MITSUBISHI WNMG080408 NX2525

Premium Cermet Finishing Specialist | High-Gloss Surface | Made in Japan

Product Overview

The Mitsubishi WNMG080408 NX2525 is a high-performance double-sided 80° trigon insert engineered for the ultimate surface finish in Steel turning. Utilizing the advanced NX2525 Cermet grade (Ceramic + Metal), this insert offers a low affinity for workpiece materials, drastically reducing built-up edge and friction. This makes it the premier choice for precision machining where mirror-like Ra finishes and tight dimensional tolerances are required. Ideal for high-speed CNC machining of carbon, alloy, and mild steels.

Material: NX2525 Cermet Technology

NX2525 is a premium micro-grain Cermet grade. By combining ceramic particles with a metallic binder, Mitsubishi has created a material with higher thermal stability and hardness than standard tungsten carbide. This indexable cermet insert maintains a sharp cutting edge even at higher temperatures, ensuring that long-run production remains dimensionally accurate without the frequent need for tool offsets.

Surface Finish Performance

Because Cermet has a low affinity for iron, it prevents the chemical "welding" of steel to the tool tip. This results in incredibly clean cutting action. The 0.8mm radius of the WNMG080408 provides a robust edge strength suitable for both light roughing and high-quality finishing passes on CNC turning equipment.

Recommended Cutting Parameters

Optimized for Steel (P-Class) Finishing:

  • Cutting Speed (Vc): 140 - 300 m/min (460 - 985 SFM)
  • Feed Rate (f): 0.10 - 0.30 mm/rev (0.004 - 0.012 ipr)
  • Depth of Cut (ap): 0.3 - 2.0 mm

*Pro Tip: For the best visual result, use high cutting speeds and ensure your machine has sufficient rigidity to minimize vibration.*

Global Verified Customer Feedback

⭐⭐⭐⭐⭐ "Mirror Surface on 4140" - Robert T., USA
"I used these for finishing 4140 alloy steel. The result was unbelievable. It saved us an entire polishing step."

⭐⭐⭐⭐⭐ "Predictable and Stable" - Hans G., Germany
"NX2525 is very stable. We ran 200 parts and the diameter didn't change at all. Excellent Japanese quality."

⭐⭐⭐⭐ "No Built-up Edge" - Akira K., Japan
"Very clean cut on mild steel. Cermet really makes a difference for aesthetics."

⭐⭐⭐⭐⭐ "Best ROI for Finishing" - Liam N., Australia
"Getting 6 edges with WNMG geometry in a Cermet grade is a great deal. Highly recommend."

⭐⭐⭐⭐⭐ "Fast Shipping & Original" - Ivan P., Poland
"Genuine Mitsubishi box. Arrived fast and works exactly like the catalog says."

Technical Q&A

Q: Is NX2525 better than coated carbide?

A: For finishing, yes. It provides a better Ra finish and prevents built-up edge. However, for heavy roughing, coated carbide is tougher.

Q: Should I use coolant with Cermet?

A: Cermet can be used dry or with high-pressure coolant. Avoid "intermittent" coolant (splashing) as it can cause thermal cracking.

Q: How many cutting edges are available?

A: WNMG is a double-sided trigon, giving you 6 usable cutting edges, making it 50% more efficient than CNMG.

Expert Machining Tip: Cermet (NX2525) vs. Carbide (MC6025)

Use NX2525 for final finishing passes where surface gloss and precision are paramount. Use MC6025 for general turning and metal removal efficiency.

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.
