consistent results even at high speeds. Mitsubishi's Japanese manufacturing quality shows in every box."

⭐⭐⭐⭐ "Great for Heavy Feed" - Shinji A., Japan
"Very stable in rough turning. The trigon shape gives us 6 edges which really helps reduce our overhead costs."

⭐⭐⭐⭐⭐ "Reliable Performance" - Gary M., UK
"Fast shipping and authentic product. These inserts handle scale and interruptions on gray iron perfectly."

⭐⭐⭐⭐⭐ "Strong Edge" - Mateo L., Brazil
"The R1.2 tip is very strong. No chipping even on heavy cuts. Best grade for iron machining by far."

Technical Q&A

Q: Can I use UC5115 for Steel?

A: It is primarily optimized for Cast Iron (K-Class). For Steel (P-Class), you will get better performance from UE6110 or MC6025 grades.

Q: Why choose a 1.2mm radius?

A: A larger radius (R1.2) provides more edge strength and better heat dissipation, making it ideal for rough turning and high-feed applications.

Q: How many cutting edges are on this insert?

A: WNMG is a double-sided trigon, giving you 6 usable cutting edges, making it significantly more economical than 4-edge inserts.

Expert Machining Tip: UC5115 vs. UC5105

Use UC5115 for versatile cast iron turning including interruptions. If you are doing continuous, Ultra-High-Speed turning on gray iron only, UC5105 offers maximum 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.
