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

How do I choose the correct specification?

When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.

How can I check compatibility with my existing setup?

For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.

What quantity and price unit am I ordering?

Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.

How should I choose cutting parameters?

Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.

Are bulk discounts available?

Our automatic quantity discount is 6% off for 2–9 items and 12% off for 10 or more items, based on the total product quantity in the cart. Other offers may not combine with this discount; check the applicable offer conditions.
