MITSUBISHI WNMG080412-GK MC5015

Heavy-Duty Cast Iron Turning Specialist | 1.2mm Radius | Made in Japan

Product Overview

The Mitsubishi WNMG080412-GK MC5015 is a robust, double-sided 80° trigon negative insert engineered for high-performance cast iron turning. Featuring a large 1.2mm corner radius for maximum edge strength, it is powered by the MC5015 CVD coating to combat the abrasive nature of gray and ductile iron. Designed for CNC machining professionals, the GK chipbreaker ensures stable cutting even during heavy-duty applications, providing exceptional tool life and process reliability in high-speed environments.

Advanced Grade: MC5015 (The Cast Iron Master)

The MC5015 grade is Mitsubishi's premier solution for high-speed cast iron machining. It features a Nano-Texture CVD coating that offers incredible abrasion resistance and thermal stability. This grade is specifically optimized for high-speed continuous cutting of gray and ductile iron, preventing plastic deformation and ensuring consistent tool life across production batches.

GK Chipbreaker Geometry

The GK chipbreaker is designed for high stability and edge reliability. In precision machining of cast iron, maintaining edge integrity is vital due to the material's abrasive nature. The GK geometry, paired with the large 1.2mm radius, is perfect for heavy-to-medium stable cutting, providing excellent process security even on rough casting surfaces.

Recommended Cutting Parameters

Optimized for Cast Iron (K-Class):

  • Cutting Speed (Vc): 150 - 450 m/min (490 - 1470 SFM)
  • Feed Rate (f): 0.20 - 0.50 mm/rev (0.008 - 0.020 ipr)
  • Depth of Cut (ap): 0.8 - 4.5 mm

*Pro Tip: Use the large 1.2mm radius to your advantage by increasing the feed rate for maximum productivity.*

Global Verified Customer Feedback

⭐⭐⭐⭐⭐ "Extreme Durability" - Mark T., USA
"The 1.2mm radius on these MC5015 inserts is a beast for our ductile iron housings. Tool life is fantastic."

⭐⭐⭐⭐⭐ "High Speed Performance" - Stefan H., Germany
"We run these at 400m/min and they just don't quit. Very stable and the surface finish on the iron is excellent."

⭐⭐⭐⭐ "Very Reliable" - Yuki M., Japan
"Consistent results every time. The GK breaker is perfect for our heavy casting work. Authentic quality."

⭐⭐⭐⭐⭐ "Great Cost-Per-Edge" - Liam F., Australia
"WNMG provides 6 usable edges. Combined with MC5015 durability, it's the most economical choice for our CNC shop."

⭐⭐⭐⭐⭐ "Fast Delivery" - Ivan R., Poland
"Ordered a box of 10, arrived in original packaging. These performed exactly as specified in the Mitsubishi catalog."

Technical Q&A

Q: Can I use MC5015 for Steel?

A: MC5015 is specialized for Cast Iron (K-Class). For steel, we recommend the MC6025 or UE6110 grades for optimal performance.

Q: What are the benefits of the 1.2mm radius?

A: A 1.2mm radius (12) provides much higher edge strength and allows for higher feed rates, making it ideal for heavy-duty machining.

Q: Is this insert compatible with standard WNMG holders?

A: Yes, it fits all standard MWLNR / DWLNR holders. The trigon shape offers 6 edges, giving you superior value over CNMG.

Expert Machining Tip: MC5015 vs MC5005

For General Purpose Cast Iron machining, MC5015 is your best choice. If you are focused solely on Continuous High-Speed Cutting of Gray Iron, consider MC5005 for maximum 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.
