MITSUBISHI WNMG080408-MA UE6120

The Toughness Specialist for Interrupted Steel Cutting | 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, making it the premier choice for machining carbon and alloy steels where cutting is not continuous. Combined with the versatile MA chipbreaker and a robust 0.8mm radius, this indexable carbide insert ensures reliability in the most demanding CNC machining environments.

Advanced Grade: UE6120 (Toughness Benchmark)

The UE6120 grade is Mitsubishi's specialized CVD coated carbide designed for interrupted steel turning. It features a high-toughness substrate paired with a multi-layer coating that resists impact shock and thermal cracking. This grade is the industry standard for machining alloy steels and carbon steels in unstable conditions or when processing parts with keyways and holes, ensuring a long and predictable tool life.

MA Chipbreaker Performance

The MA (Medium-range) chipbreaker is an all-rounder. It balances sharp cutting action with a reinforced land for edge stability. It provides excellent chip control across a wide variety of feed rates, preventing chip wrapping and protecting your CNC lathe tool holder from damage.

Recommended Cutting Parameters

Optimized for Steel / Alloy Steel (P-Class):

  • Cutting Speed (Vc): 120 - 240 m/min (390 - 790 SFM)
  • Feed Rate (f): 0.15 - 0.45 mm/rev (0.006 - 0.018 ipr)
  • Depth of Cut (ap): 0.8 - 4.5 mm

*Note: For heavy interrupted cuts, reduce cutting speed by 15-20% for maximum stability.*

Customer Reviews & Feedback

⭐⭐⭐⭐⭐ "Standard for Steel" - Mark T., USA
"UE6120 is the only grade that doesn't chip on my keyed shafts. Consistent tool life and clean cuts."

⭐⭐⭐⭐⭐ "Genuine Japanese Quality" - Hans K., Germany
"Exactly as described. Authentic Mitsubishi tools. The tool life is double that of the budget brands we tried."

⭐⭐⭐⭐ "Great Stability" - Kenji S., Japan
"Stable cutting even at high speeds. Very satisfied with the chip control on our CNC lathe."

⭐⭐⭐⭐⭐ "Fast Shipping" - Liam J., Australia
"Arrived quickly in original packaging. 6 usable edges per insert makes it highly cost-effective."

⭐⭐⭐⭐⭐ "Highly Recommended" - Andrej B., Poland
"The best for medium roughing in alloy steel. Zero issues with cratering or edge wear."

Technical Q&A

Q: Can I use this for stainless steel?

A: UE6120 is optimized for general steel. For stainless steel, we recommend grades like US735 or MP735 for better performance.

Q: What is the benefit of the Trigon (W-shape) insert?

A: The 80° trigon provides 6 usable edges, making it more economical than 4-edged CNMG inserts while maintaining high strength.

Q: Is this suitable for high-speed continuous cutting?

A: While UE6120 can handle it, the UE6110 grade is better optimized for purely continuous high-speed turning.

Expert Machining Tip: UE6110 vs. UE6120

For Stable Continuous Turning, choose UE6110 for maximum wear resistance. For General/Interrupted Turning, stick with UE6120 for superior toughness and shock protection.

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.
