MITSUBISHI WNMG080404-MA MC6025

Professional Steel Machining Specialist | 100% Made in Japan

Product Overview

The Mitsubishi WNMG080404-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 0.4mm 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.*

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.
