MITSUBISHI WNMG080408 UC5115

Professional Cast Iron Machining | Superior Wear Resistance | Made in Japan

Product Overview

The Mitsubishi WNMG080408 UC5115 is a high-durability double-sided 80° trigon insert specifically engineered for Cast Iron turning (K-Class). Equipped with the industry-leading UC5115 CVD coating, this insert is built to withstand the highly abrasive nature of gray and ductile cast iron. With a robust 0.8mm corner radius, it provides excellent edge strength for medium cutting to light roughing. These indexable carbide inserts are essential for CNC machining facilities requiring long tool life and consistent precision machining in heavy-duty industrial casting environments.

Grade: UC5115 (The Cast Iron Master)

The UC5115 grade is Mitsubishi's premier solution for Cast Iron (K-Class) turning. Cast iron machining presents unique challenges such as abrasive wear and rapid heat generation. UC5115 utilizes a specialized CVD coating with high thermal stability and a tough carbide substrate to resist flank wear and thermal cracking. This ensures your CNC lathe maintains strict tolerances during long production runs in gray or nodular iron.

Enhanced 0.8mm Radius Strength

The 0.8mm corner radius provides a larger contact area, increasing edge strength and heat dissipation. This makes the WNMG080408 highly effective for medium cutting applications where higher feed rates are required. In CNC machining, this geometry helps achieve a stable balance between metal removal rate and surface quality.

Recommended Cutting Parameters

Optimized for Cast Iron (K-Class):

  • Cutting Speed (Vc): 160 - 350 m/min (525 - 1150 SFM)
  • Feed Rate (f): 0.15 - 0.45 mm/rev (0.006 - 0.018 ipr)
  • Depth of Cut (ap): 1.0 - 4.5 mm

*Pro Tip: For high-speed gray iron turning, stay at the upper end of Vc for maximum productivity. For ductile iron with skin, reduce speed for the first pass.*

Global Verified Customer Feedback

⭐⭐⭐⭐⭐ "Best for Cast Iron" - James R., USA
"We turn massive ductile iron pulleys and UC5115 is the only grade that holds up. The tool life is incredible compared to standard grades."

⭐⭐⭐⭐⭐ "Stable and Consistent" - Lars H., Germany
"Consistent results across every batch. Mitsubishi Japan always delivers the highest quality. No surprises on the machine."

⭐⭐⭐⭐ "Great for Roughing" - Yuki T., Japan
"The 0.8mm radius is very robust. We use it for medium roughing on gray iron castings with great success."

⭐⭐⭐⭐⭐ "Unbeatable Value" - Mark S., UK
"6 usable edges per insert makes the WNMG trigon a cost-saver. Combined with the UC5115 durability, it's a win."

⭐⭐⭐⭐⭐ "Original and Authentic" - Jan V., Belgium
"Received original Mitsubishi packaging. The high-speed performance is exactly as described. Very happy with the purchase."

Technical Q&A

Q: Can I use UC5115 for Steel parts?

A: It is primarily designed for Cast Iron (K-Class). For steel applications, we strongly recommend MC6025 or UE6020 for better performance.

Q: Why is 0.8mm radius better for iron than 0.4mm?

A: Cast iron can be very abrasive. The 0.8mm radius offers a stronger edge that resists chipping and manages heat better during medium-to-rough cutting.

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 general-purpose cast iron turning and light interruptions. For Ultra-High-Speed continuous turning on gray iron only, UC5105 provides 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.
