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

Are your carbide inserts interchangeable with major brands like Sandvik, Iscar, or Kennametal?

Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.

How do I choose the correct insert grade and chipbreaker for machining Stainless Steel (M) vs. Carbon Steel (P)?

We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:

  • For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
  • For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
What are the recommended cutting speed (Vc) and feed rate (f) parameters to maximize tool life?

The optimal cutting parameters vary depending on the workpiece hardness and operation type:

  • For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
  • For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
Do you offer bulk discounts or wholesale pricing for machine shops and distributors?

Yes, we support machine shops, distributors, and global buyers with tiered wholesale pricing and competitive volume discounts. We also provide OEM custom manufacturing solutions for tool holders and carbide inserts based on your technical drawings. Contact our team to request a quick B2B quotation.

What is your international shipping policy and typical lead time for orders?

We provide secure worldwide express shipping (via DHL, FedEx, and UPS) with specialized, vibration-proof industrial packaging to ensure tools arrive in perfect condition. In-stock items are dispatched within 24-48 hours, while custom or bulk orders typically have a stable lead time of 15-25 days.

How do you guarantee the quality and tolerance precision of your CNC tools?
