MITSUBISHI WNMG06T304-MS US735

The Stainless Steel Finishing Expert | 100% Made in Japan

Product Overview

The Mitsubishi WNMG06T304-MS US735 is a specialized, double-sided 80° trigon negative insert precision-engineered for stainless steel turning. Optimized for high-reliability CNC machining, the US735 CVD coating provides incredible resistance to thermal cracking and adhesive wear, common issues when cutting gummy austenitic stainless steels. With a sharp 0.4mm corner radius and the MS chipbreaker, this indexable carbide insert is your premier choice for achieving superior surface finishes and stable tool life in medium-to-light duty precision turning.

Advanced Grade: US735 (The Stainless Master)

The US735 grade is Mitsubishi's benchmark for tough-to-machine stainless steel. It features a high-toughness carbide substrate combined with a specialized CVD coating that effectively manages heat and prevents chemical wear. This grade is specifically designed to handle the abrasive nature of stainless while maintaining an incredibly stable cutting edge, preventing sudden chipping and extending tool life.

MS Chipbreaker Geometry

The MS (Medium-Sharp) chipbreaker is designed for light-to-medium cutting. For stainless steel, the MS geometry is critical for preventing "built-up edge" (BUE) and managing chip control in gummier materials. The sharp edge reduces the radial force on the workpiece, ensuring high-precision dimensions and an exceptional surface finish on your CNC lathe 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 - 2.0 mm

*Pro Tip: Ensure stable clamping and high-pressure coolant to maximize the performance of the US735 grade.*

Global Customer Feedback

⭐⭐⭐⭐⭐ "Stainless Specialist" - David K., USA
"US735 is the only grade that consistently handles 316 stainless in our shop. The MS breaker prevents bird-nesting of chips perfectly."

⭐⭐⭐⭐⭐ "Mirror Finish" - Hans B., Germany
"The 0.4mm radius gives an incredible finish on small precision parts. Authentic quality from Japan."

⭐⭐⭐⭐ "Very Stable" - Kenji O., Japan
"Consistent tool life across large batches. Reduced our downtime significantly compared to cheaper alternatives."

⭐⭐⭐⭐⭐ "Excellent Economy" - Liam N., Australia
"6 usable edges of US735 for this price is unbeatable. WNMG trigon shape is the smartest choice for CNC turning."

⭐⭐⭐⭐⭐ "Highly Recommended" - Piotr L., Poland
"Fast shipping and original packaging. These inserts handled heat-resistant alloys better than expected."

Technical Q&A

Q: Can I use US735 for carbon steel?

A: While it can cut steel, US735 is optimized for Stainless Steel turning. For carbon steel, MC6025 or UE6110 will offer better wear resistance and economy.

Q: What makes the MS breaker different from MA?

A: The MS geometry is sharper and designed for finishing and light cutting, whereas the MA is a more robust medium-range breaker.

Q: How many cutting edges are available?

A: WNMG is a double-sided negative insert, providing 6 usable edges per insert, making it very cost-effective.

Expert Machining Tip: US735 vs VP15TF

For dedicated Stainless Steel Production, use US735. If you are a job shop needing a Universal Grade for steel, stainless, and cast iron, VP15TF is the better flexible 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.
