MITSUBISHI WNMG06T308-MS US735

Professional Stainless Steel Machining Specialist | 100% Made in Japan

Product Overview

The Mitsubishi WNMG06T308-MS US735 is an industry-leading, 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 robust 0.8mm 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-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 0.8mm radius provides increased edge strength compared to the 0.4mm version, allowing for higher feed rates on your CNC lathe while maintaining dimensional accuracy.

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 high-pressure coolant to maximize the performance of the US735 grade.*

Global Customer Feedback

⭐⭐⭐⭐⭐ "Workhorse for Stainless" - Mark T., USA
"The US735 grade is my go-to for 304 and 316. It handles the work-hardening better than anything else I've tried."

⭐⭐⭐⭐⭐ "Stable and Reliable" - Hans R., Germany
"Authentic Mitsubishi parts. The 0.8mm radius is very strong for medium roughing in stainless steel."

⭐⭐⭐⭐ "Great Chip Control" - Kenji S., Japan
"MS chipbreaker works wonders on gummy materials. No more stringy chips wrapping around the spindle."

⭐⭐⭐⭐⭐ "Excellent Value" - Liam F., Australia
"6 edges per insert makes these very economical. Fast shipping and the real deal."

⭐⭐⭐⭐⭐ "Precision Quality" - Piotr W., Poland
"Highly recommended for CNC job shops. The predictable tool life makes planning so much easier."

Technical Q&A

Q: Why choose US735 over VP15TF?

A: US735 is a CVD grade specifically optimized for the heat and abrasion of stainless steel, whereas VP15TF is a more universal PVD grade.

Q: What is the benefit of the 0.8mm radius?

A: The 0.8mm (08) radius offers higher edge strength and allows for faster feed rates compared to the 0.4mm (04) radius.

Q: How many cutting edges are included?

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

Expert Machining Tip: US735 vs MC7025

For General Stainless Steel production, US735 is a proven classic. If you require higher cutting speeds in stable conditions, consider the newer MC7025 grade.

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.
