MITSUBISHI WNMG080402-FP MC6025

Precision Steel Finishing Specialist | 0.2mm Corner Radius | Made in Japan

Product Overview

The Mitsubishi WNMG080402-FP MC6025 is a high-precision double-sided 80° trigon negative insert, specifically engineered for fine finishing of Steel (P-class). Featuring a sharp 0.2mm corner radius and the high-performance MC6025 CVD coating, this insert excels in applications requiring tight tolerances and mirror-like surface finishes. The FP chipbreaker is the industry standard for light depths of cut, ensuring stable chip control even in high-speed CNC machining environments. Ideal for carbon steel, alloy steel, and mild steel components.

Advanced Grade: MC6025 (The Steel Professional)

The MC6025 grade is Mitsubishi's premier CVD solution for Steel turning. Engineered for a perfect balance between wear resistance and toughness, it utilizes a specialized coating layer that resists plastic deformation and crater wear. This ensures high-speed efficiency and reliable tool life even when machining alloy steels under variable cutting conditions.

FP Finishing Chipbreaker

The FP chipbreaker is a dedicated geometry for light finishing. It features a sharp rake angle and a narrow chip pocket, designed to break chips effectively at low feed rates and shallow depths. In CNC lathe operations, this prevents "bird-nesting" of long chips, protecting the workpiece surface from scratches and ensuring high precision machining results.

Recommended Cutting Parameters

Optimized for Steel (P-Class):

  • Cutting Speed (Vc): 150 - 320 m/min (490 - 1050 SFM)
  • Feed Rate (f): 0.05 - 0.20 mm/rev (0.002 - 0.008 ipr)
  • Depth of Cut (ap): 0.2 - 1.5 mm

*Pro Tip: For the best surface Ra, use a high Vc and keep the feed rate below 0.12 mm/rev.*

Global Verified Customer Feedback

⭐⭐⭐⭐⭐ "Perfect for tight tolerances" - Mark S., USA
"I used these for some aerospace steel parts that required a very specific finish. The 0.2mm radius is incredibly sharp and accurate."

⭐⭐⭐⭐⭐ "Mirror Surface" - François B., France
"Excellent for final passes. No more vibration issues, and the chip breaking on mild steel is the best I've seen in years."

⭐⭐⭐⭐ "Great Stability" - Kenji T., Japan
"Consistent quality from Mitsubishi. We run these on our CNC automation line for small steel pins, and the wear is very predictable."

⭐⭐⭐⭐⭐ "Economic 6 Edges" - Liam O., UK
"A finishing insert with 6 edges! Huge savings compared to standard diamond inserts. The FP breaker works exactly as advertised."

⭐⭐⭐⭐⭐ "Authentic Product" - Ivan R., Russia
"Genuine Mitsubishi inserts. Performance is top-tier. Shipping was fast and the packaging was original."

Technical Q&A

Q: Can I use this for Stainless Steel?

A: While it can cut stainless, it is optimized for Steel (P-Class). For high-volume stainless finishing, MC7025 is a more durable choice.

Q: What is the benefit of the 0.2mm radius?

A: It allows for incredibly fine finishing and minimizes cutting pressure, which is perfect for thin-walled parts or finishing small details.

Q: Why choose WNMG over CNMG?

A: WNMG offers 6 usable cutting edges instead of 4, making it far more cost-effective for your machine shop production.

Expert Machining Tip: MC6025 vs. MC6015

Use MC6025 for versatile, stable finishing on most steels. If you are doing High-Speed Finishing on hard carbon steels only, MC6015 offers slightly higher 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.

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.
