MITSUBISHI WNMG080408-MA MC5005

The High-Speed Cast Iron Machining Specialist | 100% Made in Japan

Product Overview

The Mitsubishi WNMG080408-MA MC5005 is a premium, double-sided 80° trigon negative insert specifically engineered for high-speed turning of cast iron. Manufactured in Japan, the MC5005 CVD coating features a thick Al2O3 layer that provides industry-leading wear resistance against the abrasive nature of gray and nodular cast iron. With a versatile 0.8mm radius and the MA chipbreaker, this indexable carbide insert ensures maximum productivity and exceptional tool life in continuous to light interrupted CNC machining environments.

Advanced Grade: MC5005 (CVD Coating)

The MC5005 grade is the pinnacle of Mitsubishi's cast iron turning technology. Utilizing a specialized CVD multi-layer coating with enhanced adhesion, it resists the flank wear and crater wear typical when machining Gray Cast Iron (FC) and Ductile Cast Iron (FCD). It allows for ultra-high cutting speeds, significantly reducing cycle times in mass production.

MA Chipbreaker Geometry

The MA chipbreaker is an all-purpose medium-range geometry. For cast iron, it provides excellent chip control and heat dissipation. The land design reinforces the cutting edge against the high-pressure loads found in K-class material turning, preventing edge micro-chipping and ensuring a consistent surface finish.

Recommended Cutting Parameters

Optimized for Cast Iron (K-Class):

  • Cutting Speed (Vc): 200 - 500 m/min (655 - 1640 SFM)
  • Feed Rate (f): 0.15 - 0.45 mm/rev (0.006 - 0.018 ipr)
  • Depth of Cut (ap): 0.5 - 4.0 mm

*Note: MC5005 is designed for speed. If machining at lower speeds, consider MC5015 for increased toughness.*

Global Customer Feedback

⭐⭐⭐⭐⭐ "High Speed Master" - Robert B., USA
"We pushed the speed to 450m/min on gray iron. The MC5005 held up amazingly. Predictable wear."

⭐⭐⭐⭐⭐ "Genuine Mitsubishi" - Hans G., Germany
"Authentic Japanese quality. Tool life is twice as long as the cheaper grades we were using for ductile iron."

⭐⭐⭐⭐ "Great Stability" - Kenji T., Japan
"Very stable on our high-speed CNC lathes. MA chipbreaker handles the short chips well."

⭐⭐⭐⭐⭐ "Economic 6 Edges" - Liam F., Australia
"The WNMG trigon is perfect for mass production. 6 edges per insert plus MC5005 speed = huge savings."

⭐⭐⭐⭐⭐ "Fast Delivery" - Andrej P., Poland
"Arrived in original packaging. Best price for high-tier cast iron inserts."

Technical Q&A

Q: Can I use MC5005 for Steel?

A: MC5005 is optimized for Cast Iron. For Steel, we recommend MC6025 or UE6110 for better performance.

Q: Why choose the Trigon (W-shape) over Diamond (C-shape)?

A: The WNMG shape offers 6 usable edges instead of 4, significantly lowering your cost per part without sacrificing tool strength.

Q: Does it require coolant?

A: Cast iron can be machined dry, but using high-pressure coolant with MC5005 can further improve surface finish and evacuate dust.

Expert Performance Tip: MC5005 vs MC5015

For Continuous High-Speed Machining of gray iron, use MC5005. If you encounter Interrupted Cuts or need more edge toughness for ductile iron, choose MC5015.

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.

When will my order ship and arrive?
