MITSUBISHI WNMG080412-GH UC5115

Heavy-Duty Cast Iron Roughing Expert | 1.2mm Corner Radius | Made in Japan

Product Overview

The Mitsubishi WNMG080412-GH UC5115 is a powerhouse double-sided 80° trigon negative insert, specifically engineered for the most demanding cast iron turning applications. Featuring a robust 1.2mm corner radius for maximum edge strength and the specialized UC5115 CVD coating, this insert excels in high-speed roughing of gray and ductile iron. The GH chipbreaker provides a reinforced cutting edge, making this indexable carbide insert a premier choice for CNC machining environments where high metal removal rates and exceptional tool life are required.

Advanced Grade: UC5115 (Wear Resistant CVD)

The UC5115 grade represents the pinnacle of Mitsubishi’s CVD technology for cast iron. It features a high-density coating structure that resists the abrasive nature of gray and ductile iron particles. This grade is optimized for continuous cutting at high speeds, significantly reducing crater wear and plastic deformation on your CNC lathe.

GH Chipbreaker Geometry

The GH (General Heavy) chipbreaker is purpose-built for heavy roughing. With a robust cutting edge and land width, it handles high depth-of-cut (ap) and aggressive feed rates. The large 1.2mm radius (12) further enhances edge strength, allowing the insert to survive heavy interrupted cuts and rough casting surfaces with ease.

Recommended Cutting Parameters

Optimized for Cast Iron (K-Class):

  • Cutting Speed (Vc): 150 - 350 m/min (490 - 1150 SFM)
  • Feed Rate (f): 0.25 - 0.60 mm/rev (0.010 - 0.024 ipr)
  • Depth of Cut (ap): 1.2 - 4.5 mm

*Pro Tip: Thanks to the 1.2mm radius, you can push higher feed rates while maintaining process security.*

Verified Global Customer Reviews

⭐⭐⭐⭐⭐ "Heavy Duty Performance" - Mark S., USA
"The 1.2mm radius on UC5115 is incredible. We rough out ductile iron housings all day and the edge holds up perfectly."

⭐⭐⭐⭐⭐ "Consistent Tool Life" - Dieter B., Germany
"Very reliable CVD grade. We run these at high speeds and the wear is very predictable. Original Japanese quality."

⭐⭐⭐⭐ "Great Chip Control" - Kenji T., Japan
"Even on rough castings, the GH breaker manages chips well. No edge chipping observed so far."

⭐⭐⭐⭐⭐ "Cost-Effective 6 Edges" - Liam J., Australia
"WNMG is the best value. 6 edges with UC5115 toughness makes this a very economical choice for our shop."

⭐⭐⭐⭐⭐ "Original Packaging" - Pavel D., Poland
"Authentic Mitsubishi inserts. Fast shipping and they perform exactly as the technical data suggests."

Technical Q&A

Q: Can I use UC5115 for Steel?

A: UC5115 is specialized for Cast Iron (K-Class). For steel, please use UE6110 or MC6025 for better results.

Q: Why choose the 1.2mm radius over the 0.8mm?

A: The 1.2mm radius provides significantly higher edge strength, making it superior for heavy roughing and interrupted cuts.

Q: Is this insert compatible with standard holders?

A: Yes, it fits any standard MWLNR / DWLNR turning tool holder designed for 08 size WNMG inserts.

Expert Machining Tip: UC5115 vs MC5015

For General High-Speed Cast Iron roughing, UC5115 is legendary. For Highly Abrasive Ductile Iron finishing, consider the MC5015 grade for improved wear resistance.

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.
