MITSUBISHI WNMG060404-MS US735

The Stainless Steel Machining Specialist | 100% Made in Japan

Product Overview

The Mitsubishi WNMG060404-MS US735 is a premium, double-sided 80° trigon negative insert specifically engineered for stainless steel turning. Manufactured in Japan, the US735 CVD coating is designed to overcome the high heat and work-hardening challenges of austenitic stainless steels. With a sharp 0.4mm corner radius and the MS chipbreaker, this indexable carbide insert provides superior chip control and a mirror-like surface finish in light to medium CNC machining applications.

Specialized Grade: US735 (Stainless Specialist)

The US735 grade is Mitsubishi's dedicated solution for the M-Class material group. Turning stainless steel often results in "built-up edge" (BUE) and sudden chipping. US735 features a high-toughness carbide substrate paired with a specialized CVD coating that offers excellent thermal shock resistance and reduces material welding, extending tool life in tough machining conditions.

MS Chipbreaker Geometry

The MS chipbreaker is specifically optimized for finishing and light-to-medium cutting. For stainless steel, it features a sharp cutting edge that minimizes work hardening of the material surface. The unique land design ensures stable chip control even at small depths of cut, making it ideal for high-precision components.

Recommended Cutting Parameters

Optimized for Stainless Steel (M-Class):

  • Cutting Speed (Vc): 80 - 180 m/min (260 - 590 SFM)
  • Feed Rate (f): 0.08 - 0.25 mm/rev (0.003 - 0.010 ipr)
  • Depth of Cut (ap): 0.3 - 2.5 mm

*Note: Use high-pressure coolant to improve chip evacuation and cooling when machining 300-series stainless.*

Global Customer Feedback

⭐⭐⭐⭐⭐ "Stainless Master" - David K., USA
"US735 is the only grade that doesn't chip on 316 stainless for us. The MS breaker keeps chips nice and short."

⭐⭐⭐⭐⭐ "Top Finish" - Hans B., Germany
"Authentic Mitsubishi quality. The 0.4mm radius gives a fantastic surface finish on precision valve parts."

⭐⭐⭐⭐ "Very Sharp" - Kenji O., Japan
"Very sharp edge. Greatly reduces the friction heat when turning gummy stainless alloys."

⭐⭐⭐⭐⭐ "Economic 6 Edges" - Liam N., Australia
"WNMG trigon inserts are so much better value than diamond shapes. 6 edges of US735 for this price is unbeatable."

⭐⭐⭐⭐⭐ "Predictable Wear" - Piotr L., Poland
"Predictable tool life. No sudden breakages, which is essential for our CNC lathe automation."

Technical Q&A

Q: Can I use US735 for regular Steel?

A: While it can cut steel, US735 is optimized for Stainless Steel. For carbon steel, MC6025 will offer better performance and wear resistance.

Q: What is the benefit of the MS chipbreaker?

A: The MS (Medium-Sharp) geometry is designed to prevent "bird-nesting" of chips in stainless steel, providing smooth chip evacuation.

Q: Is this insert suitable for roughing?

A: This 0.4mm radius insert is best for finishing and light cutting. For heavy roughing, we recommend a 0.8mm or 1.2mm radius.

Expert Machining Tip: US735 vs VP15TF

For General Stainless Steel and high productivity, use US735. For Small-Part Precision and universal material flexibility, VP15TF is a great alternative.

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.
