MITSUBISHI WNMG080404-MA UE6120

Toughness Specialist for Interrupted Steel Cutting | 100% Made in Japan

Product Overview

The Mitsubishi WNMG080408-MA UE6120 is a high-toughness, double-sided 80° trigon negative insert optimized for interrupted steel turning and unstable machining conditions. Engineered in Japan, the UE6120 CVD coating provides industry-leading impact resistance, preventing edge chipping even when machining keyed shafts or hex bars. Featuring the MA chipbreaker and a precise 0.4mm radius, this indexable carbide insert is the professional choice for reliability in demanding CNC machining environments.

Interruption Grade: UE6120 (Tough CVD)

The UE6120 grade is Mitsubishi's premier solution for heavy interrupted steel turning. Unlike high-speed continuous grades, UE6120 focuses on substrate toughness and coating adhesion. It is optimized for the P25-P35 range, providing superior shock resistance during non-continuous cuts in carbon and alloy steels. This prevents sudden fracture and ensures predictable tool life in messy or unstable setups.

MA Chipbreaker Geometry

The MA chipbreaker is an all-purpose medium-range geometry. It provides a sharp cutting action for low resistance while maintaining a land that reinforces the edge against impact. It excels at chip control even when the cut depth varies, ensuring chips don't wrap around the CNC turning tool holder.

Recommended Cutting Parameters

Optimized for Steel (P-Class) Interrupted Cuts:

Cutting Speed (Vc): 120 - 240 m/min (395 - 785 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: UE6120 is designed for stability. If doing light finishing on stable parts, consider higher speeds.*

Global Verified Customer Reviews

⭐⭐⭐⭐⭐ "Solved my Chipping Issues" - David K., USA
"Was struggling with broken inserts on keyed shafts. UE6120 fixed it instantly. Toughness is unmatched for interrupted cuts."

⭐⭐⭐⭐⭐ "Genuine Japanese Quality" - Hans G., Germany
"Exactly what I expect from Mitsubishi. The MA chipbreaker handles the gummy steel chips beautifully. Very stable."

⭐⭐⭐⭐ "Great for Versatile Work" - Sato M., Japan
"Reliable performance for everyday general purpose steel turning. Hard to find a better 6-edge trigon."

⭐⭐⭐⭐⭐ "Incredible Cost per Edge" - Liam F., Australia
"WNMG shape is my favorite for economy. 6 usable edges and this UE6120 grade lasts forever on 4140 steel."

⭐⭐⭐⭐⭐ "Fast Delivery & Original" - Andrej P., Poland
"Verified original boxes. These inserts shine when the setup isn't 100% rigid. Great impact resistance."

Technical Q&A

Q: When should I choose UE6120 over UE6110?

A: Choose UE6120 for interrupted cuts or unstable setups. Choose UE6110 for high-speed, continuous, stable production runs.

Q: Is this insert double-sided?

A: Yes, this is a negative trigon (W-shape) insert, providing 6 usable cutting edges for maximum cost efficiency.

Q: Does it work for stainless steel?

A: UE6120 is for General Steel. For stainless steel, we recommend MP735 or US735 for better chemical resistance.

Expert Performance Tip: CVD Toughness vs. Speed

For General Purpose & Interrupted Turning, use UE6120 to prevent chipping. If your machine is stable and the cut is continuous, use UE6110 to push the cutting speed further.

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.
