MITSUBISHI WNMG06T304-MA US735

Precision Stainless Steel Specialist | Toughened CVD Coated Carbide

Product Overview

The Mitsubishi WNMG06T304-MA US735 is a high-performance, double-sided 80° trigon negative insert specifically engineered for turning stainless steel. Featuring the industry-proven US735 CVD coating, this insert provides exceptional resistance to thermal cracking and notch wear. The MA chipbreaker ensures smooth chip evacuation during medium-duty CNC machining, making it a reliable choice for both continuous and interrupted cuts in austenitic and duplex stainless steels.

Material Excellence: US735 CVD Coating

The US735 grade is a specialized CVD coated carbide that balances toughness and wear resistance. It is optimized for interrupted cutting of stainless steel, where vibration and thermal shock are prevalent. The coating effectively resists built-up edge (BUE), which is critical for maintaining surface integrity on precision parts.

MA Chipbreaker Performance

The MA (Medium-range) chipbreaker features a balanced cutting edge that provides excellent chip control across a variety of feed rates. This geometry prevents long, stringy chips from wrapping around the indexable tool, reducing downtime and protecting the workpiece finish during CNC turning operations.

Recommended Cutting Parameters

Optimized for Stainless Steel (M-Class):

  • Cutting Speed (Vc): 80 - 180 m/min (260 - 590 SFM)
  • Feed Rate (f): 0.12 - 0.35 mm/rev (0.005 - 0.014 ipr)
  • Depth of Cut (ap): 0.5 - 3.0 mm

*Pro Tip: Ensure stable clamping and consistent coolant flow to maximize tool life in stainless applications.*

Global Customer Feedback

⭐⭐⭐⭐⭐ "Reliable for 304/316" - David K., Canada
"The US735 grade handles 316 stainless with ease. No chipping even with light interruptions. These are original and work perfectly."

⭐⭐⭐⭐⭐ "Great Chip Control" - Hans B., Germany
"The MA chipbreaker is very versatile. We use it for medium-duty turning on our CNC lathes and the chip evacuation is excellent."

⭐⭐⭐⭐ "Consistent Tool Life" - Yuki M., Japan
"Authentic Mitsubishi inserts. Tool life is very predictable, which is essential for our production runs. Good value for money."

⭐⭐⭐⭐⭐ "Fast Shipping" - Liam J., Australia
"Received these quickly. They perform much better than the generic alternatives on stainless steel. Definitely buying again."

⭐⭐⭐⭐⭐ "Excellent Finish" - Marco S., Italy
"The 0.4mm radius provides a very clean surface finish on stainless shafts. Very satisfied with the toughness of the US735 coating."

Technical Q&A

Q: Can I use WNMG06T304 on carbon steel?

A: Yes, it can be used, but US735 is optimized for the toughness of stainless steel. For general steel, a grade like MC6025 would be more efficient.

Q: What is the benefit of the trigon shape?

A: The 80° trigon shape provides the strength of a square insert with the versatility of a rounder shape, offering 6 cutting edges total.

Q: Is this insert suitable for high speeds?

A: US735 is a toughened grade. While it handles moderate speeds well, it is primarily designed for stability and toughness in difficult stainless steel cuts.

Material Choice Tip: US735 vs. MS6015

For Medium Stainless Turning, choose US735 for its superior toughness. If you are doing light finishing on small parts with high precision requirements, consider MS6015 for better sharpness and heat resistance on the cutting edge.

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?

All our cutting tools and tool holders are manufactured strictly in accordance with ISO 9001 and international industrial standards. Every batch undergoes 100% rigorous quality control testing using high-precision optical measuring equipment to ensure reliable tool life and stable performance in continuous mass production.
