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.
