MITSUBISHI WNMG080412-GH UC5115

Heavy-Duty Cast Iron Roughing Expert | 1.2mm Corner Radius | Made in Japan

Product Overview

The Mitsubishi WNMG080412-GH UC5115 is a powerhouse double-sided 80° trigon negative insert, specifically engineered for the most demanding cast iron turning applications. Featuring a robust 1.2mm corner radius for maximum edge strength and the specialized UC5115 CVD coating, this insert excels in high-speed roughing of gray and ductile iron. The GH chipbreaker provides a reinforced cutting edge, making this indexable carbide insert a premier choice for CNC machining environments where high metal removal rates and exceptional tool life are required.

Advanced Grade: UC5115 (Wear Resistant CVD)

The UC5115 grade represents the pinnacle of Mitsubishi’s CVD technology for cast iron. It features a high-density coating structure that resists the abrasive nature of gray and ductile iron particles. This grade is optimized for continuous cutting at high speeds, significantly reducing crater wear and plastic deformation on your CNC lathe.

GH Chipbreaker Geometry

The GH (General Heavy) chipbreaker is purpose-built for heavy roughing. With a robust cutting edge and land width, it handles high depth-of-cut (ap) and aggressive feed rates. The large 1.2mm radius (12) further enhances edge strength, allowing the insert to survive heavy interrupted cuts and rough casting surfaces with ease.

Recommended Cutting Parameters

Optimized for Cast Iron (K-Class):

  • Cutting Speed (Vc): 150 - 350 m/min (490 - 1150 SFM)
  • Feed Rate (f): 0.25 - 0.60 mm/rev (0.010 - 0.024 ipr)
  • Depth of Cut (ap): 1.2 - 4.5 mm

*Pro Tip: Thanks to the 1.2mm radius, you can push higher feed rates while maintaining process security.*

Verified Global Customer Reviews

⭐⭐⭐⭐⭐ "Heavy Duty Performance" - Mark S., USA
"The 1.2mm radius on UC5115 is incredible. We rough out ductile iron housings all day and the edge holds up perfectly."

⭐⭐⭐⭐⭐ "Consistent Tool Life" - Dieter B., Germany
"Very reliable CVD grade. We run these at high speeds and the wear is very predictable. Original Japanese quality."

⭐⭐⭐⭐ "Great Chip Control" - Kenji T., Japan
"Even on rough castings, the GH breaker manages chips well. No edge chipping observed so far."

⭐⭐⭐⭐⭐ "Cost-Effective 6 Edges" - Liam J., Australia
"WNMG is the best value. 6 edges with UC5115 toughness makes this a very economical choice for our shop."

⭐⭐⭐⭐⭐ "Original Packaging" - Pavel D., Poland
"Authentic Mitsubishi inserts. Fast shipping and they perform exactly as the technical data suggests."

Technical Q&A

Q: Can I use UC5115 for Steel?

A: UC5115 is specialized for Cast Iron (K-Class). For steel, please use UE6110 or MC6025 for better results.

Q: Why choose the 1.2mm radius over the 0.8mm?

A: The 1.2mm radius provides significantly higher edge strength, making it superior for heavy roughing and interrupted cuts.

Q: Is this insert compatible with standard holders?

A: Yes, it fits any standard MWLNR / DWLNR turning tool holder designed for 08 size WNMG inserts.

Expert Machining Tip: UC5115 vs MC5015

For General High-Speed Cast Iron roughing, UC5115 is legendary. For Highly Abrasive Ductile Iron finishing, consider the MC5015 grade for improved 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.
