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

How do I choose the correct specification?

When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.

How can I check compatibility with my existing setup?

For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.

What quantity and price unit am I ordering?

Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.

How should I choose cutting parameters?

Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.

Are bulk discounts available?

Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.

When will my order ship and arrive?

According to our shipping policy, orders are typically processed and shipped within 1–3 business days after confirmation. Delivery generally takes 5–20 business days, depending on your destination and shipping method. Customs clearance or unforeseen delays may affect delivery times. A tracking number is sent by email after shipment.
