MITSUBISHI WNMG080408-MA MC6025

Professional Steel Machining Specialist | 100% Made in Japan

Product Overview

The Mitsubishi WNMG080408-MA MC6025 is a high-performance, double-sided 80° trigon negative insert designed for stable and efficient steel turning. Engineered in Japan, the MC6025 CVD coating (multi-layered Al2O3 + TiCN) offers a superior balance of wear resistance and toughness. This indexable carbide insert is specifically optimized for P-class materials (Carbon and Alloy Steels), providing long tool life even in unstable or interrupted cutting conditions. With its MA chipbreaker and 0.8mm radius, it is your go-to solution for medium-duty CNC machining.

Optimized Grade: MC6025 (CVD Coating)

The MC6025 grade is Mitsubishi's benchmark for stable steel turning. By utilizing "Nano-Texture" technology within the CVD layer, it prevents crater wear and edge chipping. This grade is highly versatile, excelling in both continuous high-speed cutting and light interrupted cuts. It is the ideal "all-rounder" for carbon steel, alloy steel, and mild steel.

MA Chipbreaker Geometry

The MA (Medium-range) chipbreaker is designed for versatility. It balances a sharp cutting edge for low cutting resistance with a land that reinforces the edge stability. It provides excellent chip control in medium-duty turning, protecting your workpiece surface and CNC lathe tool holder from chip wrapping.

Recommended Cutting Parameters

Optimized for General Steel (P-Class):

  • Cutting Speed (Vc): 150 - 320 m/min (490 - 1050 SFM)
  • Feed Rate (f): 0.12 - 0.35 mm/rev (0.005 - 0.014 ipr)
  • Depth of Cut (ap): 0.5 - 3.5 mm

*Note: MC6025 offers a wide machining window. Adjust speed based on material hardness.*

"MC6025 is the best choice for general steel turning. Surface finish is top-tier."

Technical Q&A

Q: Why use the W-shape (Trigon) over CNMG?

A: The 80° trigon provides 6 usable cutting edges compared to 4 for CNMG, significantly lowering your cost per edge while maintaining strength.

Q: Is MC6025 suitable for heavy roughing?

A: MC6025 is best for medium-range machining. For heavy roughing, consider a 1.2mm radius or the tougher MC6035 grade.

Q: Does this work for stainless steel?

A: While it can do light stainless, we recommend MP735 or MC7025 for dedicated stainless steel turning.

Expert Performance Tip: Grade Choice

For High-Speed Continuous Turning, use MC6015. For General/Stable Steel Turning, MC6025 is the benchmark. For Interrupted/Heavy Cuts, choose MC6035.

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.
