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.*

"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

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.
