MITSUBISHI WNMG080408-MW UC5115

High-Toughness Cast Iron Specialist | MW Wiper Chipbreaker | Made in Japan

Product Overview

The Mitsubishi WNMG080408-MW UC5115 is a premium double-sided 80° trigon negative insert engineered for the most demanding Cast Iron turning applications. Featuring the legendary UC5115 CVD coating, this insert provides a unique combination of high hardness and extreme impact toughness, making it the ideal choice for interrupted cuts in gray and ductile iron. The MW wiper chipbreaker is optimized for medium-to-heavy cutting with high-feed capabilities, allowing you to achieve superior surface finishes even at double the feed rate on your CNC lathe.

Advanced Grade: UC5115 (The Tough Iron Specialist)

The UC5115 grade is Mitsubishi's dedicated solution for high-productivity Cast Iron turning. Unlike standard grades, UC5115 utilizes a specialized CVD coating that offers incredible resistance to thermal cracking and adhesive wear. This makes it exceptionally durable in heavy interrupted cutting and machining of parts with "sand pockets" or casting crust, ensuring a long and predictable tool life.

MW Wiper Geometry: Double the Productivity

The MW chipbreaker features a Wiper edge. In CNC machining, this allows you to either double your feed rate while maintaining the same surface finish, or achieve a significantly smoother finish at standard feed rates. It is the perfect indexable carbide insert for high-volume production of cast iron components like brake discs, engine blocks, and flywheels.

Recommended Cutting Parameters

Optimized for Cast Iron (K-Class):

  • Cutting Speed (Vc): 120 - 350 m/min (390 - 1150 SFM)
  • Feed Rate (f): 0.25 - 0.60 mm/rev (0.010 - 0.024 ipr)
  • Depth of Cut (ap): 0.8 - 4.5 mm

*Pro Tip: Take advantage of the MW wiper edge by pushing higher feeds to reduce cycle times without sacrificing quality.*

Global Verified Customer Feedback

⭐⭐⭐⭐⭐ "Incredible Feed Rates" - Daniel M., USA
"The MW wiper edge is a game changer. I've doubled my feed on G2 cast iron parts and the finish is still better than standard inserts."

⭐⭐⭐⭐⭐ "Handles Interrupted Cuts" - Stefan K., Germany
"UC5115 is extremely tough. We have zero chipping issues on parts with heavy cross-holes. Very stable Japanese quality."

⭐⭐⭐⭐ "Great for Ductile Iron" - Takumi Y., Japan
"Consistent performance on ductile iron. The tool life is very predictable, which is great for our production runs."

⭐⭐⭐⭐⭐ "Value for Money" - George P., UK
"6 edges on a trigon insert is just smart economics. Paired with this durability, it's our shop's first choice for iron."

⭐⭐⭐⭐⭐ "Authentic Mitsubishi" - Ricardo G., Italy
"Product arrived in original packaging. These perform exactly like the ones from our local distributor but at a better price."

Technical Q&A

Q: Can I use UC5115 for Steel?

A: UC5115 is optimized for Cast Iron (K-Class). For steel turning, we recommend UE6110 or MC6025 for the best performance.

Q: What is a Wiper (MW) insert?

A: A Wiper insert has a flattened contact area on the radius. This "wipes" the surface smooth, allowing for high-feed machining without sacrificing surface quality.

Q: How many cutting edges are available?

A: WNMG is a double-sided trigon, providing a total of 6 usable cutting edges, making it highly cost-efficient.

Expert Machining Tip: UC5115 vs. MC5015

For Continuous High-Speed iron turning, MC5015 is your winner. For Heavy Interrupted Cuts or older machines where toughness is the priority, UC5115 is the better choice.

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?

All our cutting tools and tool holders are manufactured strictly in accordance with ISO 9001 and international industrial standards. Every batch undergoes 100% rigorous quality control testing using high-precision optical measuring equipment to ensure reliable tool life and stable performance in continuous mass production.
